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 ...

Linitis plastica is a gastric cancer of diffuse histotype that presents in the fundic gland area, and is characterized by thickening of the stomach wall and deformation of the stomach, resulting in a leather bottle-like appearance. A 66-year-old female was admitted to Kagawa University Hospital (Kagawa, Japan) with epigastric pain. X-ray examination revealed reduced gastric distension and defor...

A 63-year-old woman was referred to our hospital to undergo endoscopic therapy for a lesion suspected of being early gastric cancer. A biopsy had already been performed. The diagnosis was adenoma with Helicobacter pylori, but cancer could not be ruled out. Esophagogastroduodenoscopic observations revealed a whitish, elevated lesion 20 mm in diameter with 4 large lobules and a central depression...

We present a case of a 56-year-old man with 3 synchronous gastric tumors. The patient presented with melena, and 3 gastric abnormalities were detected on gastroduodenoscopic examination, including a small ulcerative lesion in the gastric antrum, a submucosal mass in the gastric body, and severe erosion in the fundus. Histological examination of biopsy samples yielded respective diagnoses of gas...

We report a case of mixed adenoneuroendocrine carcinoma (MANEC) of stomach with tubular adenoma and well-differentiated neuroendocrine tumor (WD-NET) in the primary tumor in the stomach giving rise to biphenotypic regional nodal metastases. A 35-year-old woman with abdominal pain was found to have a 1.8-cm gastric lesion, diagnosed as WD-NET (intermediate grade) on the biopsy. The resection spe...

Gastritis cystica profunda (GCP) is a rare, benign lesion of the stomach characterized by polypoid hyperplasia and/or ulcerated mucosal lesion and cystic dilatation of the gastric glands extending into the submucosa or muscularis propria of the stomach. Its etiology and pathogenesis are still incompletely understood. The most important factor is assumed to be a history of prior gastric surgery....

Breast cancer metastases to the stomach are very rare. As characteristics of breast cancer metastases to the stomach, metastases of lobular carcinoma, mainly with signet ring cells, are frequently observed, and they are often difficult to distinguish from a primary gastric cancer with signet ring cells. Moreover, because no characteristic symptoms are shown and they involve a submucosal lesion,...

Goal: Diagnosing the corpus-predominant gastritis index (CGI) which is an early precancerous lesion in stomach has been shown its effectiveness identifying high gastric cancer risk patients for preventive healthcare. However, invasive biopsies and time-consuming pathological analysis are requir...

Five of 33 patients with dermatitis herpetiformis (DH) were found to have gastric parietal cell antibody in their sera, whereas it was not found in 30 healthy controls of comparable age distribution. Fifteen of the patients with DH underwent further studies to investigate the histological and functional state of their gastric mucosa. Atrophic gastritis was found in all five patients whose sera ...

Ethanol has been found to induce ulcerative gastric lesion in humans. The present study investigated the in vivo protective effect of astaxanthin isolated from the Xanthophyllomyces dendrorhous mutant against ethanol-induced gastric mucosal injury in rats. The rats were treated with 80% ethanol for 3 d after pretreatment with two doses of astaxanthin (5 and 25 mg/kg of body weight respectively)...
