Psoriasis is a disease that at times can take on unusual clinical forms. This is the report of a patient with a rare variant of annular pustular psoriasis in which the lesions have the configuration of erythema annulare centrifugum and resemble subcorneal pustular dermatosis. This rare variant is characterized by rapid evolution, mild toxicity, and rapid response to therapy. Classical lesions of psoriasis can be lacking, and the diagnosis may rest on the clinical course and histologic findings.
