INTRODUCTION
Menopause is defined retrospectively as the time of final menstrual
period followed by 12 months of amenorrhea.1
Average age of menopause for Indian women is 47years.
Postmenopausal bleeding is bleeding from the reproductive system that
occurs one year or more after menstrual periods have stopped. Bleeding
from the genital tract occurring after the menopause is much more sinister
than premenopausal bleeding. In defining postmenopausal bleeding, the
question arises as to when the menopause can be regarded as established.
Even without amenorrhea or irregularity, menstruation continuing after
the age of 55 years should beinvestigated.2
The main objective in the diagnostic workup in postmenopausal women
presenting with uterine bleeding is to detect or rule out endometrial
cancer or atypical hyperplasia, further referred to as (pre) malignancy of
the endometrium. As most cases are found to be benign, the goal of
clinical management is to achieve an accurate diagnosis without
Organic pathology, causing uterine bleeding in postmenopausal women
include endometrial polyps, endometrial hyperplasia and endometrial
carcinoma. More often an organic cause is not identifiable, and the
histopathology may show atrophic endometrium, proliferative
endometrium and rarely secretoryendometrium.4
At least 20 - 25%of postmenopausal women with bleeding is said to have
a neoplastic lesion; approximately 10-15% of which is having
endometrialcarcinoma1.
The carcinoma of endometrium is one of the most common female
pelvic malignancy and ranks fifth most common cancer in females after
cervix, breast, oral cavity and ovarian malignancies5. The relatively low
mortality for this cancer is probably due to the fact that most of these
patients turn up for consultation at an early stage with symptoms of
postmenopausal bleeding. The recent rise in the incidence of endometrial
carcinoma may be related to the decreased incidence of cervical
carcinoma , prolonged life expectancy and earlier diagnosis.
Both endometrial thickness and the risk of endometrial
carcinoma are found to be associated with Various other individual risk
diabetes mellitus and parity. These risk indicators might be used for
AIM & OBJECTIVES OF THE STUDY
1. To establish the various endometrial causes of
postmenopausal bleeding, through histopathological evaluation.
2. To correlate the clinical and histopathological
findings.
3.This study also evaluates the relation between age
REVIEW OF LITERATURE
ANATOMY OF ENDOMETRIUM
Endometrium, the lining mucosa of the uterus is a labile tissue
hormonally, responsive to sex steroids secreted in the ovary. In the first
half of the menstrual cycle, endometrium undergo proliferation under the
influence of estrogens, and in the later half it responds to progesterone so
that it leads to stromal alterations necessary for implantation of a
fertilized ovum.
The adult uterus measures 50-80 grams. It measures 7-9 cm in length,4.5
– 6 cm in width and antero posterior thickness of 4 cm. The endometrium
varies from 1-8 mm thickness and the myometrium averages 1.5 – 2.5
cmthickness.6
During menopause ,the endometrium becomes thin and inactive, because
of the failure of the ovary to respond to gonadotrophic hormones. Inactive
endometrium becomes thin and may measure 1mm in thickness.
BLOOD SUPPLY :
Main blood supply to the endometrium, is by branches of uterine artery
Two types of arteries supply the endometrium , one of these is limited to
the basal third and consists of small straight and short arteries. The
superficial two thirds of the endometrium is being supplied by coiled
arteries. The veins follow the arteries, and drain into the pelvic plexus of
veins.
LYMPHATICS :
The lymphatic’s from basal layer of endometrium run through
myometrium in close relation to the blood vessels to reach the
subserosalplexus.Through the parametrium and ovarian ligament, they
communicate with the ovarian lymphatics to terminate in the pre aortic
lymph nodes. The lymphatic’s from the lower uterine segment drains to
the obturator, iliac, hypogastric and sacral nodes.6
HISTOLOGY OF ENDOMETRIUM :
The endometrium of the uterus is composed of 2 layers :
1) The basalis is the layer from which the endometrium, regenerates after
menstrual shedding.
2) The overlying functionalis layer , may be differentiated into the
superficial compactum and the underlying spongiosa, which extends to
During menstrual cycle, the endometrium varies from 1 mm
(postmenstrual) to 8mm , at the end of the 3rd week. Every layer consists
of 2major components, the epithelial component, either as glands or as
superficial epithelium and the mesenchymal component of stromal cells,
with pleuri potential properties.
