Hereditary melanoma and the dysplastic nevus syndrome: the risk of cancers other than melanoma.

We analyzed the prospective occurrence of cancers other than malignant melanoma in fourteen kindreds with hereditary cutaneous malignant melanoma and the dysplastic nevus syndrome. No significant excess of nonmelanoma cancers was documented, suggesting that hereditary cutaneous malignant melanoma/dysplastic nevus syndrome is not pleiotropic for other tumor types.
