A case of generalized lichen nitidus successfully treated with narrow-band ultraviolet B treatment.

ABSTRACT

Lichen nitidus (LN) is a rare skin disorder presenting with multiple, small and bright papules located on the chest, abdomen, penis glans and upper extremities. It usually presents with limited involvement; however, it can present as generalized involvement. There is no consensus on treatment. Corticosteroid, astemizole, phototherapy has been used; however, the results are controversial. A 15-year-old male with clinical and histopathological diagnosis of LN was treated with narrow-band ultraviolet B (NB-UVB). The lesions completely regressed with post-inflammatory hypopigmentation on the second month of the therapy (25 sessions). We believe that NB-UVB is an effective treatment on generalized LN.
