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 TP53, PIK3CA, KRAS, and KMT2D [2].

Most Commonly Altered Genes in Ovarian Seromucinous Carcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, PIK3CA Mutation, and KRAS Mutation are the most common alterations in ovarian seromucinous carcinoma [2].
