NCI Definition: A benign, borderline, or malignant epithelial tumor of the ovary characterized by the presence of glands and/or cysts lined by neoplastic cells that resemble endometrial cells. [1]

Ovarian endometrioid tumors most frequently harbor alterations in TP53, PIK3CA, KRAS, PTEN, and ARID1A [2].

Most Commonly Altered Genes in Ovarian Endometrioid Tumor

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, PIK3CA Mutation, and PTEN Mutation are the most common alterations in ovarian endometrioid tumor [2].
