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

Ovarian seromucinous carcinomas most frequently harbor alterations in KRAS, TP53, SRSF2, PIK3CA, and CDKN2A [2].

Most Commonly Altered Genes in Ovarian Seromucinous Carcinoma

KRAS Mutation, KRAS Exon 2 Mutation, KRAS Codon 12 Missense, TP53 Mutation, and PIK3CA Mutation are the most common alterations in ovarian seromucinous carcinoma [2].
