Sarcoidosis

Background

  • Abnormal collection of inflammatory cells (granulomas) throughout the body.
    • Most common location for granulomas to occur are the lung, skin, heart, and brain.
    • Exact cause unknown - thought to be related to an immune reaction to a prior insult such as infection or chemical exposure earlier in life.
    • Do not confuse with infectious granulomatous processes such as tuberculosis.

Clinical Features

Depend on location of granulomata. May be entirely asymptomatic.

Differential Diagnosis

Evaluation

  • Definitive initial diagnosis unlikely to be made in ED, but may be suggested by typical granulomatous lesions seen on CT or other imaging in setting of appropriate clinical context
  • Evaluate for complications/alternative diagnoses of presenting symptoms

Management

Disposition

  • Dependent on presentation
