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

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

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

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

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

7. Choriocarcinoma hemorrhage Malignant cytotrophoblasts
Malignant syncytiotrophoblasts

8. -No complexity of epithelial architecture
-No significant atypia

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

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

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

12. keratin
Mature cystic teratoma
Squamous epithelium
cartilage
cartilage

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