Abstract: | An 11-week-old male entire French Bulldog was presented with a 3-week history of projectile vomiting after eating that was unresponsive to medical therapy. Ultrasonographic examination revealed a 1 × 2 cm pedunculated polypoid mass in the pyloric antrum. Histopathology showed this to be comprised of a pedunculated hyperplastic proliferation of gastric mucosal epithelium and submucosa, with dilatation of the glandular pits and a moderate degree of submucosal fibrosis and small amount of smooth muscle hyperplasia in the submucosa. The tunica muscularis was not involved in the polyp and appeared to be of normal thickness. Surgical treatment by pylorectomy and end-to-end gastroduodenostomy (Billroth I) was successful. |
