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...

abstractintroduction: hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. they are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. these protrusions are mucosal regenerative response to surrounding mucosal injury. case: here we present a 9-year-old boy presenting with abdomi...

Endoscopic submucosal dissection (ESD) is an effective, safe technique for treating gastric lesions [1]. Hyperplastic polyps have an underestimated risk formalignancy, which has been reported to be 3.7% in 809 lesionsmeasuringmore than 1cm [2]. Thus, complete en bloc resectionwith ESD is an option to avoid local recurrence [3], particularly when hyperplasia is associatedwith dysplasia. We repor...

Gastritis cystic polyposa/profunda (GCP) is defined as a hyperplastic polyp that contains foci of misplaced foveolar and/or glandular epithelium in the muscularis mucosae or in the deeper portions of the submucosa or the muscularis propria [1-6]. The lesion called polyposa when an intraluminal polyp is present [1,2] and profunda when the cystic lesion located within the submucosa [3] and the bu...

Gastritis cystica profunda (GCP) is an uncommon hyperplastic benign lesion, and histologically characterized by hyperplasia and cystic dilatation of the gastric glands extending into the submucosal layer. GCP usually occurs at a gastroenterostomy site, although it can occasionally be found in an unoperated stomach. GCP is thought to be a possible precancerous lesion, since a few early gastric c...

A 34-year-old man with hypercalcemia had a sestamibi scan that showed increased uptake that appeared to correspond with a 7 mm density in the mediastinum, adjacent to the aortic arch, on chest CT. This lesion was thought to be consistent with an ectopic parathyroid adenoma. Prior to surgical exploration, the patient was injected intravenously with 12.3 millicuries of Tc99m-sestamibi. The lesion...

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 ...
