Trophoblastic epithelium (cytotrophoblasts + syncytiotrophoblasts) Normal chorionic villi …(products of conception)
Normal products of conception…high power cytotrophoblasts Hofbauer cell (the macrophage here) syncytiotrophoblast
Fallopian tube lining… Pseudopapillary projections…the lumen 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
Hydatidiform mole Grape-like 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 cartilage Fat Sebaceous glands
Granulosa cell tumor The nuclei are grooved (coffee-bean shape) Call exner bodies (follicle-like structures with eosinophilic material inside)
