Erythema elevatum diutinum is a rare presentation of cutaneous vasculitis. Typical lesions are papules, plaques, and nodules that may coalesce and later turn to yellow-brown color. The extensor surface of the extremities is the most involved area and older lesions may present xanthomatous appearance. Light microscopy of acute lesions shows neutrophilic, perivascular infiltrate with dermal fibrin deposits, endothelial expansion, and leukocytoclasis. We present a case of erythema elevatum diutinum without associated disease.
