Body was changed:

Granulomas are organised conglomerates of histiocytes, a specialised white blood cell 1. They form by the process of granulomatous inflammation, which is a specific type of chronic inflammation that occurs following cellular injury as a response to the mediators that are released. A broad range of insults, including infections, autoimmune, foreign bodies, allergens and neoplastic disease, may trigger the formation of granulomas. This inflammatory response is seen at all ages and in all body tissues.

Terminology

It is important to not confuse granuloma with granulation tissue, the latter describes the new tissue that forms as part of the healing of an injury. 

Two lesions of the oral cavity that are commonly called granuloma are misnomers. These are a pyogenic granuloma, which is an angiomatous lesion rather than a true granuloma 3, and a periapical granuloma which consists of chronic granulation tissue 4.
