Normal chorionic villi products of conception Trophoblastic epithelium

Normal chorionic villi …(products of conception) Trophoblastic epithelium (cytotrophoblasts + syncytiotrophoblasts)

Normal products of conception…high power cytotrophoblasts Hofbauer cell (the macrophage here) syncytiotrophoblast

Fallopian tube lining… Pseudopapillary projections…the lume is irregular…on high power the cells are columnar ciliated Normal fallopian tube

Ectopic tubal pregnancy Fallopian tube lining (fimbriated end) Fibrin (hemorrhage) Chorionic villi

Grape-like Hydatidiform mole Trophoblastic proliferation Swollen (hydropic) chorionic villi with cistern fluid inside

Choriocarcinoma hemorrhage Malignant cytotrophoblasts Malignant syncytiotrophoblasts

-No complexity of epithelial architecture -No significant atypia

Serous cystadenocarcinoma Complexity in epithelium (multilayering) + atypia + stromal invasion

Mucinous cystadenoma Mucinous lining -No complexity of epithelial architecture -No significant atypia

Mucinous cystadenocarcinoma Complexity in epithelium (multilayering) + atypia + stromal invasion

keratin Mature cystic teratoma Squamous epithelium cartilage Fat Sebaceous glands

Granulosa cell tumor The nuclei are grooved (coffee-bean shape) Call exner bodies (follicle-like structures with eosinophilic material inside)
