What are endometriod tumors?

➢ These tumors may be solid or cystic; ➢ They sometimes develop in association with endometriosis. ➢ On microscopic examination, they are distinguished by the formation of tubular glands, similar to those of the endometrium,within the lining of cystic spaces. ➢ Although benign andborderline forms exist, endometrioid tumors usually are malignant. ➢ They are bilateral in about 30% of cases, and 15% to 30% of women with these ovarian tumors have a concomitant endometrial carcinoma. ➢ Similar to endometrioid-type carcinoma of the endometrium, endometrioid carcinomas of the ovary frequently have mutations in the PTEN tumor suppressor gene as well as mutations in other genes
