Endometroid tumors are mainly characterized by phosphatase and tensin homolog (PTEN) and catenin beta 1 (CTNNB1) mutations [2,3,4,5], whereas mucinous tumors display a high-degree of tumor protein P53 (TP53) mutations (52%) [6,7,8] and additional mutations in Kirsten rat sarcoma viral oncogene homolog (KRAS), serine/threonine protein kinase B-Raf (BRAF), and cyclin-dependent kinase inhibitor 2A (CDKN2A). Here, BRAF is linked to mucinous neoplasm.
