Granuloma: A granuloma is one of a number of forms of localized nodular inflammation found in tissues. The fact that a granuloma is localized is important. So is its nodularity. Granulomas have a typical pattern when examined under a microscope.

Granulomas can be caused by a variety of biologic, chemical and physical irritants of tissue.

A calcified granuloma is a granuloma containing calcium deposits. Since it usually takes some time for calcium to be deposited in a granuloma, it is generally assumed that a calcified granuloma is an old granuloma. For example, a calcified granuloma in the lung may be due to tuberculosis contracted years earlier that is now dormant.
