A woman in her 50s presented with a 20 day history of painful erythematous nodules on the legs and intermittent ankle arthralgia. Physical examination showed multiple, firm, tender, erythematous nodules on the lateral aspect of both legs (fig 1). Computed tomography imaging of the chest showed right hilar and mediastinal lymphadenopathy. Histopathological examination of the leg nodules and enlarged lymph nodes showed septal panniculitis and non-caseating granulomas respectively, indicating erythema nodosum and sarcoidosis. She was diagnosed as having Lofgren’s syndrome.
