The diagnosis of a single BIMT in a patient does not imply genetic testing for a BAP1‐germline mutation unless multiple BIMT are seen in the same patient or there is clinical suspicion due to a positive family history or manifestation of other tumours, especially uveal melanoma, cutaneous melanoma, mesothelioma and renal cell carcinoma.14 Here, BAP1 is linked to mesothelioma.
