granuloma
- Noun:
- A tumor composed of granulation tissue: A granuloma is a small area of inflammation, forming a mass or nodule. It is made up of granulation tissue, which is new connective tissue and tiny blood vessels that form on the surfaces of a wound during healing. This structure typically results from the body's attempt to wall off substances it perceives as foreign but cannot eliminate, such as from certain infections, chronic inflammation, or injury.
