Erythema gyratum repens with pulmonary tuberculosis.
A 63-year-old man presented with erythema gyratum repens of 7 months' duration. A cavitating mass at the right lung apex was resected and proved to be tuberculous. Following the resection, the skin lesions cleared within a few days. Erythema gyratum repens has not previously been described in association with non-malignant visceral pathology. The pathogenesis remains obscure but cannot be related specifically to a response to tumour cells or their products in view of the association reported here. The condition bears no resemblance to any known tuberculide.
