PATHOLOGY OF FALLOPIAN TUBES

Congenital Anomalies Parametritis/Salphingitis Ectopic pregnancy Hydrosalpinx Endometriosis Para ovarian cyst Carcinoma

6

Ectopic Pregnancy:

Tubal – common. implantation allows

early placental development, secretion of hCG, and maintainance of the corpus luteum.

Clinically features of a normal pregnancy and the embryo may also complete the early embryonic stages of development.

Pathology of Ovary

Inflam/Infections - rare Ovarian cysts - common.

Non-Neoplastic▪ Follicular, epithelial, Luteal, etc.▪ Polycystic ovary syndrome▪ Ovarian Hyperstimulation synd.▪ Stromal Hyperplasia*▪ Endometriosis

Neoplasms▪ Benign (Cysts)▪ Malignant (Solid)

OV. NEOPLASMA Serous cystadenoma Cystoma Papillary cystadenoma serosum Surface papilloma Serous adenofibroma Serous cystadenofibroma Pseudomucinous cystadenoma Teratoma

- dermoid cyst- Solid teratoma.

OV. NEOPLASMA Granulosa cell tumor Theca cell tumor Arrhenoblastoma Adrenal rest tumor Dysgerminoma Brenner tumor Fibroma Meigs syndrome Sarcoma Carcinoma (ad.Carcinoma) Metastase carcinoma.

Ovary:

Cysts – Common – benign very large. Solid – rare – malignant – high mortality. 5th common cause of female cancer. But carcinomas of the ovaries account for

more deaths than do cancers of all other female malignancies together. (US stat).

Nulliparity & family history (BRCA) - Risk factor.

Polycystic Ovary Synd Amenorrhoea, hyperoestrogenism

and multiple follicular cysts. Stromal hyperplasia &

anovovulation Important cause of infertility, Endometrial

hyperplasia/Carcinoma. Clinical features:

Acne, alopecia, hirsutism, Hypertension, Insulin resistance, Type 2 DM. Obesity – Syndrome X.

11

PCOS- Low power view

12

Note: capsule thickening, cystic follicles without ova, thecal hyperplasia.

Endometriosis: chocolate cysts Metastases of hyperplastic

endometrium into ovary. Retrograde

menstruation /Metaplasia. Estrogen related. Pouch of Douglas, the

pelvic peritoneum and the ovary - 'chocolate cysts'.

Periodic Pain, pelvic inflammation, infertility.

Endometriosis:Chocolate Cysts

Endometriosis:

15

Chocolate Cysts

Neoplasms of Ovary

Common, produce estrogen. 80% are benign, cystic, young (20-45) 20% are Malignant, solid - older (>40) 6% of all cancers in women. 50% deaths due to late detection. The rule:

Cystic tumors are commonly benign

Solid tumors are commonly malignant.16

Risk Factors

Less clear than other Null parity Gonadal Dysgenesis Family History Ovarian cancer genes

BRCA1 (17q12) & BRCA2(13q12)

Classification of Ovarian Tumours

Epithelial tumors Coelomic mesothelium

Serous (tubal) Mucinous (Cx) Endometrioid (End) Transitional (UT)

90% of malignant tumors of ovary Morphologically

Cystic – Cystadenomas - Benign Solid/cystic – Cystadenoma - Borderline. Solid –Cystadenocarcinoma – Malignant.

19

Serous Tumors

Frequently bilateral (30-66%). 75% benign/bord., 25% malignant. One or few cysts, papillary/solid. Tall columnar ciliated epithelium. Papillary, solid, hemorrhage, necrosis or

adhesions – malignancy. Extension to peritoneum – bad prog.

20

Mucinous Tumors

Less common 25%, very large. Rarely malignant - 15%. Multiloculated, many small cysts. Rarely bilateral – 5-20%. Tall columnar, apical mucin. Pseudomyxoma peritonei.

21

22

Serous Cystadenoma

23

Serous Cystadenoma

24

Serous Cystadenoma

Borderline / Intermediate grade: note larger papillary growth.

25

Serous Cystadenoma

multiloculated, 24cm cystic ovary with attached fallopian tube and uterus. – benign serous cystadenoma.

26

Mucinous Cystadenoma

Note: papillary growths on inner surface

27

Mucinous Cystadenoma

Note: Multi-loculated cystic tumor with some cysts showing hemorrhage.

28

Serous - Cystadenoma - Mucinous

Cuboidal simple – Columnar Mucous

29

Serous Cystadeno-carcinoma

High grade: note large papillary growth extending and covering the cyst.

30

Serous Cystadenoma Borderline

High grade: note large papillary growth extending and covering the cyst.

31

Papillary cystadenoma (bor)

32

Papillary serous cystadenoma (solid/cystic)

33

Serous Cystadeno-carcinoma

High grade: note large papillary growth extending and covering the cyst.

34

Papillary cystadenoma (bor)

Infiltration

Papillary projections

35

Serous cystadeno Ca – bilateral

36

Serous cystadeno Ca.

Solid tumor with atypical cells forming sheets and gland like structures without stroma. (back to back arrangement of

glands)

Germ cell Tumors:

Teratoma – Benign cystic (dermoid cyst) Solid immature Monodermal – struma ovarii, carcinoid

DysgerminomaYolksac tumorMixed germ cell tumor

Dermoid Cyst:

Black arrow: Stratified squamous Keratinizing epithelium. Blue arrow: Abundant sebaceous glands.

45

Immature/Malignant teratoma:

46

Immature/Malignant teratoma:

Any type of carcinoma, sarcoma or germ cell malignancy.

47

Staging of Ovarian Ca:

Complications of Dermoid cyst Torsion - infarction, perforation,

hemoperitoneum, and autoamputation

Bacterial infection of the cyst Perforation - sudden acute

abdomen, Slow granulomatous peritonitis

Hemolytic anemia – clears after removal.

<5% malignancy – Sq. carcinoma. 48

Other Tumors of Ovary:

Endometrioid Ca:

51

Granulosa Cell Tumor:

52

Ovary: Dysgerminoma

53

Ovary: Dysgerminoma

• Teenage / young, 2% of ovarian neoplasms.• 1/2 of malignant germ cell neoplasms• Gonadal dysgenesis – risk factor.

54

Ovary: Dysgerminoma

Note the pale brown appearance of the parenchyma, along with some central collagenous scar. The gross and microscopic appearance of an ovarian dysgerminoma is essentially same as a seminoma of the testis in a male.

55

Granulosa Cell Tumor:

56

Granulosa Cell Tumor:

Steroid cell tumour of the ovary. A well-circumscribed benign ovarian stromal tumour that caused virilisation in the patient

57

Krukenberg Tumor

Metastases of adenocarcinoma to ovary.
