NCI Definition: A benign, borderline, or malignant mixed epithelial tumor of the ovary. It is characterized by the presence of more than one epithelial cell type, most often serous and endocervical-type mucinous. [1]

Ovarian mixed epithelial tumors most frequently harbor alterations in TP53, KRAS, PIK3CA, NF1, and KMT2D [2].

Most Commonly Altered Genes in Ovarian Mixed Epithelial Tumor

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, KRAS Mutation, and KRAS Exon 2 Mutation are the most common alterations in ovarian mixed epithelial tumor [2].
