Lofgren's syndrome: an acute variant of sarcoidosis diagnosed by mediastinoscopy

Lofgren's syndrome is an acute clinical form of sarcoidosis that is first described by Sven Lofgren as bilateral hilar lymphadenopathy together with Erythema Nodosum [EN] and accompanying arthritis/arthralgia. This syndrome has some differences in terms of treatment, prognosis and recurrence compared to sarcoidosis. In this report, we describe a 70 years old lady who admitted with multiple erythematous lesions and arthralgia of both lower extremities and she was diagnosed as Lofgren's syndrome via mediastinoscopy
