Background and Objectives: Gastrointestinal polyps are proliferative or neoplastic mucosal lesions. The most important point about these polyps is risk of malignancy of them. This study was performed to determine type and frequency of polyps of gastrointestinal tract in Iranian population according to their locations. Materials and Methods: Totally, 210 patients referred to Rasul-e-Akram Hospi...

The author investigated histopathology of 615 consecutive duodenal specimens in our pathology laboratory. Computer search of the duodenal lesions was performed. Review of histological slides was done, when appropriate. The duodenal specimens were composed of 567 benign lesions and 48 malignant lesions. The 567 benign lesions were composed of chronic non-specific duodenitis in 334 cases (60.0%),...

Gastric hamartomatous inverted polyp (HIP) is difficult to diagnose preoperatively because of its rarity [1,2]. It is pathologically benign, but has been reported as a paracancerous lesion [3–5], and therefore its diagnosis and treatment are clinically important. We report a case of gastric HIP and focus on its special characteristics on endoscopy and endosonography. An 18-mm submucosal tumor w...

Inflammatory fibroid polyps are very rare gastrointestinal tumors. We present the case of a 66-year-old woman with severe anemia and giant gastric polyp which had intermittent duodenal intussusception. Ultrasonography showed increased wall thickness suspected an ampulloma, as revealed also by endoscopy computed tomography. reassessment later intragastric mass, was confirmed endosonography: pedi...

A 46-year-old woman underwent upper endoscopy for persistent nausea. Endoscopic examination of the stomach revealed prominent gastric folds in the gastric body. Biopsy by cold forceps demonstrated hyperplastic mucosa with ulceration (Figure 1). Endoscopic ultrasound (EUS) revealed a 45-mm sessile polyp with bleeding in the anterior wall of the gastric body (Figure 2). Endoscopic mucosal resecti...
