Sarcoidosis

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.
- Negative for microorganisms with special stains (PAS-D, GMS, AFB).
Usu. minimal (lymphoid) inflammation; sarcoid granulomas are known as "naked granulomas".^[2]
In lung: interstitial location.

DDx:

Reactive changes - may mimic sarcoidosis.
Drug reaction.
- Anti-TNF therapy.^[3]
- Ipilimumab.^[4]
Infections.
- Syphilis.^[5]
Common variable immunodeficiency.^[6]

Sign out

Should be something like sarcoid-like granulomas and clinical correlation required.
