NCI Definition: Malignant mesothelioma that arises from the pleura and is characterized by the presence of cells with epithelioid morphology. The epithelioid cells usually have eosinophilic cytoplasm, bland nuclei, and form tubulopapillary, microglandular, or sheet-like patterns. [1]

Pleural epithelioid mesotheliomas most frequently harbor alterations in BAP1, CDKN2A, NF2, CDKN2B, and SETD2 [2].

Most Commonly Altered Genes in Pleural Epithelioid Mesothelioma

CDKN2A Loss, CDKN2B Loss, BAP1 Mutation, BAP1fs, and NF2 Mutation are the most common alterations in pleural epithelioid mesothelioma [2].
