Heterotopic gastrointestinal cysts (HGCs) of the oral cavity are rare benign lesions mimicking benign or malignant pathologies. These cysts are usually discovered during infancy but may not appear until well into adulthood. The epithelial lining of these cysts shows variable presentation with the presence of an enteric lining as an essential component. The histogenesis is related to entrapment ...

BACKGROUND Intestinal intussusception is the most frequent cause of small bowel obstruction in children between the ages of 2 months and 5 years and often remains idiopathic in etiology, even after surgery. On microscopic examination, in intussusception normal mucosa is noted but in a few cases heterotopic tissue can be seen. Heterotopic gastric mucosa in the small intestine is extremely rare e...

Barrett’s esophagus is a premalignant condition that arises due to chronic acid reflux in which the normal squamous epithelium of the esophagus is replaced by a metaplastic columnar epithelium. A fundamental question is the distinction between neoplastic Barrett’s epithelium and surrounding normal tissues of the upper gastrointestinal tract. For example, although it arises in the esophagus, the...

The development of pancreatic tissue outside the confines of the main gland, without anatomic or vascular connections between them, is a congenital abnormality referred to as heterotopic pancreas. A heterotopic pancreas in the gastrointestinal tract is usually discovered incidentally and the risk of its malignant transformation is extremely low. In this study, we describe the first case of endo...

UNLABELLED Meckels diverticulum is the most frequent congenital malformation of the gastrointestinal tract. The most common ectopic tissue within a Meckels is heterotopic gastric mucosa, with bleeding being the most common presentation. However, perforation of a Meckels diverticulum is a rare presentation. NSAID-associated Meckels perforation has been suggested, however has not been documented ...

Short bronchial segments obtained by pneumonectomy were implanted, 9-12 per dog, in the subcutaneous tissues of the back of seven dogs. These subcutaneous bronchial autografts (SBA) became vascularized, and they contained viable, histologically normal respiratory epithelium 4 wk after implantation. From 1-3 mo after implantation, 10% methylcholanthrene in steroid suspension medium was instilled...

Heterotopic gastric mucosa is rare in the paediatric population, but it can pose a diagnostic challenge. This pathology occur any part of digestive tract, from oropharynx to anorectal area. Most cases are observed esophagus, duodenum and hepatobiliary system, presence this tissue rectum extremely rare. Purpose - conduct clinical description children order pay doctors` attention need for compreh...

Oral heterotopic gastrointestinal cyst is rarely seen in the oral cavity. The tongue and floor of the mouth are the most commonly affected sites. These cysts may cause feeding and respiration problems, especially in newborns and infants. A benign mass was considered according to the physical examination and ultrasonography findings. We treated the patient with simple excision. We present a thre...
