NCI Definition: An invasive adenocarcinoma composed of malignant glandular cells which contain intracytoplasmic mucin. Often, the infiltrating glandular structures are associated with mucoid stromal formation. It may arise from the large and small intestine, appendix, stomach, lung, ovary, breast, corpus uteri, cervix, vagina, and salivary gland. [1]

Mucinous adenocarcinomas most frequently harbor alterations in KRAS, TP53, GNAS, APC, and SMAD4 [2].

Most Commonly Altered Genes in Mucinous Adenocarcinoma

KRAS Mutation, KRAS Exon 2 Mutation, KRAS Codon 12 Missense, TP53 Mutation, and TP53 Missense are the most common alterations in mucinous adenocarcinoma [2].
