A Rare Case Presentation of Erythema Annulare Centrifugum-Like Acute Psoriasis

Abstract

We report a case of erythema annulare centrifugum-like psoriasis occurring in a 44-year-old female. The patient presented with annular erythematous plaques with trailing collarette scales affecting the elbows and antecubital fossae, which are consistent with a clinical diagnosis of erythema annulare centrifugum (EAC). Given the presence of classical clinical features of EAC, this case was notable due to biopsy findings, which revealed classic histologic changes of psoriasis. This finding supports the diagnosis of erythema annulare centrifugum-like psoriasis and represents a rare presentation of acute psoriasis. Treatment with topical mometasone led to rapid and sustained long-term remission.