1) The glandular epithelium :
It is a single layer of , columnar epithelial cells. Their height varies
depending on the functional (hormonal) state from 6mm postmenstrual,
to20mm at the end of the proliferative phase. During ,the proliferative
phase, the nuclei of the glandular cells are elongated and have a dense
chromatin. During the secretory phase, the nuclei become round,
vesicular and gradually lose their DNA.The apical surface of the
epithelial cells is the proliferative phase, possess elongated delicate
microvilli which contain alkaline phosphatases.During the secretory
phase, as these microvilli draw back and disappear, the activity of
alkaline phosphates diminishes. It is sometimes, possible to find ciliated
cells among the glandular epithelial cells. Each cell always has just 11
cilia. The number of ciliated cells , fluctuates considerably , from patient
to patient depending on the functional state of the endometrium. The
2) The superficial epithelium:
It contains, greater number of ciliated cells than does, the glandular
epithelium during the proliferative phase.
3) The stromal cells :
The endometrial stroma consists of pleuripotential
mesenchymal cells, which at the beginning of the menstrual cycle, are
uniformly spindle shaped, poorly differentiated and joined to one another
by cytoplasmic processes. The cells lie firmly anchored within a delicate
network of reticulum fibres. Characteristically, it is spindle shaped with
scant cytoplasm surrounding a bursiform nucleus. In addition, to
fibroblasts, leucocytes, mast cells and plasma cells are frequently found
in the stroma.
4) The reticulum fibers :
The reticulum fibers, in contrast to collagen fibers may be reformed
within a few days ,giving rise to a dense reticular network. While the
stroma of the basalis and isthmus mucosa remains uniformly dense, the
content of fibres in the stratum functionalis, fluctuates considerably
made out during the first 8 days of the proliferative phase. As ovulation
approaches, these fibers became smaller and thicker. During the secretory
phase, they are temporarily pulled apart, by the transistory edema that
develops. By 4th week of the cycle, they surround each predecidual cell
and form a dense network around the glands and spiral arterioles. With
the decrease in progesterone level the reticulum fibres disintegrate.
5)The vessels :
The vessels of the stratum functionalis of the endometrium , are very
much sensitive to hormones where as the vessels of the basalis are not
influenced by hormonal changes of the cycle. There is an irregular
network of venous channels with the veins frequently intersecting
forming venous lakes.6
ENDOCRINE CHANGES AT MENOPAUSE
The basic feature of menopause is that the
primordial follicle, and its derivatives, the granulosa cells and the
surrounding theca cells degenerate, or fail to react to endogenous
gonadotrophins. The stromal cells produce the androgens,
androstenedione, testosterone and deydroepiandrosterone in thenormal
premenopausal ovary, and this process continues in the postmenopausal
Thus in the postmenopausal women, about 40 g/day of estrone, is
excreted and virtually none of it is secreted by the ovary, almost all of it
is, derived from androstenedione. The androstenedione is secreted
largely from adrenal gland, and conversion occurs peripherally; that is
outside ovary, which is the adipose tissue and this suggests why
carcinoma of corpus uteri is common in obese women.7
Plasma estradiol levels decrease, gradually over the first year or so of
menopausal amenorrhea. With eventual loss of all follicular activity, the
ovary ceases, to be an estrogen secreting organ. The hormonal status of
postmenopausal women has been studied. The most important feature of
menopause is that estradiol ceases to be the major circulating estrogen
and is present at levels of 20-25 pg/ml or less.
The adrenal glands are the major site of sex hormone, production, in
postmenopausal women. Estrogens in postmenopausal women originate
almost completely from the so called peripheral conversion of androgens
to estrogens.
ENDOMETRIUM AFTER MENOPAUSE :
Once the ovaries cease their cyclic production of estrogen and
progesterone, the endometrium is no longer subject to its normal
stimulation and it undergoes atrophy. The endometrium after the
thickness and becoming quite atrophic in the elderly. The glands are
typically small and sparse, and are often not evenly distributed
throughout the tissue. They exhibit an epithelium composed of cuboidal
or flattened cells. The stroma becomes fibrous and the stromal cells, lose
virtually all their cytoplasm, the stroma of the postmenopausal
endometrium may appear remarkably cellular. Commonly the
endometrium is so thin, and meager in amount that biopsy specimens
yield only strips of atrophic surface endometrial epithelium. Exposure to
low levels of estrogen, either exogenous or endogenous, can result in a
mildly expanded endometrium in which rare mitoses can be seen. This is
quaintly referred to as 'weakly proliferative endometrium’.
