Abstract

Annular pustular psoriasis is a rare variant of the generalized pustular psoriasis characterized by annular lesions with rapidly evolving pustules, associated mild toxicity, and rapid response to therapy. We present a case of annular pustular psoriasis in a 17-year-old male, in whom no previous history of psoriasis was found. The skin lesions were characterized clinically by annular to gyrate erythematous lesions with pinpoint pustules near the periphery on both shoulders, upper arms, and back areas. The histology showed large intraepidermal spongiform pustules. Most of the skin lesions disappeared within 1 week with topical corticosteroid cream.
