[Erythema elevatum et diutinum].

Erythema elevatum et diutinum (EED) is a rare, chronic, cutaneous, leukocytoclastic vasculitis. It is characterized by symmetric, plaques, papules and nodules occurring preferentially on the extensor aspects of the arms. An association with chronic infections, neoplasms, especially myeloproliferative diseases and paraproteinemia, as well as autoimmune disorders (rheumatoid arthritis, Crohn disease) has been described. An 83-year-old woman with EED presented with symmetric, skin colored, firm nodules on the extensor surfaces of her fingers for two years. This case report summarizes the central clinical aspects and differential diagnosis of EED as well as its therapeutic options.
