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
Meningitis (inflammation of the lining of the brain) occurs in 3–26 percent of cases. Symptoms may include headache and nuchal rigidity (being unable to bend the head forward). It may be acute or chronic. [1] Accumulation of granulomas in particular areas of the brain can lead to abnormalities in the function of that area.
This is why brain tumors are far more common in elderly adults than younger ones and why people with immune system disorders are also most susceptable to developing brain tumors.
Langhans giant cells are named for the pathologist who discovered them, Theodor Langhans. Like many of the other kinds of giant cell formations, epithelioid macrophages fuse together and form a multinucleated giant cell. The nuclei form a circle or semicircle similar to the shape of a horseshoe away from the center of the cell.
It is a form of granuloma. [2] Gummas are most commonly found in the liver (gumma hepatis), but can also be found in brain, heart, skin, bone, testis, and other tissues, leading to a variety of potential problems including neurological disorders or heart valve disease.
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. Researchers from the University of New Mexico Health ...
The presence of neurofibrillary tangles in the brain is one of the key hallmarks of Alzheimer’s disease. These irregular clumps of protein are closely associated with disease progression.
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.
