Abstract

Nail apparatus melanoma (or subungual melanoma) is rare and accounts for only 1.4% of all cutaneous melanomas in the United Kingdom. We report the use of fixed-tissue Mohs micrographic surgery to treat a biopsy-proven Clark level I in situ nail apparatus melanoma, presenting with diffuse longitudinal melanonychia.
