Mohs micrographic surgery (MMS) with MART-1 immunostaining for atypical intraepidermal melanocytic proliferation (AIMP)

Surgical outcomes for AIMP are unknown. Upstaging to unequivocal melanoma was identified in 18.8% of AIMP. No local recurrences occurred with a mean follow-up of 2.7 years. 23.8% of AIMP required greater than one stage of MMS. MMS may be an effective treatment option for AIMP.
