PUVA-treated pityriasis lichenoides et varioliformis acuta (PLEVA) showing atypical clinical features

We report a patient with pityriasis lichenoides et varioliformis acuta (PLEVA) with atypical clinical features, which was treated successfully with PUVA therapy. A 23-year-old man had discrete multiple erythematous scaly papules and patches on the trunk and extremities. New lesions developed abruptly within 1 month, forming generalized annular erythematous plaques with yellowish scales on the border. Skin biopsy specimens showed the typical histopathological findings of PLEVA. The skin lesions completely resolved with 8 months of PUVA therapy.
