ERITEMA ELEVATUM ET DIUTINUM AND THE TRIGGER FACTOR’S ROLE IN ITS PATHOGENESIS – CASE REPORT -
Abstract:
Eritema elevatum et diutinum (EED) is a rare form of leukocytoclastic vasculitis, with unknown etiology, whose onset could involve infections, autoimmune diseases or monoclonal gammopathy. We present the case of a female patient, who came with the recent onset of a rash that consisted of erytematous papules and nodules localized on the interphalangian joints and thenar eminence, associated with local burn, pain and arthralgia in the small joints of the hands. Clinically, the lesions had a particular aspect, with inflammatory characteristics and abcedation tendency, which oriented the diagnosis towards EED. There were some differential diagnosis problems with other vasculitis. The histophatological exam confirmed the diagnosis of EED. In our case, there were multiple trigger factors such as bacterial and fungal infections, hepatitis with C virus and tuberculinic hiperergy.
