NCI Definition: A high-grade endometrial adenocarcinoma characterized by the presence of large neoplastic cells that display at least focal cytoplasmic clearing. The neoplastic cells form papillary, glandular, or sheet-like structures. [1]

Endometrial clear cell adenocarcinomas most frequently harbor alterations in TP53, PIK3CA, ARID1A, FBXW7, and KMT2D [2].

Most Commonly Altered Genes in Endometrial Clear Cell Adenocarcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, PIK3CA Mutation, and ARID1A Mutation are the most common alterations in endometrial clear cell adenocarcinoma [2].