The presence of a proliferative endometrium in a woman past the age of
60 years is abnormal and in the absence of a history of exogenous
estrogen usage, is regarded by many as hyperplasia.9
ETIOLOGY OF POSTMENOPAUSAL BLEEDING10
1) Vulva :Vulvitis, trauma, benign and malignant lesions.
2) Vagina : Foreign body such as ring pessary for prolapse, senile
vaginitis, vaginal tumors, vaginal cancer, post radiation Vaginitis.
3) Cervix :Benign cervical erosion, polyp, cervicitis, decubitus ulcer
4) Uterus : Senile endometritis, tuberculous endometritis, endometrial
polyp, endometrial hyperplasia and endometrial carcinoma.
5) Fallopian tube malignancy.
6) Ovary : Benign ovarian tumors such as Brenner tumour, hormone
secreting granulosa cell tumor and theca cell tumor, malignant ovarian
tumor.
7) Blood dyscrasias
8) Bowel & Urinary tract : : Urethral caruncle, papilloma , carcinoma of
bladder, Bleeding from hemorrhoids and fissures & Rectal cancer may be
misinterpreted by the patient as vaginal bleeding.

1) ENDOMETRIAL ATROPHY :
Bleeding associated with endometrial atrophy, related to
insufficient estrogen stimulation may develop in women taking "oral
contraceptives", in postmenopausal women with naturally occurring
atrophy, in young women with premature ovarian failure or following
radiation for cervical cancer.
Atrophy and weakly proliferative patterns, are normal in menopausal and
peri-menopausal women as well as in pre-pubertal girls. Atrophic
endometrial, are most commonly recovered in the endometrial biopsy
sample, from patients with postmenopausal bleeding. Atrophy may
account for upto82% of postmenopausal vaginal spotting or bleeding. The microscopic appearance of atrophic endometrium is different in
hysterectomy and biopsy specimens.
In hysterectomy specimens, the endometrium is thin, and composed of variably sized glands that are often cystic and surrounded by a diminished
amount of compact stroma, compared with endometrial from
Biopsy or curettage specimens of atrophic endometrium, typically
consists of scant mucus with rare fragments and strips of cuboidal or
columnar cells. Intact glands may be absent and only small clusters of
stromal cells with dark ovoid nuclei resembling those seen in anovulatory
bleeding are observed.11
The epithelium tends to be mitotically inactive, and bland in terms of cytologic appearance. The glands are embedded in a similarly
“inactive”spindled stroma that exhibits varying degrees of collagenation
and practically no mitotic activity. The ratio of glands to stroma is near unity, although pattern uniformity is variable. The glandular architecture may be cystic, or budded, and the buds may even be closely packed; as
in hyperplastic endometrium typically; however the glands are tubular.
Occasionally, the epithelium may be metaplastic.Weakly proliferative
endometrium, differ from those that are atrophic by virtue of cells with
pseudostratified, elongated, densely basophilic nuclei, rather than the
cuboidal or flattened nuclei characteristic of the cells that ,populate an atrophic endometrium.
Cystic atrophy is the term applied to endometrium composed predominantly of cystically dilated glands lined by cuboidal to flattened
2) ENDOMETRIAL POLYPS :
Endometrial polyps are benign, localized overgrowths of endometrial glands and stroma, that are covered by epithelium, and project above the adjacent surface epithelium. Polyps arise as monoclonal overgrowths,
of genetically altered endometrial stromal cells, with secondary induction
of polyclonal benign glands, through as yet undefined' stromal – epithelial interactive mechanisms'. Chromosomal analysis of polyp stroma shows in the majority of cases clonal translocations, involving,
6p21-22, 12q13-15 or 7q22 ,regions.
Endometrial polyps variably respond to circulating estrogens, and
progesterone. The glands in the polyp may, sometimes be
indistinguishable , from those in the rest of the endometrium , but this is
unusual. If the stroma is
made up predominantly of smooth muscle but the glands are not atypical,
the term adenomyoma is employed.
