Lfgren`s Syndrome: An Acute Variant of Sarcoidosis Diagnosed by Mediastinoscopy.
J Coll Physicians Surg Pak Jan ;25(2):146-8.

Loffgren's syndrome is an acute clinical form of sarcoidosis that is first described by Sven Loffgren 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 Loffgren's syndrome via mediastinoscopy.
