  • Epithelial ovarian cancer

  • Sex cord stromal tumors

  • Germ cell tumors

  • Metastatic tumors

Twenty to twenty five percent of all ovarian tumors are malignant.

Epithelial Ovarian Cancer

Epithelial cell neoplasms account for 50–55 % of all ovarian tumors. There are benign, “borderline tumors” (of borderline malignancy or low malignant potential), and malignant forms. Malignant epithelial tumors are called carcinoma and constitute approximately 90 % of all ovarian cancers. The vast majority of ovarian carcinomas are adenocarcinoma, i.e., derived from a glandular epithelium. Primary squamous cell carcinoma of the ovary is extremely rare.

Traditionally, it is thought that epithelial neoplasms originate from the ovarian surface epithelium, which is in continuation with and similar to the...