MORPHOLOGICAL FEATURES :
Endometrial polyps range in size from a slightly rounded, to a large broad
based or pedunculated, oval structure filling the uterine cavity. Many
polyps are sessile, and have a broad base of attachment. 20%polyps, are
multiple. The surface may be smooth and shiny, often, hemorrhagic
Microscopy :The diagnosis of a polyp in a curetting depends upon the finding of at least two , of three particular histologic features and
exclusion of mimics.
These are: (I) irregularly shaped and positioned glands,
(ii) stroma altered by fibrosis or excessive collagen,
(iii) thick walled blood vessels.
The prevalence of polyps in general population is about 24%. Polyps are
common in women over 40 years of age and extremely rare, before
menarche. The most common presentation is postmenopausal bleeding,
infolder patients and intermenstrual bleeding, in younger patients. A
polyp should always be considered if abnormal bleeding persists after
curettage, because polyps that contain a delicate, pliable stalk may elude
the curette. Polyps are believed commonly to be a risk factor for endometrial cancer ,because hyperplastic and neoplastic lesions, can be found in their context.
In studies, fragmentation of the polyp, incompleteness of the specimen,
and the presence of adjacent endometrium hamper the diagnosis, as to
whether an endometrial cancer has originated in an antecedent benign
polyp or in the surrounding endometrium.11
Glands in polyps often fail to cycle normally, secretory changes may be
weak or absent in contrast to the surrounding endometrium, or the glands
The mesenchymal component of polyps may consist of endometrial
stroma, fibrous tissue, as smooth muscle, but generally the stroma
appears more fibrous, than normal fundus endometrium. Polyps are
morphologically diverse lesions that are difficult to sub classify; but most
can be categorized as; hyperplastic, atrophic or functional.
Hyperplastic polyps contain proliferating, irregularly shaped glands, resembling diffuse, nonpolypoid endometrial hyperplasia probably
etiologically related to hormone imbalances.
Atrophic polyps, consist of low columnar or cuboidal cells lining cystically dilated glands. These polyps are typically found in
postmenopausal patients and may represent regression of hyperplastic or
functional polyps.
Functional polyps, containing glands resembling normally cycling endometrium, are relatively uncommon.
Polyps, may be difficult to recognize in curettage specimens, ideally they
appear as polypoid shaped fragments of tissue with epithelium on three
sides. These criteria may be difficult to apply if lesions are fragmented, or
partially removed. In addition, normal endometrium has an irregular
surface, that may appear as a polypoid fragment with epithelium on three
sides, when sectioned tangentially. Identification of tissue fragments
vessels, that contrast with the appearance of the surrounding
endometrium suggest a polyp.11
Robboy, et al., studied 151 endometrial polyps, and described a new
feature useful in the diagnosis of polyps, namely endometrial glands that grow parallel to each other, with their long axis, parallel to the elongate sides of a pedunculated polyp. Endometrial glands, in their
normal physiological stage, grow with their long axis perpendicular to
the mucosal surface, that lines the endometrial cavity. The parallel
arrangement was more prominentin pedunculated polyps than in sessile polyps, in premenopausal, than in postmenopausal women and in
functional and hyperplastic polyps, than in fibrous polyps.
Savelli, L. et al., studied 358 endometrial polyps, and divided them into
(group A : benign) and ( group B : atypical hyperplastic and cancerous).
Age, menopause status, and hypertension were associated significantly
with group B.
EFFECTS OF TAMOXIFEN ON ENDOMETRIUM :
Tamoxifen, acts as a partial estrogen receptor (ER) antagonist neoplastic
breast tissue and as an agonist for the endometrium. The latter , is widely believed to be responsible for a wide range of glandular and
to carcinosarcoma. Tamoxifen, has also been consistently associated with
an increased incidence of endometrial polyps.
3) ENDOMETRIAL HYPERPLASIA :
Endometrial hyperplasia is defined as a proliferation of glands of
irregular size and shape with an increase in the gland/stroma ratio,
compared with proliferative endometrium. Endometrial hyperplasia,
usually occurs in the perimenopausal or postmenopausal years. It
represents a spectrum of morphologic and biologic alterations of the
endometrial glands and stroma, ranging from an exaggerated physiologic
state to carcinoma in situ.In the past, both generalized hormone
responses and localized premalignant lesions have been dumped under
the term endometrial hyperplasia, subdivided by architectural complexity
and cytologic atypia.
