Three cases of gastric hamartomatous inverted polyp diagnosed by endoscopy

Gastric hamartomatous inverted polyp mimicking ectopic pancreas on endoscopy and endosonography.

Gastric hamartomatous inverted polyp (HIP) is difficult to diagnose preoperatively because of its rarity [1,2]. It is pathologically benign, but has been reported as a paracancerous lesion [3–5], and therefore its diagnosis and treatment are clinically important. We report a case of gastric HIP and focus on its special characteristics on endoscopy and endosonography. An 18-mm submucosal tumor w...

A case of gastric hamartomatous inverted polyp resected endoscopically

We report the case of a 55-year-old woman with a tumor in the greater curvature of the upper gastric body. The tumor was incidentally found on an upper gastrointestinal X-ray series performed during a routine medical examination. Whereas endoscopy revealed a gastric submucosal tumor (SMT), endoscopic ultrasonography demonstrated a heterogeneous tumor with small, cystic, hypoechoic spots origina...

Hamartomatous inverted polyp successfully treated by endoscopic submucosal dissection.

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...

A case of early gastric cancer accompanied by a hamartomatous inverted polyp and successfully managed with endoscopic submucosal dissection.

during a regular health check−up in a 59− year−old man. Following barium meal study the SMT was shown to be growing. He visited our hospital for further exami− nation. The upper gastrointestinal endoscopy re− vealed an SMT in the posterior wall of the upper third area of the stomach, with bridging fold and positive cushion sign (l" Figure 1). A focal discoloration of mu− cosa at the top of the ...
