Classification (WHO)

I - Ovarian epithelial tumors (Surface epithelial-stromal tumors )

  • squamous cell tumors
  • epithelial-stromal tumors (mixed epithelial tumors )
  • Undifferentiated / unclassified epithelial tumors
    • adenocarcinoma (NOS)
    • undifferentiated carcinoma

II - ovarian sex cord-stromal tumors

  • Sex cord-stromal tumors of mixed or unclassified cell types
    • Sex cord tumor with annular tubules
    • Gynandroblastoma
    • Sex cord-stromal tumor, unclassified, NOS
  • Steroid cell tumors
    • Stromal luteoma
    • Leydig cell tumor
      • Leydig cell tumor, Hilus cell tumor type
      • Leydig cell tumor, non-hilar type
      • Leydig cell tumor, NOS
    • Steroid (lipid) cell tumors NOS
      • Well differentiated
      • Malignant

  • Teratoma :
    • Immature
    • Mature
      • Solid
      • Cystic (dermoid cyst )
