Sarcoidosis is non-necrotizing granulomatous disease of unknown etiology. It classically associated with (pulmonary) hilar lymphadenopathy. It may be found in almost any organ, e.g. heart, appendix.
General
- Diagnosis of exclusion - infection must be excluded.
- Rare.
Gross
- Bilateral lymphadenopathy ~90% of cases.
Note:
- Radiologic differential diagnosis includes carcinomatosis.[1]
Microscopic
Features:
- Granulomata, well-formed, non-necrotizing.
- Usu. minimal (lymphoid) inflammation; sarcoid granulomas are known as "naked granulomas".[2]
- In lung: interstitial location.
