It shows an activated mitogen-activated protein kinase pathway with KRAS and BRAF mutations and only rarely TP53 mutations, and is a distinct entity from high-grade serous ovarian carcinoma rather than a grade of it. It accounts for 2-5% of ovarian carcinomas and 5-10% of serous ovarian carcinomas. ovarian low-grade serous adenocarcinoma NCIT:C105556 LGSOC
