A case of hypopigmented mycosis fungoides successfully treated with 311 nm narrowband ultraviolet B phototherapy

Abstract

Hypopigmented mycosis fungoides (HMF) is a rare clinical variant of mycosis fungoides (MF) characterized by hypopigmented lesions involving most commonly trunk and proximal extremities. We report here a case of HMF in 22-year-old Korean woman successfully treated with 311 nm narrow-band ultraviolet B (NB-UVB) phototherapy. She presented with progressive asymptomatic hypopigmented patches on wholebody 1-year ago and diagnosed as HMF based on clinicopathologic findings. She was treated with NB-UVB phototherapy and showed almost complete clearance after 8-month without any side effects.
