Introduction: Heterotopic gastrointestinal cyst of the oral cavity is an extremely rare lesion with fewer than 40 cases reported in the English literature. It usually involves the soft tissue covering the floor of the mouth and the tongue. Lining of this lesion resembles gastric or intestinal mucosa. Case Report: In this report we describe the lesion in two boys and discuss their pathogenesis.

  Aneurysms of gastric vessels (Dieulafoy`s disease, caliber-persistent artery) are thought to be of malformative rather than degenerative origin. They are usually single, located in the submucosa, usually on the lesser curvature, and characterized by a large tortuous vessel surmounted by a small defect...

The gastrointestinal mucosa forms a barrier between the body and a lumenal environment which not only contains nutrients, but is laden with potentially hostile microorganisms and toxins. The challenge is to allow efficient transport of nutrients across the epithelium while rigorously excluding passage of harmful molecules and organisms into the animal. The exclusionary properties of the gastric...

Pigmented spots in the skin and mucosa (lentigines) can be found in various diseases called familial lentiginosis syndromes; Peutz-Jeghers syndrome (PJS) is one of them. It is characterized by the association of mucocutaneous melanin pigmentation and hamartomatous gastrointestinal polyps. Patients with PJS are at increased risk of intussusception and cancer development (gastrointestinal and non...

Tactile corpuscle-like bodies (TCLBs) are specialized mechanoreceptors found in the dermal papilla of glabrous skin. They normally not gastrointestinal (GI) mucosa. There has been an increase incidental detection GI mucosa due to widespread use colonoscopy procedures. However, TCLB's clinical implications tract remain unknown. We present a case 74-year-old man who was noted have TCLBs rectosigm...

 Aim: The current study aimed to investigate anatomy and histology intestine in (Columba palumbus). 
 Materials methods: Animals were collected Al-N...

The gastrointestinal immune system is involved in the development of several autoimmune-mediated diseases, including inflammatory bowel disease, multiple sclerosis, and type 1 diabetes mellitus. Alterations in T-cell populations, especially regulatory T cells (Tregs), are often evident in patients suffering from these diseases. To be able to detect changes in T-cell populations in diseased tiss...

Childhood gastrointestinal dysfunction has been recognized as the triggering elements of multiple organ failure. The causes of gastrointestinal dysfunction include: injury of intestinal barrier, release of inflammatory mediators, translocation of intestinal bacteria, gastrointestinal mucosal ischemia and anoxia injury caused by abnormal intestinal blood flow perfusion, and apoptosis of gastroin...
