potential causes

N-ras mutations

epidemiology

risk factors

labimaging

conventional treatment

Prophylactic removal during teen years; staged surgical removals if large

complications

prevention

Need to talk to parents about how size of congenital nevi can affect risk for development of MM; surgical options (staged removals, grafting); monitor CHANGES in lesion
