Case report: photo-onycholysis after PUVA treatment for hypopigmented mycosis fungoides with response to topical steroid.

Melanin in the nail bed in patients with skin type VI has been suggested to afford some protection against photo-onycholysis. We report a case of a 16-year-old male patient with skin type VI with onycholysis following PUVA treatment for hypopigmented mycosis fungoides. Symptoms resolved with the application of topical steroid.
