Granuloma; Picture of a granuloma (without necrosis) as seen through a microscope on a glass slide: The tissue on the slide is stained with two standard dyes (hematoxylin: blue, eosin: pink) to make it visible. The granuloma in this picture was found in a lymph node of a patient with a Mycobacterium avium infection. Specialty: Pathology
Sarcoidosis is characterized by the formation of non-necrotizing ("non-caseating") granulomas in various organs and tissues. [95] Giant cells, specifically Langhans giant cells, are often seen in sarcoidosis. [96] Schaumann bodies seen in sarcoidosis are calcium and protein inclusions inside of giant cells as part of a granuloma. [97]
Caseous necrosis in the kidney. In caseous necrosis no histological architecture is preserved (unlike with coagulative necrosis). [5] [6] On microscopic examination with H&E staining, the area is acellular, characterised by amorphous, roughly granular eosinophilic debris of now dead cells, [6] also containing interspearsed haematoxyphilic remnants of cell nucleus contents. [5]
Accumulation of granulomas in particular areas of the brain can lead to abnormalities in the function of that area. For instance, involvement of the internal capsule would lead to weakness in one or two limbs on one side of the body. If the granulomas are large, they can exert a mass effect and cause headache and
They may appear as either non-caseating or solidly caseating lesions. [20] Initially, tuberculomas appear hypodense on computed tomography (CT) scans with significant surrounding edema. [ 23 ] [ 3 ] The "target sign" is pathognomonic for tuberculoma on CT, with a nodular ring-enhancing mass and central calcification.

It usually includes the formation of a foreign body granuloma. [2] Tissue encapsulation of an implant is an example, as is inflammation around a splinter . [ 3 ] Foreign body granuloma formation consists of protein adsorption , macrophages , multinucleated foreign body giant cells (macrophage fusion), fibroblasts , and angiogenesis .
And I'm an adult. I have children that are counting on me. I mean, they don't listen to me, but I can't just curl up in a ball and mope. Sometimes I'm embarrassed how detached I feel about it.