Benign endometrial hyperplasia, as it has been recently termed for those
lesions occurring as a result of hormonal effects of unopposed estrogens, are most frequently encountered around the time of menopause , or postmenopause, when the normal cycle of sequentially
Ovulation does not occur in a postmenopausal women, the estrogen
remains unopposed and proliferation continues. This prolonged
proliferation as a result of anovulation, first gives rise to disordered
proliferative endometrium after a period of about 3 weeks. The serum
level of estrogen is not necessarily raised, although in some
circumstances it may be.
Longer intervals of estrogen stimulation ,cause an even greater
exaggeration of the proliferative phase, with an increasingly irregular
distribution of individually variable endometrial glands, which are
known as benign hyperplasia. Micro infarcts, and estrogen withdrawal are
responsible for symptomatic bleeding. Both mechanisms may be effective
at different times in patients with benign hyperplasia. Patchy stromal
breakdown secondary to estrogen induced micro thrombi can produce
intermittent spotting.
Benign endometrial hyperplasia, is encountered most frequently around
the time of the menopause or post menopause, when the normal cycle of
sequentially regulated estrogen and progesterone is perturbed in tempo
and amount. As the endometrial bulk, increases through proliferation as a
result of unopposed estrogenic stimulation, the bleeding may become
more frequent and almost continuous. The causes of excessive bleeding
thrombosis and this contributes to intermittent bleeding. As the condition
depends upon estrogen stimulation for its development, the fluctuation of
estrogenic support results in irregular episodes of extensive apoptotic
endometrial stromal cells death, and breakdown of the tissue.
Most hyperplasias that occur in menopausal women are associated with
chronic anovulation. Typically postmenopausal women with hyperplasia or carcinoma have moderate or heavy vaginal bleeding ,compared with
atrophic endometrium where there will be only spotting per vaginum.
Most reports provided evidence that 20% - 30% of women with
endometrial hyperplasia characterized by glands , with marked
architectural complexity and crowding, in addition to cytologic atypia, progressed to a pattern that the investigators deemed morphologic
adenocarcinoma.
Once a patient had atypical hyperplasia, no further insight into risk,
was provided by grading the degree of atypia; that is, varying degrees of
cytologic atypia were not reflected in a greater or lesser risk of
adenocarcioma once it was determined that the endometrium was
architecturally complex, and the glands were lined by cytologically
atypical cells. In summary, climacteric and menopausal women with
atypical hyperplasia are usually treated by hysterectomy if they are
GROSS FEATURES :
Hyperplastic endometrium, is not distinctive grossly usually. In
hysterectomy specimens, hyperplasia usually presents a velvety, knobby,
surface of pale, spongy tissue with vague borders. Diffuse thickening is
typical but focal overgrowth may occur and simulate a polyp. There may
be 'foci of hemorrhage' in the areas of breakdown. The volume of tissue
obtained in curetting is usually increased, but it may be quite variable.
HYPERPLASIA WITHOUT CYTOLOGIC ATYPIA : I) Simple hyperplasia :
There is an increased glands/stroma ratio and the glands typically vary in size and shape. The glands are cystically dilated ,with occasional out pouching, surrounded by an abundant cellular stroma; at other times, the
glands are only minimally dilated but focally crowded. The cells lining
the glands are pseudostratified, and columnar with amphophilic
cytoplasm mitotic activity is variable. Cells of hyperplasia lacking
nuclear atypia contain oval, basally oriented bland nuclei with smooth,
uniform contours resembling those in normal proliferative glands. The stromal cells are more densely packed than in proliferative endometrium. The cells retain their spindle shape but are plump with
enlarged nuclei and indistinct cytoplasm. Mitosis in endometrial stromal
cells may be variable but sometimes increased.
