Erythema gyratum repens: Another Case of a Rare Disorder but No New Insight into Pathogenesis

Abstract

Erythema gyratum repens (EGR) is an uncommon but distinctive dermatosis characterized by marble-like swirls of erythema and a thin covering scale over the trunk, axillae and groins which has been associated with malignancy. Bronchial carcinoma has been the most frequent neoplasm associated. A case of EGR in a 50-year-old man with carcinoma of the lung is reported. The onset of dermatosis preceded the discovery of the neoplasm by 9 months. Oral corticosteroids induced the disappearance of the skin lesions. No recurrence was observed after discontinuation of the treatment. The patient died 1 year after the onset of dermatosis.
