1 Ovary
2 Barrett esophagus ph in vagina between 3.8 and 4.5 ph of stomach varies from 1-2 (hydrochloric acid) up to 4-5 BE probably results from upward migration of columnar cells from gastroesophageal junction (GEJ) GEJ cells are also origin of gastric-type metaplasia in distal esophagus It is unclear whether gastric-type metaplasia is a precursor to intestinal type metaplasia or whether they are separate entities
3 Diseases of the ovary nonneoplastic lesions - pelvic inflammatory disease - ovarian cysts - endometriosis ovarian tumors - epithelial (surface epithelial-stromal) - sex cord-stromal - germ cell - germ cell sex-cord stromal
4 Nonneoplastic inclusion functional endometrioid Ovarian cysts Cystic tumors epithelial tumors - cystadenoma (benign, borderline) - cystadenocarcinoma germ cell tumors - dermoid cyst
5 Nonneoplastic cysts inclusion cysts - inclusions of the surface epithelium - inclusions from fimbrial epitehlium functional cysts - follicular cyst - corpus luteum cyst - hemorrhagic cyst endometrioid cyst
6 Nonneoplastic cysts inclusion cysts - inclusions of the surface epithelium - inclusions from fimbrial epitehlium functional cysts - follicular cyst - corpus luteum cyst - hemorrhagic cyst - simple unilocular cysts - up to 1 cm in diameter - larger cyst - cystadenoma endometrioid cyst
7 Nonneoplastic cysts - unilocular thin walled cysts inclusion cysts - more than 3 cm in diameter - inclusions of the surface epithelium - content: serous, serosanguineous, - inclusions from fimbrial epitehlium clotted blood functional cysts - follicular cyst - corpus luteum cyst - hemorrhagic cyst endometrioid cyst
8 Nonneoplastic cysts inclusion cysts - thick and fibrotic wall - up to 15 cm in diameter - cyst content: semifluid, chocolate-colored functional cysts material - inclusions of the surface epithelium - inclusions from fimbrial epitehlium - follicular cyst - corpus luteum cyst - hemorrhagic cyst endometrioid cyst
9 Ovarian tumors
10 Classification of ovarian tumors epithelial tumors sex cord-stromal tumors germ cell tumors germ cell sex cord-stromal tumors
11 Classification of epithelial tumors according to their gross features: - cystadenoma (cystadenocarcinoma) - cystadenofibroma - adenofibroma (adenocarcinofibroma) - surface papilloma (surface papillary carcinoma) according to their histogenesis
12 Classification of epithelial tumors according to their gross features: - cystadenoma (cystadenocarcinoma) - cystadenofibroma - adenofibroma (adenocarcinofibroma) - surface papilloma (surface papillary carcinoma) according to their histogenesis!!!
13 Epithelial tumors benign borderline malignant serous - low grade - high grade endometrioid clear cell mucinous
14 Surface epithelial tumors benign borderline Tumors of müllerian origin malignant Müllerian (paramesonephric) ducts will give rise to: - upper vagina - cervix - uterus - Fallopian tube serous - low grade - high grade endometrioid clear cell mucinous
15 Benign epithelial tumors can be large (especially mucinous tumors the world s biggest tumor weighted 136 kilos) symptoms and signs usually nonspecific: - pelvic pain - discomfort - an asymptomatic pelvic mass up to 25% of tumors bilateral
16 Benign serous cystadenoma
17
18 Benign mucinous cystadenoma
19 Borderline tumors increased epithelial proliferation do not display invasion usually behave in a benign fashion but behavior can be malignant clinical features similar to those for benign tumors
20 Serous borderline tumor
21 Serous borderline tumor
22 Borderline tumor vs. carcinoma Borderline tumor Median age % of tumor in stage I 5-year survival % % rate for stage I 5-year survival % % rate for stage II 5-year survival % % rate for stage III metastatic spread rare common Invasive caricnoma
23 Ovarian cancer about 30% of all cancers of the female genital tract incidence rates are highest in the economically advanced countries (most frequent cause of death due to gynecological cancer) epithelial carcinomas account for 90% of these cancers in North America and Western Europe in some Asian countries, including Japan, germ cell tumours account for a significant proportion (20%) of ovarian malignancies
24 Risk factors age reproductive factors - early menarche, late menopause high socioeconomic status - lower fertility BRCA1/2 mutation (5-10% hereditary) Ovarian cancer Protective factors increased parity oral contraceptive use surgically induced: - hysterectomy - tubal ligation - bilateral salpingooophorectomy
