Pyogenic granuloma (PG), more accurately known as lobular capillary hemangioma, is a benign vascular tumor that usually occurs in the skin or oral mucosa. This lesion is rarely reported in the gastrointestinal tract but is known to bleed if not resected. We herein describe a case series with the clinical, endoscopic, and histologic findings of four cases of gastrointestinal PG at our institution. In addition, we provide a review of the literature and summation of all reported cases of PG specific to the gastrointestinal tract. Based on our experience, we suggest that the actual incidence of gastrointestinal PG may in fact be higher than reported because PG can be unrecognized or improperly diagnosed. It is important for the clinician to properly recognize this lesion as a source of anemia and its propensity to bleed during biopsy or resection.
化脓性肉芽肿（PG），更准确地称为小叶状毛细血管瘤，是一种通常发生于皮肤或口腔黏膜的良性血管肿瘤。这种病变在胃肠道中很少见报道，但已知如果不切除会出血。我们在此描述了一组病例，包括我们机构4例胃肠道PG的临床、内镜和组织学表现。此外，我们对文献进行了综述，并总结了所有报道的胃肠道特异性PG病例。根据我们的经验，我们认为胃肠道PG的实际发病率可能实际上高于报道，因为PG可能未被识别或诊断不当。临床医生正确认识这种病变作为贫血的一个来源及其在活检或切除过程中出血的倾向非常重要。
