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

Summary 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 .
