Gastric carcinoma in a dog

An 8–year-old castrated male Bassett hound had been vomiting intermittently for 3 weeks. In addition, clinical signs of anorexia, weight loss, dehydration, depression and anterior abdominal pain were noted. Gastro-scopic and radiographic examination revealed a mass at the pyloric region of the stomach. Clinical remission followed surgical excision of gastric carcinoma, with recurrence of vomiting 4 months after surgery. At necropsy, the pyloric region of the stomach was markedly thickened, rigid, scirrhous and had an excavated ulcer. The pathological diagnosis was a poorly differentiated, diffuse gastric carcinoma with metastasis to regional lymph nodes.
