A combination of mtap and bap1 immunohistochemistry in pleural effusion cytology for the diagnosis of mesothelioma. Tumor tissue showed loss of bap1 nuclear expression by immunohistochemistry. Loss of one or the other marker was observed in 17/20. Histologic variants (epithelioid, biphasic and sarcomatoid) impart prognostic information with treatment implications. Criteria for diagnosis of mesothelioma will also be reviewed and discussed. The distinction between malignant mesothelioma and reactive mesothelial proliferation can be challenging both on histology and cytology. We validated this using immunohistochemical (ihc) staining demonstrating a lack of bap1 nuclear staining in the tumors with bap1 homozygous deletion (fig. immunohistochemistry (ihc) is a reliable technique to determine bap1 molecular status. immunohistochemistry in patients with mesothelioma, validating loss of expression in independent international cohorts.
