Granuloma

definition

An imprecise term applied to (1) any small nodular delimited aggregation of mononuclear inflammatory cells, or (2) such a collection of modified macrophages resembling epithelial cells, usually surrounded by a rim of lymphocytes, often with multinucleated giant cells. Some granulomas contain eosinophils and plasma cells, and fibrosis is commonly seen around the lesion. Granuloma formation represents a chronic inflammatory response initiated by various infectious and noninfectious agents. (Dorland, 27th ed)
