B8-026 Pathology of the Ovaries Flashcards
mutations commonly associated with progression of ovarian epithelial tumors [3]
KRAF
BRAF
ERBB2
(high grade serous cysts have BRCA1/2 and Tp53 mutations)
benign
most common ovarian neoplasm
lined by fallopian tube-like epithelium (cilia)
serous cystadenoma
most common malignant tumor of ovary
serous carcinoma
invasion and papillary growth
psammoma bodies
p53 mutation
serous carcinoma
benign
multiloculated, large cyst
lined by mucus-secreting columnar epithelium
mucinous cystadenoma
malignant cyst
rare
may be metastatic from appendiceal or other GI tumors
mucinous carcinoma
presents with expansive or infiltrative pattern
(expansive is lower right image)
mucinous carcinoma
composed of endometrial-type cells, similar morphology to endometrioid carcinoma of endometrium
endometrioid adenocarcinoma
epithelial tumor associated with endometriosis, hypercalcemia and vascular thrombotic events
clear cell carcinoma
involvement of the ovaries but appendiceal mucinous neoplasm can result in
psuedomyxoma peritonei “jelly belly”
benign
most common ovarian tumor in young females
AKA dermoid cyst
mature teratoma
cystic mass with elements from all 3 germ layers
mature teratoma
thyroid tissue in dermoid cyst can cause
hyperthyroidism (struma ovarii)
mature teratoma with malignant transformation can result in [2]
squamous cell carcinoma
adenocarcinoma
malignant, aggressive germ cell tumor
contains fetal tissue and neuroepithelium
immature teratoma
