“…For SMT-type lesions larger than 10 mm in diameter, surgical resection is performed 5. Furthermore, approximately 20 % of GHIPs coexist with precancerous or cancerous areas 6 7 8. In our patient, the diameter of the SMT was about 15 mm, so we selected ESD rather than conventional EMR to achieve a complete en bloc resection and obtain an accurate pathological diagnosis.…”

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 originating from the second layer. The patient was clinically asymptomatic, with no contributory family history or abnormal laboratory data. The results of a physical examination, abdominal computed tomography, and plain chest radiography were all unremarkable. Although the endoscopic tumor type was determined to be SMT, the tumor was successfully resected by endoscopic submucosal dissection (ESD) and subsequently diagnosed as a gastric hamartomatous inverted polyp (GHIP). The findings of the present case highlight the importance of considering GHIP as a diagnosis and indicate the utility of en bloc resection of GHIP with ESD.

“…According to a search of the PubMed database, only four reports have described GHIP removal by ESD 4 7 8 9. The resection of an SMT-type GHIP by ESD is thus quite rare.…”

“…It has also been called as hamartomatous polyp 1 and solitary polypoidhamartoma. 2 To our knowledge, there are only 12 reports in the English literature, [1][2][3][4][5][6][7][8][9][10][11][12] and only 1 report of gastric IHP composed of pure pyloric-type glands. 4 Gastric IHP is usually treated by endoscopic submucosal dissection.…”

“…It has clinical importance, because it can be misdiagnosed as submucosal tumor or malignant neoplasm, and adenocarcinoma can likely form in benign gastric IHP. 8,9,11,12 Therefore, it is difficult and challenging for preoperative diagnosis. In this report, we describe endoscopic, gross, histological findings, and immunohistochemical expression of a rare gastric IHP, only composed of pyloric glands.…”

Gastric Inverted Hyperplasic Polyp Composed Only of Pyloric Glands

Inverted hyperplastic polyp (IHP) in stomach is a rare benign gastric polypoid lesion, characterized by downward growth of hyperplastic mucosal glands into the submucosal layer. In most previous reported cases, gastric IHP showed mixtures of fundic-type gland, pyloric-type gland, and foveolar-type epithelium. Also, a case of IHP composed of only one type of gland is extremely rare. This report describes a case of a 70-year-old man with gastric IHP, composed only of pyloric-type gland. It was removed completely by endoscopic submucosal dissection, and patient showed no recurrence over 2 years after treatment.
