Description
Summary:Erythema elevatum diutinum (EED) is a rare cutaneous neutrophilic vasculitis with many associated diseases reported in the literature. We report a 65-year-old woman with painful and itchy lesions on her elbows, hands, knees, and foot for a year. Histopathologic examination confirmed the diagnosis of erythema elevatum diutinum and treatment with dapsone produced significant clinical improvement within few weeks. Erythema elevatum diutinum is a rare disease that should be considered in patients with violaceous nodular plaques located over the extensor regions of the limbs. Knowledge of this unusual pathology and its association helps to avoid misdiagnosis and late treatment.
