Erythema Elevatum Diutinum Associated with Tuberculosis

Abstract

Erythema elevatum diutinum (EED) is a rare small vessel vasculitis with cutaneous manifestations most commonly presenting as red or brown papules, plaques, and nodules on extensor surfaces. It is a chronic, relapsing disease that is often associated with states of immunocompromise, e.g., HIV, gammaglobulinemias, and, more rarely, tuberculosis. Currently oral dapsone is the current treatment of choice, and while most patients respond well, it is imperative that the diagnosis be made early. We report a rare case of EED associated with underlying tuberculosis infection. Recognizing the distinct manifestations of EED and understanding its immunologic and infectious disease associations may enable clinicians to properly recognize, manage, and treat patients with EED.
