Sarcoidosis - Crystalline inclusion with developing Schaumann body, polarized
The crystalline inclusions that may be found within the giant cells in sarcoidosis and other granulomatous disorders consist mainly of calcium oxalate and well as some calcium carbonate. The concentric rings of calcification in association with the crystals represent a Schaumann body. In many cases the crystals appear to serve as a nidus around which Schaumann bodies are formed. H&E stain.
