Fallopian tube/ovary pathology Flashcards

Fallopian tube

Chronic Salpingitis

Tubal invasive serous carcinoma


Types of Ovarian Surface Epithelial Tumors
Serous
Mucinous
Endometrioid
Clear cell tumors
Brenner tumor
Cystadenofibroma
Are ovariant carcinomas sporadic or familial?
What age do ovarian surface epithelial tumors occur in?
Majority are sporadic/de novo
Only about 10% are familial/inherited
2/3 in reproductive age (80-90% in 20-65 years)
What are some risk factors for surface epithelial neoplasms?
Increased risk: obesity, estrogen usage for >10 years, family history, germ line mutation in tumor suppressor genes
Reduced risk: high parity and use of oral contraceptives

Ovarian surface neoplasm types
Benign – usually cystic (cystadenoma, cystadenofibroma)
Borderline – low malignant potential, solid/cystic
Malignant – solid cystic, 90% of ovarian malignancy

High grade serous carcinoma – TP53 mutation
Most common ovarian epithelial tumors
60% benign, bilateral 25%, borderline 15%, malignant 25%

Low grade serous carcinoma
KRAS, BRAF or ERBB2 mutations

Serous Borderline Tumor

Mucinous Tumors
80% benign
10% borderline
10% malignant
Multicystic, lined by mucin secreting cells
Mostly unilateral
Bilateral = metastasis until proven otherwise

Endometrioid Tumors
Solid/cystic
May be associated with endometriosis
Usually malignant
Bilateral 30%
Concurrent endometrial carcinoma 15-30%
Mutation of PTEN suppressor gene

Uncommon, solid
Usually unilateral
Incidental findings mostly with mucinous tumors
Nests of transitional type epithelium
Mostly benign
Borderline and malignant exist

High grade serous carcinoma – Solid

High grade serous carcinoma – Papillary
Germ Cell Tumors
15-20% of ovarian tumors
younger age group
2-3% malignant = teratoma, dysgerminoma, yolk sak tumor, choriocarcinoma

Mature Cycstic Teratoma

Sex Cord-Stromal Tumors
8% of ovarian tumors
Composed of sex cord derivatives (granuloas and sertoli) and stromal derivatives (theca, lutein, Leydig cell)
Most common = Thecoma, fibroma, granulosa cell tumors

Granulosa Cell Tumor
Can occur at any age (usually postmenopausal)
Granulosa cells in cords, sheets, strands
Mixture of lipid laden theca cells
Can mimic follicles – Call-Exner bodies
Usually estrogenic –> endometrial hyperplasia

Metastasis from primary breast tumor
