  1. Serous
    -benign
    -borderline
    -malignant
    • Surface epithelial-stromal tumor
    • Most common
    • Lined with tall, columnar cells
    • 20-45yrs
    • Benign - cystic smooth
    • Borderline - papillary projections, psamomma
    • Malignant - multifocal, psamomma, invasion
  2. Mucinous
    -benign
    -borderline
    -malignant
    • Surface epithelial-stromal tumor
    • Middle adults
    • KRAS
    • Mucin filled cysts "sandy/gooey"
  3. Endometrioid
    -benign
    -borderline
    -malignant
    • Surface epithelial-stromal tumor
    • Mostly carcinomas
    • Solid and cystic areas
    • Tubular glands like endometrium
  4. Clear Cell
    -benign
    -borderline
    -malignant
    • Surface epithelial-stromal tumor
    • Rare
    • Large epithelial cells with abundant clear cytoplasm
  5. Benign transitional cell tumor - Brenner
    • Surface epithelial-stromal tumor
    • Rare adenofibromas
    • Combo of cystic and solid areas
    • Coffee bean nuclei
  6. Granulosa-Theca Cell Tumor
    • Sex cord-stromal tumor
    • Mostly postmenopausal
    • Coffee bean nuclei, solid sheet of cells
    • Elevated inhibin
  7. Fibroma
    • Sex cord-stromal tumor
    • Fibroblasts
    • Unilateral, encapsulated, hard
    • Hormonally active
  8. Thecoma
    • Sex cord-stromal tumor
    • Plump spindle cells with lipid
    • Unilateral, encapsulated, hard
  9. Sertoli Cell/Leydig cell tumor
    • Sex cord-stromal tumor
    • Pts 10-30
    • Leydig = big, pink
    • Sertoli = dark, blue
    • Masculinization effects (rarely estrogenic)
    • Well-diff tubules
  10. Other rare sex cord tumors
    -Leydig cell/Hilus cell
    -Pregnancy luteoma
    -Gonadoblastoma
    • -Leydig cells with reinke crystalloids, elevated 17-ketosteroids
    • -Pg luteoma - virilization
    • -Gonadoblastoma - abnl sexual dev
  11. Teratoma
    -Mature benign
    -Monodermal (specialized)
    -Immature
    • Mature: reproductive years, paraneoplastic, dermoid cysts, hair, teeth...
    • Monodermal: struma ovarii (thyroid tissue) or carcinoid (intestinal tissue)
    • Immature: average age=18, necrosis, hemorrhage, hair and bone and immature neural elements
  12. Dysgerminoma
    • Germ cell tumor
    • High HCG
    • Sheets of large vesicular cells, fibrous cord, lympho-plasmacytic infiltrate, granulomas
    • Malignant
    • Responsive to chemo
  13. Yolk sac tumor
    • Endodermal sinus is most common
    • High alpha-fetoprotein
    • Schiller Duval bodies
    • Young pts
  14. Metastatic
    • Most often from GI (colonic, appendiceal, gastric)
    • Most often asked about - breast
  15. Choriocarcinoma
    • Germ cell tumor
    • High HCG
    • Placental origin with synciotrophs and cytotrophobolasts
