Foreign body granuloma from a gunshot injury to the breast

Granulomatous disease may be due to multiple etiologies, including infections, inflammation, and foreign substances. A granuloma results from the accumulation of immune cells around this agent that the body recognizes as unnatural. While often nonspecific, unique clues may be ascertained with appropriate history and correlation across modalities that allow for a specific diagnosis without the need for an unnecessary biopsy.
