Sarcoidosis is a multisystemic disease of unknown etiology characterized by the presence of non-caseating granulomas in various organs, especially in lungs and mediastinum-hilar lymph nodes. The course of the disease ranges from a self-limited form that affects up to two thirds of patients, to a chronic form that requires prolonged treatment in the remaining cases [1,2]. Clinical features such as erythema nodosum, acute arthritis, and bilateral hilar lymphadenopathy are related with a better prognosis.
