Abstract
Nickel stands as one of the prevalent contact allergens, but acquired nail hypertrophy presenting as ACD due to nickel exposure is infrequent. Here we report a case of acquired nail hypertrophy stemming from ACD due to nickel, displaying an uneven coloration, along with nail grooves, deck distortion damage, small surface pits and ecchymosis beneath the damaged deck. The patient limited nickel contact and recovered after 11 months of follow-up.
