Erythema Elevatum Diutinum - Two Case Reports, Two Different Clinical Presentations, and a Short Literature Review

BACKGROUND: Erythema elevatum diutinum (EED) belongs to the spectrum of cutaneous leukocytoclastic vasculitides. EED is a very rare dermatosis presenting with reddish to browning papules and plaques. EED may be associated with infections, hematologic and autoimmune disorders. CASE REPORTS: We present two patients with EED, a 50-year-old woman and a 42-year-old man. While the woman shows an association with colitis ulcerosa, the man had an anti-thrombin deficiency. Treatment was started with oral corticosteroid and dapsone, respectively. In both cases, there was a partial and temporary response. CONCLUSIONS: EED is a rare vasculitis with an unusual clinical presentation and a chronic course. Response to treatment is unsatisfactory and in the long-term run sometimes frustrating.
