Gastric protruding lesions are frequently encountered by health screening esophagogastroduodenoscopy. They can be classified into epithelial lesion and subepithelial lesion. Epithelial gastric lesions are generally divided into benign and malignant. Benign lesions include some types of polyps, i.e., hyperplastic polyp, fundic gland polyp, and gastric adenoma. Malignant lesions include carcinoid...

A 73-year-old man was admitted to our hospital with complaints of tarry stools. He had been receiving warfarin anticoagulant therapy for severe left ventricular dysfunction. Prothrombin time international normalized ratio had been maintained within 2.0-3.0. Esophagogastroduodenalscopy revealed a polypoid lesion about 10 mm in diameter on the greater curvature of the stomach with oozing (Picture...

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...

chronic hyperplastic pulpitis (pulp polyps) usually occurs in molar teeth of children and young adults and is characterized by an overgrowth of granulomatous tissue into the carious cavity. here, we report a rare type of pulp polyp in lower third molar of a 27-year-old woman that not only grow into carious cavity but also extruded in very large size that interfered with occluding of the teeth.

Pseudomelanosis is a rare endoscopic finding of the upper gastrointestinal tract characterized by hemosiderin deposits in histiocytes of lamina propria. We report a case of 72-year-old lady on chronic oral iron supplementation diagnosed with gastric hyperplastic polyps with background pseudomelanosis of stomach and duodenum. Concomitant occurrence of gastric pseudomelanosis, duodenal pseudomela...

Watanabe et al. [3] first reported a case of juvenile polyposis of the stomach in 1979. Since after, it was proposed as the fourth category of juvenile polyposis [4]. Juvenile polyposis of the stomach is, however, difficult to diagnose because of rare phenotype and difficulty of differential diagnosis between juvenile polyp and foveolar hyperplastic polyp histologically by biopsy specimens. We ...

Hyperplastic polyps are lesions that are mostly smaller than 1 cm; they are sessile and innocuous. They develop as a result of tissue damage and an exaggerated mucosal regeneration. Intestinal metaplasia and dysplasia at a rate of 1–20% may be seen in hyperplastic polyps. However, the risk of carcinoma development is less than 2%. The risk increases in multiple polyps (1). Here we present a cas...

A fibro-epithelial polyp is the most common epithelial benign tumor of the oral cavity. Such a polyp is of mesodermal origin and it is a pink, red, or white knob-like painless growth that is sessile or pedunculated. A fibro-epithelial polyp commonly occurs on buccal mucosa, the tongue, or the gingiva. A fibro-epithelial polyp is an inflammatory hyperplastic lesion in response to chronic irritat...
