Median canaliform dystrophy of Heller after cryotherapy

Abstract

Cryotherapy, widely used in the treatment of common warts, can cause long-term side effects when used in the treatment of warts near the nail bed. Here we present the case of a 11-year-old girl who developed canaliform dystrophy and long-term hypopigmentation following cryotherapy of warts on the proximal nail folds.
