A Case of Psoriasis After Narrow Band UVB (NBUVB) Phototherapy for Vitiligo Treatment

Abstract

Phototherapy methods commonly used in the treatment of vitiligo include narrow-band ultraviolet B (NB-UVB). A 23-years old male was diagnosed with vitiligo in the dermatology polyclinic and was followed up in the phototherapy unit with NB-UVB treatment of 3 sessions per week; in the 42nd session psoriasis plaques were seen to have developed. We suggest that this rare but important association should be considered as a side effect of narrow-band phototherapy.
