Overview

NCI Definition: An infiltrating malignant tumor characterized by the presence of atypical cells with myoepithelial differentiation. Representative examples include malignant breast myoepithelioma and salivary gland myoepithelial carcinoma. [1]

Malignant myoepitheliomas most frequently harbor alterations in CDKN2A, EWSR1, TP53, SMARCB1, and CDKN2B [2].

Most Commonly Altered Genes in Malignant Myoepithelioma

EWSR1 Fusion, CDKN2B Loss, CDKN2A Loss, TP53 c.217-c.1178 Missense, and TP53 Mutation are the most common alterations in malignant myoepithelioma [2].
