Sarcoidosis is a disease of unknown cause characterized by non-necrotizing ("non-caseating") granulomas in multiple organs and body sites, [12] most commonly the lungs and lymph nodes within the chest cavity. Other common sites of involvement include the liver, spleen, skin, and eyes.
Sarcoidosis is characterized by the formation of non-necrotizing ("non-caseating") granulomas in various organs and tissues. [95] Giant cells, specifically Langhans giant cells, are often seen in sarcoidosis. [96] Schaumann bodies seen in sarcoidosis are calcium and protein inclusions inside of giant cells as part of a granuloma. [97]
One of the most reliable distinguishing factors from plasmacytomas and plasma cell granulomas, is the polyclonality of the plasma cells involved with plasma cell granulomas. [3] PCGs that manifest in the mouth, specifically the gingiva, have been seen to exhibit similar physical characteristics of other conditions such as epulis, fibroma ...
Sarcoidosis is an additional cause of a mosaic GGOs due to the formation of granulomas in interstitial areas. This may coexist with granulomatosis with polyangiitis, leading to diffuse areas of increased attenuation with ground-glass appearance.
Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens.

Chronic exposure to beryllium can be histologically characterised by non-caseating granulomas—structures formed in certain infectious and toxin-mediated diseases in which tissue resident macrophages build a wall around the threat, thus nullifying it. Because of this, beryllium associated granulomas are occasionally responsive to steroids and ...
Persons with these findings, if they have a positive tuberculin skin test reaction, should be considered high-priority candidates for treatment of latent infection regardless of age. Conversely, calcified nodular lesions (calcified granuloma) pose a very low risk for future progression to active tuberculosis. [citation needed]
A foreign body reaction (FBR) is a typical tissue response to a foreign body within biological tissue. [1] It usually includes the formation of a foreign body granuloma. [2] ...
