We report a case of a 65-year-old marathon runner who presented with painful plaques, which were worse in cold weather and progressed to ulceration. A punch biopsy revealed vascular endothelial hyperplasia and an appearance consistent with reactive angioendotheliomatosis (RAE), a rare, but benign disorder of the skin. Subsequent investigations resulted in the diagnosis of type I cryoglobulinemia; the lesions resolved completely following treatment of the underlying disorder with lenalidomide.