With increasing degrees of architectural abnormality, glands become complex and branched with irregular outlines and 'papillary enfolding' into the lumen. In addition, glands becomes crowded with increased
proliferation, compressing the intervening stroma, resulting in
“back-to-back” glandular crowding. Thus complex hyperplasia is composed of
'crowded glands with little intervening stroma';. Usually the glandular outlines are highly complex but at times are tubular. Epithelial
stratification and mitotic activity generally, parallel the architectural
complexity but sometimes they are discordant. Epithelial stratification
,may range from two to four layers, mitotic activity invariable and is
usually less than five mitotic figures per 10 high power fields. The
stromal cells are spindle and become compressed by the glandular
proliferation. In addition to densely packed stromal cells, clusters of
'foamy lipid laden cells' can occur in the stroma of simple and complex
hyperplasias; atypical hyperplasias and well differentiated
adenocarcinoma. Foam cells have small pyknotic nuclei and cytoplasm
that contain lipid droplets but nomucin. The foam cells have been shown
to be histiocytes by immunohistochemistry. These histiocystic cells may
also be observed in atrophic and non neoplastic endometria.The isolated
finding of histiocytes, alone is in postmenopausal women with abnormal
ofhistiocytes containing phagocytosed acute inflammatory cells, or normal endometrial cells in postmenopausal women with abnormal uterine bleeding, has been associated with a three to four fold greater likelihood of coexistent, endometrial carcinoma or hyperplasia.12
ATYPICAL HYPERPLASIAS :
The main feature which differentiates this category, from the previous
one is the atypical cytology of the glandular lining as represented by loss of axial polarity, unusual nuclear shapes that are often rounded, irregularity in the nuclear membranes, prominent nucleoli and cleared or dense chromatin.
Atypia occurs nearly always focally.
1) Simple atypical hyperplasia :
This entity features atypical glandular cytology, superimposed on the
architecture of simple hyperplasia. This pattern is extremely unusual. The
glandular outlines may be relatively simple with minimal complexity or
they may be more irregular with interglandular tufting. They are
separated by abundant stroma; back to back glands are absent.
2) Complex atypical hyperplasia :
The frequently found complex atypical hyperplasia, is a lesion
outgrowths, and cytological atypia. Irregular glandular outlines, back to
back crowding, are seen along with epithelial stratification and variable
mitotic activity, papillary infoldings are also seen. There may be
associated foci of non endometroid differentiation such as squamous
morules. Due to the expansion, and crowding of glands the inter
glandular stroma is diminished, but remains present. Characteristic
features of adenocarcinoma are absent.

Carcinoma of the endometrium, is the most common gynecologic
malignancy in developed countries. It typically occurs in elderly
individuals, 80% of the patients being postmenopausal, at the time of
diagnosis. Given uterine bleeding the probability of carcinoma, is a strong
function of the patients age. The rate is 9% for women in their 50’s; 16%
for those in their60s; 28% for those in their 70s and 60% for those in their
80s.
Patients with endometrial adenocarcinoma fall into two loose
clinicopathologic clusters. Patients in the first group (type I) tend to be between 40 and 60 years of age. These patients may have a history of chronic anovulation or estrogen hormone replacement therapy and the
carcinomas are usually well differentiated, Stage I, non myoinvasive
tumors associated with endometrial hyperplasia. Most of the tumors are
ER and PR positive and p53negative and express low levels of the
proliferation antigen Ki-67. Patients in the first group have a very
favorable prognosis after hysterectomy.
In contrast, patients in the second group (type II) tend to be elderly and ,typically have no history of hyperestrogenism. In these cases the
surrounding on neoplastic endometrium is almost always atrophic and there is often an insitu component with high grade cytologic features. The
carcinomas, that develop in this group of patients are usually of the
neoplasms that are first found with deep myoinvasion. The tumors tend to
be ER/PR negative, strongly expressp53, and show high Ki-67 labelling.1
The most common type, of endometrial carcinomas,
endometroidadenocarcinoma, may be manifested by such clinical
findings as obesity, infertility and late menopause. In particular high
estrone and albumin bound estradiol levels were associated with
increased risk in postmenopausal women than in premenopausal women.
Diabetes has been repeatedly associated with an increased risk of
endometrial cancer ranging from 1.2 to 2.1.14

ENDOMETROID ADENOCARCINOMA :
Endometrioid adenocarcinoma, is defined as a cancer in which the
glandular pattern, when well differentiated, has cytologic features most
like abnormal proliferative endometrium. The most common sub type of
endometrial cancer is endometroid, its pure form constituting about 60%
of all endometrial carcinoma. Most neoplasms develop slowly in the
setting of hyperestrogenism against a background of benign endometrial hyperplasia and, EIN, although some arise in atrophic endometrium. It is
predominantly a disease of sixth and seventh decades and 75% of cases occur after the menopause. Until recent years, the diagnosis has been
play a part. Outpatient endometrial sampling techniques generally have a
good diagnostic rate for endometrial carcinoma.
