because they have esophageal, gastric, or neurologic problems. Intake of drugs that depress neurologic function may also lead to aspiration. The resultant granulomas are typically found around the airways (bronchioles), and are often accompanied by foreign body-type, multinucleated giant cells, acute inflammation, or organizing pneumonia. The finding of food particles in lung biopsies is diagnostic.
436: 415:) refers to a form of necrosis that, to the unaided eye, appears cheese-like ("caseous"), and is typically a feature of the granulomas of tuberculosis. The identification of necrosis in granulomas is important because granulomas with necrosis tend to have infectious causes. Several exceptions to this general rule exist, but it nevertheless remains useful in day-to-day diagnostic pathology. 719:
is typically caused by aspiration of bacteria from the oral cavity into the lungs, and does not result in the formation of granulomas. Granulomas may form, though, when food particles or other particulate substances such as pill fragments are aspirated into the lungs. Patients typically aspirate food

is a disease of unknown cause characterized by non-necrotizing ("non-caseating") granulomas in multiple organs and body sites, most commonly the lungs and lymph nodes within the chest cavity. Other common sites of involvement include the liver, spleen, skin, and eyes. The granulomas of sarcoidosis

which tend to contain necrosis ("caseating tubercules"), but non-necrotizing granulomas may also be present. Multinucleated giant cells with nuclei arranged like a horseshoe (Langhans giant cell) and foreign body giant cells are often present, but are not specific for tuberculosis. A definitive

occurs when a foreign body (such as a wood splinter, piece of metal, glass etc.) penetrates the body's soft tissue followed by acute inflammation and formation of a granuloma. In some cases the foreign body can be found and removed even years after the precipitating event.

is a skin disease of unknown cause in which granulomas are found in the dermis of the skin, but it is not a true granuloma. Typically, a central zone of necrobiotic generation of collagen is seen, with surrounding inflammation and mucin deposition on pathology.
259:. Epithelioid macrophages differ from ordinary macrophages in that they have elongated nuclei that often resemble the sole of a slipper or shoe. They also have larger nuclei than ordinary macrophages, and their cytoplasm is typically pinker when stained with 540:

is an inflammatory condition of uncertain cause characterized by severe inflammation in the wall of the intestines and other parts of the abdomen. Within the inflammation in the gut wall, granulomas are often found and are a clue to the diagnosis.

infection in the lungs is usually not associated with granulomas, but rare cases are well documented to cause granulomatous inflammation. The diagnosis is established by finding Pneumocystis yeasts within the granulomas on lung biopsies.
555:, typically acquired by a scratch from a kitten infected with the organism. The granulomas in this disease are found in the lymph nodes draining the site of the scratch. They are characteristically "suppurative", i.e., 628:, but these structures are not specific for sarcoidosis. Sarcoid granulomas can resolve spontaneously without complications or heal with residual scarring. In the lungs, this scarring can cause a condition known as 333:
In terms of the underlying cause, the difference between granulomas and other types of inflammation is that granulomas form in response to antigens that are resistant to "first-responder" inflammatory cells such as
