Sarcoidosis-
http://www.meddean.luc.edu/lumen/bbs/p/pulpath5.html

The histologic hallmark is lymphangitic distribution of non-caseating granulomas with Langhan's or foreign body type giant cells.

Within the granulomas there may be calcified, rounded, laminated concretions known as Schumann's bodies.

With the giant cells there are often star-shaped inclusions (Asteroid bodies).

The above two are characteristic but not diagnostic of sarcoidosis.

There is varying degree of fibrosis around granulomas and in the interstitium.

Sarcoidosis is a diagnosis of exclusion.