Morphology :
Endometroid carcinoma can present variously, the uterus may be slightly
or grossly enlarged, but it may be of normal size or even small and
atrophic, particularly in a postmenopausal women. Most of them arise in
the corpus,
presenting either as single mass, or two or three separate masses or a
diffuse thickening of the endometrium. More frequently carcinomas are situated on the posterior wall. The most common appearance is of a raised, rough, perhaps papillary area of the endometrium, with a shaggy
surface and ulceration, frequently occupying at least half of the surface
area of the endometrium. Sometimes the tumor is polypoid with a fairly
narrow base.Myometrial invasion may be obvious to the naked eye, with
either pushing or infiltrating borders, but frequently it is difficult to
appreciate the degree ofmyometrial invasion grossly. A tumor diameter of
more than 2 cm generally, is associated with a poorer prognosis and a
higher frequency of distant failure.
Microscopically, the glandular pattern, and cellular features generally resemble that of the proliferative phase endometrium. Multilayered
Solid growth may vary widely in extent a feature of importance in tumor
grading. Individual epithelial cells are larger than would be expected in
the proliferative phase. The carcinoma cells have a distinctly altered
cytology that varies between patients, and even within areas of a single
tumor, but may include rounded nuclei, clumped chromatin, and
prominent nucleoli. Individual tumors frequently demonstrate patchy
changes, in differentiation to Mucinous, squamous, tubal or other
cytology, and in these cases ,cytoplasmic as well as nuclear features stand
out from the normal background. Some endometroid adenocarcinoma
secrete abundant extracellular mucin but lack much intracytoplasmic
mucin a feature that distinguishes them from mucinous adenocarcinoma.
Mitotic figures are ,usually present but may be scant in well differentiated
tumors.
The endometrial stroma, adjacent to the newly forming well differentiated
neoplastic glands responds by remodeling, rarely demonstrating classic
desmoplastic change. For this reason, qualitatively assessing the character
of the endometrial stroma is non contributory.
Presumptive identification of the earliest stages of endometroid
endometrial (type I) precancers has now been accomplished using a
variety of molecular marker systems, derived from this model. These
include lineage continuity (forward carry over) of mutations of genes

OTHER VARIANTS OF ENDOMETIROID ADENOCARCINOMA :
Four histologic variants of endometrioid adenocarcinoma ,are recognized
which are –
I. Endometrioid adenocarcinoma, with squamous differentiation.
ii. Endometrioid adenocarcinoma, with secretory differentiation.
iii. Endometrioid adenocarcinoma, with ciliated cell differentiation.
iv. Endometrioid adenocarcinoma, with villoglandular variant.
Endometrioid adenocarcinoma with squamous differentiation :
One fourth of endometrial adenocarcinoma display focal
squamousdifferentiation. In the late 1960s the distinction was made
between tumors where the squamous component was ‘well’ or ‘poorly’,
differentiated. The former tumors, were called ‘adenocanthoma’ and the
latter ‘adenosquamous’carcinoma. Numerous studies have confirmed the
significantly better prognosis associated with adenocanthoma, and
endometrial carcinoma without squamous differentiation (about 90%
survival at 5 years) as compared to ,adenosquamous carcinoma (65%), a
distinction related largely to the grade of the glandular component.
so that a solid focus of adenocarcinoma will not be mistaken for
squamous differentiation.
Squamous differentiation is suggested by the presence of any of the following:
o Keratin or Keratin pearls demonstrated without special stains
o Inter cellular bridges
o At least three of the following
Sheet like growth without gland formation or pallisading
Distinct cell margins
Deeply eosinophilic or ‘glassy’ cytoplasm
Decreased nuclear : cytoplasmic ratio compared with the rest
of the tumor.
In large studies where the glandular and squamous components were
graded independently, differentiation of the squamous component was
shown to parallel that of the glandular component closely. Thus, the
prognosis can be predicted by the glandular grade alone. Grading of the
glandular component is also superior in predicting lymph node metastasis
and 5 year survival.
