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
Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens.

Klebsiella granulomatis is a Gram-negative, rod-shaped bacterium of the genus Klebsiella [1] known to cause the sexually transmitted infection granuloma inguinale (or donovanosis). It was formerly called Calymmatobacterium granulomatis. [2] It is a non-motile aerobic bacillus with a non-sporulated capsule measuring 0.5 to 2.0 μm.
B: T1-weighted MRI showing expansion of the brain infection 4 days later. Granulomatous amoebic encephalitis (GAE) [2] is a rare, often fatal, subacute-to-chronic central nervous system disease caused by certain species of free-living amoebae [3] of the genera Acanthamoeba, Balamuthia and Sappinia. [4] [5] The term is most commonly used with ...
[11] [12] The proper clinical designation for donovanosis is "granuloma inguinale". [5] A granuloma is a nodular type of inflammatory reaction, and inguinale refers to the inguinal region, which is commonly involved in this infection. The disease is commonly known as donovanosis, after the Donovan bodies seen on microscopy, which are a ...
Histologically, sarcoidosis of the heart is an active granulomatous inflammation surrounded by reactive oedema. The distribution of affected areas is patchy with localised enlargement of heart muscles. This causes scarring and remodelling of the heart, which leads to dilatation of heart cavities and thinning of heart muscles.
Eating meat that has not been cooked sufficiently to kill E. coli can cause infection, according to Mitzi D. Baum, CEO of Stop Foodborne Illness in Chicago. ... Infections can be caused by ...
On histopathological examination, a biopsy will show leukocytoclastic vasculitis with necrotic changes and granulomatous inflammation (clumps of typically arranged white blood cells) on microscopy. These granulomas are the main reason for the name granulomatosis with polyangiitis, although it is not an essential feature.
