Recognition and management of sarcoidosis in the emergency department

Sarcoidosis is a chronic granulomatous disease of uncertain etiology. It can affect essentially every organ system in the human body and its manifestations are protean. Sarcoidosis can present in the emergency department (ED) as de novo disease, as preexisting disease with acute exacerbations, or as chronic debilitation. The authors provide a review of the various manifestations of this disease with emphasis on ED presentation and evaluation.
