Meaning and Definition
A small area of inflammation in body tissue, typically consisting of a collection of immune cells, often caused by infection, foreign material, or autoimmune disease.
In pathology and medicine, a granuloma is a structured aggregate of macrophages and other immune cells that forms as the body's response to persistent, poorly degradable antigens or irritants. While most commonly referring to a medical condition, the term can be used metaphorically in academic discourse to describe a persistent, localized problem.
