We experienced three young patients with diffuse lymphoid hyperplasia of the gastric antrum. The peculiar nodularity of the stomach in tliese patients is another cause of etat mammelanne in addition to hypertrophic gastritis and prominence of the areae gastricae. The etiology of the diffuse lymphoid hyperplasia of the gastric antrum is not known. The symptqm is not specific and not related to hitologic and gastroscopic finding but rather to psychological disturbance. We propose longstanding observation for the change of the nodularity.

Gastritis cystica profunda is an uncommon benign mass that usually occurs on the gastric side of the site of a gastroenterostomy, but has also been known to develop in which has not been operated on. We report the case of stomach a 51-years-old man with pathologically proven gastritis cystica profunda. This patient had not undergone gastric surgery and CT showed a well-defined, 3 cm sized, cystic mass at the gastric antrum.

Double pylorus is a rare disease. It is described by a double communication between the gastric antrum and the duodenal bulb. The cause of double pylorus is either a congenital abnormality or an acquired condition. It is believed to be mostly a complication of peptic ulcer disease. Most reports revealed conditions only for the gastric antrum. However, case reports describing the involvement of the gastric body are extremely rare. Herein, we report a case of a double pylorus that developed on the gastric body and we present a review of the literature.

Gastroduodenal fistula or double pylorus is a very rare condition. It is a fistulous communication between gastric antrum and duodenal bulb. It can be either congenital or acquired. In most cases it is thought to be a complication of gastric ulcer. We recently experienced a case of gastroduodenal fistula in 70 year-old man presenting as epigastric pain. He was diagnosed with non ST elevation myocardial infarction previously, and was taking aspirin. Gastroduodenal communication was revealed by endoscopy. We report a case of gastroduodenal fistula that developed in man who was taking aspirin, with review of the literature.

Gastric antral vascular ectasia ("watermelon stomach") is characterized by a prominent longitudinalerythematous fold of gastric antrum. Because it has usually been diagnosed by gastroscopy and biopsy, itsradiologic findings have not been well described. We report a case of gastric antral vascular ectasia, anddescribe its findings, as seen on UGIS, ultrasonography, and computed tomography.

Gastroduodenal intussusception is a rare condition and an invagination of a part of the gastric wall through the pyloric canal and into the duodenum. Gastroduodenal intussusception is always caused by a mobile gastric tumor, usually benign. However, gastroduodenal intussusception which was caused by gastric submucosal hemangiomatosis is not documented. We have maneged a case of gastric submucosal tumor leading to gastroduodenal intussusception in 2 years and 10 months old boy. He had a 10 x 5 x 3 cm sized submucosal tumor in posterior wall of gastric antrum. Laparotomy, manual reduction of intussusecption, and wedge resection of posterior gastric wall including the submucosal tumor were performed. Pathologic diagnosis showed a submucosal hemangiomatosis. We report a case of gastric submucosal tumor leading to gastroduodenal intussusception, and review the literature.

Inflammatory fibroid polyp(IFP) typically prescnts as a polypoid mass in the gastric antrum. Radiologically and endoscopically, it can be confused with polypoid carcinoma or submucosal stromal tumor. The histogenetic origin of IFP has been controversial, but it is considered as a reactive lesion of the myofibroblastic nature. IFP is rarely concomitant with gastritis cystica profunda(GCP) which is also one of the nonneoplastic inflammatory polyps. We report a case of IFP associated with GCP presenting as a large polypoid mass in the previously unoperated stomach of a 78-year-old woman. The mass was mainly located in the submucosa of the antrum and the cut surface exhibited a myxoid and glistening appearance with partial cystic change. Histologically, the mass showed marked proliferation of spindle cells, small blood vessels and many inflammatory cells, especially eosinophils. Also, there were many variable sized glands composed of gastric foveolar epithelia within the mass. In conclusion, the rarity of these two associated lesions in the present case may cause difficulty in diagnosis, and therefore recognition about these lesions is needed. In addition, this case supports the nature of IFP as being reactive rather than neoplastic.

Dieulafoy's lesion is a rare distinetive arterial malformation that can cause massive gastrointestinal henorrhage. Although in most cases the lesion is encountered in the proximal stomach within 6 cm of the gastroesophageal junction, similar lesions have been described in the antrum, duodenum, jejunum, colon, and rectum. We report 3 unusually located Dieulafoy-like lesion, two gastric antrum and one jejunum in patient who had gastrojejunostomy for pancreatic caneer. After a year follow up there was no bleeding episode in patient after endoscopic treatment.

Malignant transformation of heterotopic pancreas is extremely rare. We report a case of ductal adenocarcinoma arising from heterotopic pancreas in the stomach of a 64-year-old man. Preoperative CT scans showed the lesion as a submucosal mass along the greater curvature of the pyloric antrum and protruding into the pyloric canal. After gastric surgery, the resected tumor was histopathologically diagnosed as a ductal adenocarcinoma arising from heterotopic pancreas with cystic dilatation of aberrant pancreatic duct.

It is known that multiple ulcers of the gastric antrum are often accompanied by marked submucosal fibrosis during the healing process, and that this may result in a deformity of the gastric wall. Thus, benign antral ulcers may be misinterpreted as intramural tumors, or even malignant ulcers when the surrounding edema is pronounced and sharply defined. It is possible for an endoscopic ultrasonography (EUS) to detect which layer has a submucosal tumor (SMT) in the five-layer structures of the digestive tract wall. In the diagnosis of SMT of the upper digestive tract, EUS allows for the visualization of the structures underlying the gastrointestinal wall in a noninvasive manner and has a great advantage over conventional modalities such as endoscopy and X-ray examination. The EUS findings of 2 cases of submucosal tumor-like gastric lesion caused by fibrotic ulcer healing are herein reported with a brief review of relevant literature.
