Melanoma and mesothelioma show a statistically significant co-occurrence in the general population.
Inherited melanoma and mesothelioma predisposition is shown by individual with germline mutations in BAP1.
We report a patient with mesothelioma who carried a germline mutation in CDKN2A, a gene involved in familial melanoma.
This paper suggests that CDKN2A and possibly other genes may also predispose to both these tumors.
It also suggests that mesothelioma and melanoma may share common stepwise carcinogenic pathways.