Secretory adenocarcinoma’ are an uncommon variant of endometrioid adenocarcinoma, composed of well differentiated glands resembling the
early or mid-secretory endometrium. The most common changes are sub
nuclear and/or supranuclear vacuolation. In addition, there may be solid
areas, consisting of small polygonal cells with clear cytoplasm. Secretory
adenocarcinomas are associated with a good prognosis. The distinction of
secretory carcinoma from atypical hyperplasia, with secretory effect can
be difficult and is based on the presence of stromal invasion in the
carcinoma.
Endometrial adenocarcinoma, endometrioid type with ciliated cell differentiation :
Ciliated cell carcinoma is a rare form of differentiation in low grade endometrioid carcinoma. It does not need to be classified separately from
endometrioid carcinoma. Patients range in age from 42 to 79 years, are
often, postmenopausal and present with bleeding. Microscopically,
ciliated carcinoma is almost always well-differentiated and often displays
a cribriform pattern. The gland lumens in the cribriform areas ,are lined
by cells with prominent eosinophilic cytoplasm and cilia.
Villoglandular carcinoma is a variant of endometrioid carcinoma that
displays a papillary architecture, in which the papillary fronds are
composed of delicate fibro vascular core, covered by columnar cells that
generally contain bland nuclei. The median age is 61 years, similar to that of women with typical endometrioid carcinoma. The microscopic
appearance of villoglandular carcinoma is, characterized by thin, delicate
fronds covered by stratified columnar epithelial cells with oval nuclei that
generally display mild to moderate ,(grade 1 or 2) atypia. Mitotic activity
is variable. Myometrial invasion is usually superficial. The main
consideration in the differential diagnosis is serous carcinoma, because
both villoglandular and serous carcinoma have a prominent papillary
pattern.
PAPILLARY SEROUS CARCINOMA
Serous adenocarcinoma, is an aggressive form of endometrial cancer
exhibiting a predominantly papillary architecture composed of exfoliative
bullous hobnail like cells with marked nuclear atypia. Serous
adenocarcinoma, is a poor prognostic form of endometrial cancer. It
accounts for 1-10% of all endometrial cancers. Majority of cases have
lymphovascular invasion and deep myometrial invasion and, a higher
incidence of cervical and lower uterine segment involvement. It is

FOR ENDOMETRIAL CARCINOMA :
Stage I : Confined to the uterine corpus
IA : No or less than half of myometrium
IB : Invasion equal to or more than half of the myometrium.

Stage II : Uterine cervix involved
Cervical stromal invasion , but does not extend beyond uterus
Stage III : Pelvic extension
IIIA : Tumor invasion of serosa and/or adnexa .
IIIB : Vaginal / parametrial involvement.
IIIC : Metastases to pelvic and/or para-aortic lymph nodes.

IVA : Tumor invasion of bladder and/or bowel mucosa.
HISTOLOGIC GRADING SYSTEM :1
Degree of architectural differentiation
Grade 1 : 5% or less of a non squamous or non morular solid growth
pattern.
Grade 2 : 6% - 50% of a nonsquamous or non morular solid growth
pattern.
Grade 3 :>50% of a non squamous or non morular solid growth pattern.
NUCLEAR GRADING :
The nuclear grade is determined by the variation in nuclear size, and
shape, chromatin distribution, and size of the nucleoli.
Grade 1 nuclei are oval mildly enlarged and have evenly dispersed
chromatin
Grade 3 nuclei are markedly enlarged and pleomorphic with irregular,
coarse chromatin and prominent esoinophilic nucleoli.
Grade 2 nuclei have features intermediate to grades 1 and 3.
Mitotic activity is an independent histologic variable, but it is generally

out of which majority 8 (47.3%) showed endometrial atrophy followed by
6 (35.2%) cases of malignancies. Majority of malignant cases (64.2%) were found after a duration of menopause of 10 years. This indicates that endometrial malignancies were more likely to occur with prolonged
duration of menopause and increasing age. Majority of Endometrial
adenocarcinoma of endometrioid type were seen within shorter duration
of menopause and lesser age; whereas the variants of endometrial
carcinomas like, serous carcinoma, squamous cell carcinoma were seen
