Term Definition
Granuloma

Special form of chronic inflammation; often forms one or more nodules that can involve the skin, lymph nodes, lung, liver, spleen, or other organs. Granulomas often form in response to certain types of infection (especially to mycobacteria such as in tuberculosis and to fungi) or to foreign bodies, but sometimes have no known cause, as in sarcoidosis.
