Small bowel hemorrhage is responsible for approximately 4% of all cases of gastrointestinal bleeding. The etiology of bleeding from the small bowel is a tumour in approximately 10% of cases. Pyogenic granuloma is a common inflammatory vascular tumour of the dermis, which rarely occurs in the gastrointestinal tract. Pyogenic granuloma is a rare cause of overt or obscure small bowel bleeding. The present paper reports the first case of pyogenic granuloma presenting as a massive gastrointestinal bleed, and reviews the relevant literature to date regarding the clinical presentation, diagnosis and management of this rare gastrointestinal lesion.
小肠出血约占所有胃肠道出血病例的4%。小肠出血的病因在约10%的病例中为肿瘤。化脓性肉芽肿是真皮常见的炎症性血管肿瘤，很少发生于胃肠道。化脓性肉芽肿是显性或隐匿性小肠出血的罕见原因。本文报告首例以大量胃肠道出血为表现的化脓性肉芽肿病例，并回顾了迄今为止关于这种罕见胃肠道病变的临床表现、诊断和管理的相关文献。
