Foreign body granuloma
Classification and external resources
ICD-10 L92.3 (ILDS L92.300)
A foreign-body response to talc (talcosis) due to intravenous drug use. H&E stain.

The foreign body granuloma is a response of biological tissue to any foreign material in the tissue.[1] Tissue-encapsulation of an implant is part of this. An infection around a splinter is part of this, too.[2]

The presence of the implant changes the healing response, and this is called the foreign-body reaction (FBR). FBR consists of: protein adsorption, macrophages, multinucleated foreign body giant cells (macrophage fusion), fibroblasts, and angiogenesis.

It can be caused by beryllium.[3]
