Erythema Elevatum Diutinum Mimicking Extensive Keloids

We report an unusual case of erythema elevatum diutinum (EED) that mimicked extensive keloids. A 53-year-old man presented with a 6-year history of painful, enlarging nodules over the legs, feet, arms, hands, and back. Although the clinical morphology of the lesions resembled extensive keloids, histopathologic examination confirmed a diagnosis of EED. After initiating therapy with dapsone, the patient quickly experienced dramatic improvement in the appearance of the lesions. This article details the unusual characteristics of our case and reviews the important considerations involved in the diagnosis and treatment of EED.
