Shoulders, Upper chest, and Back
What benign melanocytic neoplasm forms as the coalescence of multiple, irregular peripheral macules
Becker’s Nevi
True/False: Beckerﾒs nevi cause localized loss of hair
False - hair develops both within and close to the nevi
True/False: Only familial atypical melanocytic nevi mark an increase in melanoma risk
False - sporadic disease also shows it
What is the initial management of an atypical melanocytic nevus?
