Hyperplastic or adenomatous polyps have been previously described in both human medicine and domestic species (Crawford 1999). This condition has been most frequently reported in cats (Orr et al. 1980) and also in dogs and sheep (Barker et al. 1993). To date, only one report of an adenomatous polyp in the equine species exists (Patterson-Kane et al. 2000). To the authors’ knowledge, an intussus...

Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...

An 81-year-old woman presented for colonoscopy because of iron deficiency anemia. She had undergone colonoscopy 5 years previously during which a 2-cm prominent fold had been identified in the proximal ascending colon (●" Fig.1). A biopsy of this lesion was interpreted as being a hyperplastic polyp (●" Fig.2), although the polyp showed features of a serrated lesion. Because of clinical concern ...

Gastric hyperplastic polyps are often asymptomatic and are found incidentally at upper endoscopy performed for unrelated reasons. Although they are considered a benign lesion, all symptomatic polyps should be removed for a more reliable histological diagnosis, resolution of symptoms and to prevent potential malignant transformation. In fact, there are no significant difference between pure gast...

AIMS To describe the clinical and pathological features of 10 further cases of fibroblastic polyps (FP), a recently described, distinctive type of colorectal mucosal polyp. METHODS AND RESULTS The patients were seven women and three men with ages ranging from 44 to 63 years. The lesions ranged in size from 2 to 4 mm. Eight of the polyps were located in the sigmoid colon. Five cases were assoc...

Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Although, the underlying mechanism of carcinogenesis in gastric hyperplastic polyps is still uncertain, most malignant polyps are seen to originate from dysplastic epithelium rather than from hyperplastic epithelium. Herein, we report the case of a woman diagnosed with ...

A 52-year-old woman consulted a local physician because of epigastric pain. Upper gastrointestinal endoscopy showed a slightly elevated polyp, about 10 mm in diameter, in the anterior wall of the upper gastric body. The patient was therefore referred to the Department of Gastroenterology, Kitasato University East Hospital. Helicobacter pylori was negative, and there was no atrophy of the gastri...

Polypectomy is the standard therapy for gastrointestinal pedunculated polyps [1]. However, achieving effective countertraction to snare the stalk of the polyp located in the direction of gravity can sometimes be difficult [2]. Herein, we present a case of a large gastric polyp located on the greater curvature of the gastric body that was resected using the “water immersion” technique in order t...

BACKGROUND The purpose of this study was to determine the frequency of Serrated polyps of colonic polyps samples in Hazrat_e Rasoul_e Akram Hospital over ten years. MATERIALS The target group in this study was patients with colonic polyps in Hazrat_e Rasoul_e Akram Hospital. Pathologic evaluation of these patients was done. Serrated polyps, by location, gender, age and type of polyps were div...
