A Case of Plantar Erythema Nodosum / 대한피부과학회지

ABSTRACT

Erythema nodosum is a reactive dermatosis that occurs in response to various stimuli, such as bacterial, fungal and viral infections, drugs and malignancies. Lesions of erythema nodosum usually appear symmetrically on the extensor aspects of the legs with occasional involvement of the thighs or forearms. Unilateral or plantar involvement uncommonly occurs. A 26-year-old man presented with bilateral, painful, multiple, confluent, erythematous, firm nodules confined to the both plantar skin for 7 days. Histopathologic examination revealed fibrosis of and a lymphohistiocytic infiltrate within the septae of fat lobules, consistent with erythema nodosum. We, herein, report an unusual case of plantar erythema nodosum, which was successfully treated with nonsteroidal antiinflammatory drugs for 2 weeks.
