A 69-year-old man with erythema nodosum migrans manifesting one centrifugally spreading, slightly elevated erythematous plaque on the right lower leg is reported. He was initially diagnosed and treated as cellulites with poor clinical response. A biopsy specimen from this lesion showed classic features of erythema nodosum with lymphohistiocytic infiltration of edematous septae and periphery of fat lobules. Necrosis of vessel walls or fat lobules was not observed. The patient responded to therapy with potassium iodide and naproxen.
