polyp in the intrahepatic biliary duct Hamartomatous polyps are usually found as part of Peutz–Jeghers Syndrome (PJS) and are uncommon, but occasionally a solitary hamartomatous polyp may develop in an otherwise healthy patient [1]. Hamartomatous polyps may appear commonly in the stomach, small bowel, or colon, with hamartomatous features on histology [2,3]. Polyps at extraintestinal sites such...

Juvenile polyposis syndrome (JPS) is an autosomal dominant predisposition to the occurrence of hamartomatous polyps in the gastrointestinal tract. Diagnosis of JPS is based on the occurrence of numerous colon and rectum polyps or any number of polyps with family history and, in the case of juvenile polyps, their occurrence also outside the large intestine. The JPS is caused by mutations in SMAD...

We report a case of gastric hamartomatous inverted polyps that are a rare histological type of gastric polyp and difficult to diagnose. Gastric submucosal tumor was detected by upper gastrointestinal X-ray series in 37-year-old man. Endoscopy revealed a submucosal tumor (SMT) , which eroded with a depression on its surface in the fornix. Endoscopic ultrasonography showed a heterogeneous tumor i...

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with mucocutaneous pigmentations. Here we present a case of a 30-year-old woman who was hospitalized and underwent diagnostic procedures because of crampy abdominal pain. Physical examination on admission revealed pigmented spots around lips and on the oral mucosa. ...

Peutz-Jeghers syndrome was diagnosed in a 51-year-old woman presenting with iron deficiency anaemia. Upper gastrointestinal endoscopy and colonoscopy revealed several hamartomatous polyps in the stomach, duodenum and colon, which were removed. At a combined surgical-endoscopic procedure, 42 hamartomatous polyps were removed from the small intestine by snare polypectomy. This enteroscopic proced...

RATIONALE Peutz-Jeghers syndrome (PJS) is an autosomal dominant genetic syndrome characterized by a unique type of gastrointestinal hamartomatous polyp associated with oral and anal mucocutaneous pigmentations. Peutz-Jeghers polyps occur most numerously in the small intestine but frequently in the colon and stomach, only a few cases have been reported in the duodenum. PATIENT CONCERN A furthe...

Cronkhite-Canada syndrome is a rare, hamartomatous polyposis syndrome of unknown etiology. Hamartomatous gastro-intestinal polyps, alopecia, onychodystrophy, cutaneous hyperpigmentation, abdominal pain, diarrhea, and complications of weight loss are typical of the syndrome. In this report, we describe a pathological finding of colonic adenomatous polyposis as opposed to hamartomatous polyposis....
