Atypical mole syndrome: a brief overview for the primary care physician.

Early detection of melanoma and identification of potential markers or precursor lesions can substantially improve survival. Several risk factors have been identified in the pathogenesis of this potentially lethal cancer. Numerous reports in the literature have confirmed a subset of persons with an increased risk of developing melanoma. These patients are identified by a distinctive clinical phenotype depicted by unusually appearing melanocytic nevi (moles) in association with an increased number of total body nevi. They may have a family history of atypical moles or melanoma. In order to facilitate the recognition of such individuals by the non-dermatologist, a brief overview and salient features of the atypical mole syndrome are presented.
