The definition of the condition includes the requirement that the duodenal histological appearances are otherwise unremarkable, specifically with normal villous architecture. [2] In coeliac disease (also known as gluten-sensitive enteropathy), duodenal lymphocytosis is found in untreated or partially treated cases. This is the least severe type ...
Biopsy of small bowel showing coeliac disease manifested by blunting of villi, crypt hyperplasia, and lymphocyte infiltration of crypts. OGD to detect duodenal pathology and obtain D2 biopsy (for coeliac disease, tropical sprue, Whipple's disease, abetalipoproteinaemia etc.) Enteroscopy for enteropathy and jejunal aspirate and culture for ...
Both anti-transglutaminase and anti-endomysial antibodies have high sensitivity to diagnose people with classic symptoms and complete villous atrophy, but they are only found in 30–89% of the cases with partial villous atrophy and in less than 50% of the people who have minor mucosal lesions (duodenal lymphocytosis) with normal villi.

A 'Whipple' procedure is a type of surgery that is sometimes possible with this cancer. In this procedure, the duodenum, a portion of the Pancreas (the head), and the gall bladder are usually removed, the small intestine is brought up to the Pylorus (the valve at the bottom of the stomach) and the liver and pancreatic digestive enzymes and bile ...
Epithelium of small intestine contains approximately 1 IEL per 10 enterocytes. [3] Due to their constant exposure to of antigens at mucosal barrier, they have unique antigen-experienced activated phenotypes and they constantly express CD103 (αE integrin), that is distinct from the conventional T cells in the intestine. [3]
Duodenal-type follicular lymphoma (DFL) is a form of lymphoma in which certain lymphocyte types, the B-cell-derived centrocytes and centroblasts, form lymph node follicle-like structures principally in the duodenum and other parts of the small intestine. It is an indolent disease which on rare occasions progresses to a more aggressive lymphoma ...
Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine.Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border.
Biopsy of the small intestine shows dilation of the lacteals of the villi and distension of the lymphatic vessels. [6] Reduced lymph flow leads to a malabsorption syndrome of the small intestine, especially of fat and fat-soluble vitamins. Rupture of the lymphatics causes protein loss into the intestines. [7]
