We had access to the Haematoxylin and Eosin (H&E) stain for three of these supra-carcinoids, on which the pathologists discarded misclassifications with LCNEC, SCLC, or mesothelioma in the case of the asbestos-exposed BAP1-mutated sample (Fig. 2c and Table 1). The gene discussed is BAP1; the disease is mesothelioma.
