Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...

Hyperplastic polyps of the stomach are regarded as benign. However, in rare cases they may contain incipient primary carcinomas. To our knowledge, breast carcinoma metastatic to a gastric hyperplastic polyp has not yet been reported. We describe the case of a 69-year-old woman to whom a gastric polyp was endoscopically excised. The patient had previously undergone a right mastectomy for mixed, ...

Gastric oxyntic gland polyp/adenomas, OGA are uncommon polypoid lesions that arise from oxyntic mucosa located in the body and fundus of the stomach. A case of oxyntic gland polyp/adenoma with typical histological and immunohistochemical features is presented and controversy over nomenclature and biological behavior is discussed.

Here we report the first case of carbohydrate antigen (CA) 19-9-producing early gastric adenocarcinoma arising in polyp. A solitary pedunculated polyp lesion of the stomach, measuring 26 × 20 × 20 mm, was noticed in a 76-year-old Japanese woman due to an abdominal disorder, associated with a markedly high serum CA19-9 level (2,172.6 U/ml). After endoscopic mucosal resection was performed, the C...

AbsractGastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gastroenterostomysite, and almost always on the gastric side. It is characterized by elongationof the gastric foveolae along with hyperplasia and cystic dilatation of the gastricglands extending into the submucosal layer. Esophagogastroduodenoscopy in a47-year-old woman without any history of gastric operation ...

A 23-year-old Caucasian male with Neurofibromatosis Type I (NF-I) was found to have a submucosal nodule at the gastroesophageal junction (GEJ) and underwent endoscopic submucosal dissection. Histological examination revealed two different lesions within the nodule. The dominant lesion was inflammatory/hyperplastic (juvenile-like) polyp with obliterative vasculopathy while the smaller lesion was...

The stomach is far less rich in polyps than is the colon. As a result, we know much less about gastric polyps than colonic polyps, and the literature tends to be much more recent and sparser. About 5 to 10% of biopsies of endoscopic gastric polyps are normal mucosa. The reasons for this include the biopsy forceps missing the lesion, an intramural lesion that is not available to endoscopic biops...

Fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. To our knowledge, sonographic and CT findings of a fibrovascular polyp in the stomach have never been reported. Here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. Sonography r...
