IllnessMelanomas, familial + uveal; differential diagnosis

[Sanger]

Malignant melanoma begins in melanocytes in areas that are only occasionally exposed to the sun as cutaneous melanoma or rarely in other tissues (choroidal or mucosal melanoma), most commonly in the fifties to seventies of life. Melanoma may develop from an existing mole or other normal skin growth, become cancerous in the epidermis and even metastasize. Melanoma is also common in genetic syndromes such as xeroderma pigmentosum, among others. Most familial melanomas are inherited in an autosomal dominant manner. The DNA diagnostic yield is largely unknown. Therefore, an inconspicuous molecular genetic result does not exclude the clinical diagnosis.
