In the worldwide medical literature, only one case of inlet patch shows a kissing pattern on endoscopy. This article describes 69-year-old female patient who came to gastroenterology clinic, Rohani hospital, Babol University Medical Sciences (Iran) for an examination indigestion. Endoscopy showed two polyps in background maroon just below upper esophageal sphincter, oppositely positioned view p...

Gastroduodenal intussusception is an infrequent cause of gastrointestinal obstructive disease. Benign neoplasms, gastrointestinal stromal tumors and pedunculated adenocarcinomas of less than 5 cm have been reported to cause gastroduodenal intussusception. We report a case of 76-year-old woman who was presented with a 3-day history of nausea and vomiting due to upper gastrointestinal obstruction...

We present herein the occurrence of multifocal adenocarcinomas with a minute signet ring cell carcinoma that arose within a gastric inverted hyperplastic polyp (IHP) in a 40-year-old woman. Endoscopic ultrasonography demonstrated a heterogeneous hypoechoic mass in the third layer of the gastric wall. The endoscopic submucosal dissection specimen measuring 3.5×3.2×1.8 cm was a well-circumscribed...

Inflammatory fibroid polyp (IFP) is a rare solitary gastrointestinal lesion of unknown etiology. It generally presents as polypoid mass in the gastric antrum. Mostly affects adults at average age of 60 years. IFP can cause different symptoms such as abdominal pain, gastrointestinal bleeding, intestinal obstruction or intussusception. IFP is a bening lesion and it may rarely mimic the submucosal...

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 origina...

Benign polyps of the stomach undergo malignant transformation at a rate correlating to the histological type and size of the proliferative lesion. We report a case of a 50-year-old Caucasian woman, affected by a diffuse gastric polyposis of both hyperplastic and adenomatous type. At endoscopy polyps were more than 1,000, scattered over the entire gastric cavity. The patient underwent total gast...

Gastric precancerous diseases (GPD) may deteriorate into early gastric cancer if misdiagnosed, so it is important to help doctors recognize GPD accurately and quickly. In this paper, we realize the classification of 3-class GPD, namely, polyp, erosion, and ulcer using convolutional neural networks (CNN) with a concise model called the Gastric Precancerous Disease Network (GPDNet). GPDNet introd...
