Cartilaginous metaplasia is a rare but well-documented phenomenon occurring in the wall of odontogenic keratocyst. The mural cartilage not associated with odontogenic keratocyst has been reported only once in a maxillary teratoid cyst of congenital origin to our knowledge. A case presented is a 38-year-old man with intraosseous keratinizing epidermoid cyst in the mandible, the wall of which con...

Gastric duplication cysts comprise 2-7% of gastrointestinal duplications, rare congenital malformations that can be present at almost any part of the alimentary tract. They mostly present with gastrointestinal obstruction symptoms, ulceration, and painless hemorrhage. Symptoms include nausea, vomiting, and fullness sensation. Gastric duplications are mostly cystic in shape. Herein, we present a...

Osseous metaplasia is a phenomenon which is described in a variety of tissue types with respect to both neoplastic and non-neoplastic conditions. In the gastrointestinal tract, osseous metaplasia (heterotopic bone formation) is rarely detected. Most of the reported cases were associated with malignant lesions. Here, we are reporting a rare case of a juvenile rectal polyp in a 14 years male, whi...

While ovarian masses are common findings in gynecology, unusually huge masses are quite rare. However, such cases can still be found today. Mismanagement of common complaints in patients can be a leading cause of facing such findings. Herein, we introduce a case of a giant ovarian cyst, which was mismanaged in a young virgin female patient. The patient had received gastrointestinal medications ...

Gastrointestinal duplication is a rare congenital disease which affected more commonly the ileum, while the stomach is rarely involved. Generally diagnosed in paediatric or young age, it could be difficult to suspect a gastrointestinal duplication in adults. Herein, we report a 55-year-old male with a gastric duplication cyst found on routinely checkup for chronic hepatitis and first misdiagnos...

RATIONALE Heterotopic gastric mucosa has been described at various locations of the body; however, the polyp composed of heterotopic gastric mucosa in the small intestine is rare. PATIENT CONCERNS A 15-year-old boy visited us for investigation of recurrent episodes of melena. Capsule endoscopy (CE) revealed a polypoid tumor in the ileum, with an active nearby hemorrhage. Contrast-enhanced com...

Abstract Background The oral lymphoepithelial cyst (LEC) is a rare, soft-tissue, developmental cyst, initially presented by Gold in 1962 as “branchial cleft cyst”. It may occur the pancreas, tongue, neck, and other regions of cavity. No study has been reported Pakistan Karachi reporting case submandibular region. This rare LEC to help clinicians bring into their differential diagnosis for lesio...

Objectives. Duplication cysts are rare benign lesions usually arising in the gastrointestinal tract. We report a case of a 52-year-old woman with an incidental gastric mass found on computed tomography during a pregraft workup for a familial cardiomyopathy. Methods. The mass was completely excised by partial gastrectomy and gross examination revealed a cystic lesion containing two small solid n...

The finding of ectopic gastric mucosa is well documented throughout the gastrointestinal tract from the tongue to the rectum. Its presence within the gallbladder and the biliary tree is extremely rare and most probably secondary to an aberrant histogenesis. This brief report presents the second reported case of heterotopic gastric tissue within the common bile duct. A literature review, brief o...

A heterotopic pancreas in the gastrointestinal tract is mostly found incidentally and its malignant transformation is extremely rare. We describe the second case of adenocarcinoma arising in a gastric heterotopic pancreas of an asymptomatic 35-yr-old man in Korea. Esophagogastroduodenoscopy revealed a submucosal tumor with an irregular central umbilication in the gastric antrum. A wedge resecti...
