NCI Definition: A malignant mixed epithelial neoplasm that arises from the ovary and is composed predominantly of serous and endocervical-type mucinous epithelium. [1]

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

Most Commonly Altered Genes in Malignant 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 malignant ovarian mixed epithelial tumor [2].
