An 11-year-old castrated male Shih Tzu was referred for lethargy and melena. The hematocrit level was 18.8% (normal range: 36-56%), indicating severe anemia. Abdominal ultrasound revealed a round-to-oval-shaped mass in the stomach. Computed tomography (CT) revealed an intraluminal mass (17 × 12 × 15 mm) cranial to the pyloric antrum. After obtaining informed consent from the owner, exploratory laparotomy and subsequent gastrostomy were performed, showing an ulcerated mass potentially responsible for the severe anemia. A lump of hair was firmly attached to the ulcerated surface of the mass. After complete removal of the mass, the anemia resolved spontaneously. Histological examination revealed that the mass was a gastric hyperplastic polyp. At the 6-month follow-up, the dog was healthy with a normal hematocrit level. Gastric hyperplastic polyps are tumor-like lesions arising from the mucosal surface of the stomach, and projecting into the lumen. They can appear in any part of the stomach, and are usually found incidentally during gastric endoscopy or necropsy. The clinical signs include chronic occult blood loss, abdominal pain, and gastric tract obstruction. Gastric polyps causing acute blood loss anemia have rarely been reported in human medicine. To our knowledge, this is the first report describing a gastric hyperplastic polyp that caused severe anemia because of acute blood loss in a dog.
一只11岁去势雄性西施犬因嗜睡和黑便前来就诊。血细胞比容水平为18.8%（正常范围：36 - 56%），表明存在严重贫血。腹部超声显示胃内有一个圆形至椭圆形肿块。计算机断层扫描（CT）显示幽门窦前方有一个腔内肿块（17×12×15毫米）。在获得主人的知情同意后，进行了剖腹探查术及随后的胃造口术，发现一个溃疡肿块可能是导致严重贫血的原因。一团毛发牢固地附着在肿块的溃疡表面。肿块完全切除后，贫血自行缓解。组织学检查显示该肿块为胃增生性息肉。在6个月的随访中，这只狗健康，血细胞比容水平正常。胃增生性息肉是起源于胃黏膜表面并向腔内突出的肿瘤样病变。它们可出现在胃的任何部位，通常在胃镜检查或尸检时偶然发现。临床症状包括慢性潜血、腹痛和胃肠道梗阻。在人类医学中，很少有关于胃息肉导致急性失血贫血的报道。据我们所知，这是第一份描述一只狗因急性失血导致严重贫血的胃增生性息肉的报告。
