Reactive gastropathy, is characterized histologically by: [2] - Foveolar hyperplasia (black arrow), as a tortuosity in the "neck" region of the gastric glands. - Scant or minimal inflammatory cells (white arrow), i.e. lack of large numbers of neutrophils and plasma cells.. - Smooth muscle hyperplasia in the lamina propria (in black oval).
The area between the stratified and the intestinalized epithelium displays reactive changes, but there is no secondary dysplasia in this case. H&E stain. Barrett's esophagus occurs due to chronic inflammation. The principal cause of chronic inflammation is gastroesophageal reflux disease, GERD (UK: GORD). In this disease, acidic stomach, bile ...
Micrograph of Barrett's esophagus (left of image) and normal stratified squamous epithelium (right of image). Alcian blue stain.. Glandular metaplasia is a type of metaplasia where irritated tissue converts to a glandular form.
Common sites for squamous metaplasia include the bladder and cervix. Smokers often exhibit squamous metaplasia in the linings of their airways. These changes don't signify a specific disease, but rather usually represent the body's response to stress or irritation.
Reactive stains undergo an observable change due to a chemical process related to the function of the gastrointestinal tract. Congo red is used as a test for achlorhydria in the stomach, to test adequacy of vagotomy ( post adequate vagotomy, gastric acid secretion is abolished) and to detect presence of ectopic gastric tissue, as it changes ...
Most people with Peutz–Jeghers syndrome will have developed some form of neoplastic disease by age 60. Most patients will develop flat, brownish spots ( melanotic macules ) on the skin, especially on the lips and oral mucosa, during the first year of life, and a patient's first bowel obstruction due to intussusception usually occurs between ...
Having more fat around your midsection may make you more likely to develop Alzheimer’s disease.. A specific type of body fat — visceral fat — around the midsection has been linked to the ...
Hereditary mucoepithelial dysplasia (HMD), or simply mucoepithelial dysplasia, [1] [2] is a rare autosomal dominant multiepithelial disorder causing systemic maldevelopment of the epithelia and mucous membranes that line the surface of tissues and structures throughout the body, particularly affecting systems affiliated with mucosa, which includes the respiratory, digestive, urinary ...
