Hey shgrdii, how are you doing?
All patients diagnosed with 1 or more ams should undergo a complete cutaneous examination. Patients with ams should avoid excessive sun exposure and routinely use a sunscreen with a sun protective factor of 15 or greater.
In 1820, norris proposed an association between nevi and melanoma. He described a family in which 2 members developed melanoma, while other family members had "many moles on various parts of their bodies."
however, the exact appearance of these lesions is unknown. The national institute of health consensus conference on the diagnosis and treatment of early melanoma defined a syndrome of familial atypical mole and melanoma (famm).
The criteria of famm syndrome are as follows: (1) the occurrence of malignant melanoma in 1 or more first- or second-degree relatives; (2) the presence of numerous (often >50) melanocytic nevi, some of which are clinically atypical; and (3) many of the associated nevi show certain histologic features.
Patients with famm syndrome should have a complete cutaneous examination performed at the first office visit and then at least every 12 months for life. An individual with an isolated am has little risk of developing a melanoma and should not be identified as melanoma prone.
