It is termed major aphthous ulceration (MaAU) or major recurrent aphthous stomatitis (MaRAS). Major aphthous ulcers (major aphthae) are similar to minor aphthous ulcers, but are more than 10 mm in diameter and the ulceration is deeper.

Dogs can develop carcinomas of epithelial cells and organs, sarcomas of connective tissues and bones, and lymphomas or leukemias of the circulatory system. Selective breeding of dogs has led certain pure-bred breeds to be at high-risk for specific kinds of cancer. [1] Veterinary oncology is the medical study of cancer in animals, and can be ...
Over time, these T cells commonly spread throughout the mucosal lining of a portion of the GI tract [2] (particularly the jejunum and ileum of the small intestine [3]), lead to GI tract nodules and ulcerations, and cause symptoms such as abdominal pain, weight loss, diarrhea, obstruction, bleeding, and/or perforation.

Deep-chested breeds are at a higher risk of bloating. Factors that predispose dogs to this condition are intestinal foreign bodies, intestinal cancer, intussusception, and other intestinal diseases. It has a poor prognosis. [144] Foreign body is an object foreign to the body that becomes lodged in the gastrointestinal tract (or other part of ...
The diagnosis of EATL is based on endoscopic findings of: 1) flattened duodenal folds and small intestinal fissures and ulcers; 2) biopsy findings of small intestinal inflammation, increased IEL, villous atrophy, and crypt hyperplasia; 3) HLA-DG serology typing and/or gene allele analyses showing results compatible with coeliac disease (see ...
Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine, with Crohn's disease and ulcerative colitis (UC) being the principal types. [3] Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas UC primarily affects the colon ...
Lower endoscopy to evaluate the rectum and distal large intestine (sigmoidoscopy) or entire colon and end of the small intestine (colonoscopy) for ulcers and inflammation; Although ulcerative colitis is a disease of unknown causation, inquiry should be made as to unusual factors believed to trigger the disease.
