A 63-year-old diabetic woman presented with new-onset intermittent claudication of the right calf accompanied by ipsilateral necrobiosis lipoidica (NL). The latter presented the typical appearance of oval, indurated plaques, with brownish-red margins and central atrophy, scattered over the right thigh and calf. Arteriography demonstrated severe obstructive lesions on the right femoral artery. NL and claudication spared the left leg. A possible ischemic pathogenesis of NL emerges from this observation and is supported by recent studies in the literature.
