Polycystic-ovary syndrome
What is the most common ovarian epithelial tumor generally occurring under 40 years of age?
Serous cystadenomas
What is a general condition of the endomterium which is believed to be a precancerous condition, occurs aounrd the time of or after menopause and thought to be a precursor of endometrial carcinoma?
Endometrial Hyperplasia
Leiomyosarcoma
it gives you the opportunity to looks at colonic glands, at the bottom of the image, versus endometrial glands, at the top of the image

Microscopically you will see a hyperplastic polyp which contain dilated cystic glands. The dilated cystic glands are more common; In rare cases, adenocarcinoma may develop in the polyp
Thecoma
What is psuedomyxoma peritonei? How can this affect the GIT?
The flood of mucus in the peritoneal cavity; It can cause bowel obstruction

peritoneal cavity; 85% are benign, 10% of borderline and 5% are invasive
Endometrial adenocarcinoma usually occurs in what age group? What are risk factors for adenocarcinoma?(2-4 points)
post-menopausal women; obesity, hypertension, nulliparity and diabetes
Firm, white tumors made up of fibroconnective tissue in the female genital tract? It is a germ cell tumor.
fibromas
Proliferative Stage of Menstrual Cycle

endometriosis
What are variants of endometrial adenocarcinoma?(1-3 points)
Clear Cell Carcinoma, papillary serous carcinoma and mucinous carcinoma
The most common is dysfunctional uterine bleeding, seen here as anovulatory endomertium with stromal breakdown
Chronic endometritis is associated with what conditions?**(2-4points) **What type of cellular features do you find in the stroma of the endometrium?
rentention of products of conception, TB, IUD and pelvic inflammtory disease; you find plasma cells in the stroma
What are the four categories of ovarian tumors?**(4 points) **Which one is the most common?
Epithelial, germ cell, gonadal and metastatic; epithelial

The upper right picture is Grade I
The picture to the lower left is Grade II
The picture to the lower right is Grade III
Granulosa Cell Tumor
PAPILLARY SEROUS CYSTADENOMA
What is the relative percentage of cases of endometrial tumors that are associated with endometriosis? Are most endometroid tumors carcinomas?
Low percentage; about 15-20%; yes
Endometrial Polyp
Granulosa Cell Tumor
What is often seen in post-menopausal period and typically present with bleeding?
Endometrial polyps
What is the most common malignant tumor of the female genital tract? What is the pathogenesis of this disease?(3 points)
Endometrial Adenocarcinoma; there is prolonged unopposed estrogen stimulation of the endometrium leading to hyperplasia resulting in adenocarcinoma
Anovulatory Endometrium
Most Brenner Tumors are benign or malignant? What is the histological description of the cells in Brenner Tumors?(3 points)
most are benign; the cells nest with cells resembling transitional cells embedded in abundant stroma
Type I Endometrial Carcinoma
here is a papillary lesion going into the endometrial cavity.
Type II tends to be more common in African American Woman. The statistics changes, she is going to ask us worsens that don’t change at all over time. We should be able to figure out benign from malignant.
She wants to make sure we understand staging determines prognosis.
