Treatment of nail lichen planus with localized bath‐PUVA

Lichen planus (LP) is an inflammatory condition usually involving the skin, hair, and mucous membranes. Nail involvement is present in 10-25% of patients and it is a diagnostic and therapeutic challenge. A 52-year-old female, Fitzpatrick skin type III, diagnosed of dyslipidemia and alopecia areata twenty years earlier, treated with intralesional corticosteroids, presented to our Phototherapy Unit with nail lesions in her finger and toe nails for the last 12 years. No other cutaneous lesions were present.
