Malignant mesothelioma (MM) is a diagnostically challenging entity in cytology specimens due to the lack of architectural context and a cytomorphologic overlap between malignant and reactive mesothelial cells (RMCs). A diagnostic marker with excellent specificity is not currently available in clinical practice. The newly appreciated BRCA1‐associated protein 1 (BAP1) antibody may help distinguish MM from RMC based on its immunohistochemical (IHC) staining pattern but its role in cytopathology is controversial.
