Dermoscopy revealing an amelanotic subungual melanoma masked as contact dermatitis.

Abstract

An otherwise healthy 62-year-old woman presented with an acute itchy eruption on her right (dominant hand) middle finger after using a gel nail. There was a history of nail trauma two years back, following which she observed alterations of the nail plate for which she filed her nail regularly. She used an artificial nail for the same reason and developed skin lesions a few days later. Cutaneous examination revealed erythema, desquamation and yellow to red crusts on the finger tip and periungual region along with small vesicles on the dorsum of the middle finger. There was loss of central part of the nail plate.
