尽管已有100多例膀胱血管瘤的报道，但毛细血管型膀胱血管瘤很少见。化脓性肉芽肿是皮肤和口腔粘膜常见的肿瘤样血管病变，其组织病理学表现与毛细血管型血管瘤相似，在临床特征和病因方面与普通血管瘤不同。关于膀胱化脓性肉芽肿的发生知之甚少。我们介绍了一名 78 岁日本男性的病例，他的膀胱出现血管瘤病变，导致急性血栓滞留。他最近有胰腺癌化疗史。在膀胱中观察到一个1.2cm的孤立的带蒂肿块。切除肿块的组织病理学分析显示小叶毛细血管明显增生并伴有表面糜烂。除了可能的诱发因素之外，膀胱镜和病理结果也支持膀胱化脓性肉芽肿的诊断。
Although more than 100 cases of hemangioma of the urinary bladder have been reported, capillary-type hemangiomas of the bladder are rare. Pyogenic granulomas, which are common tumor-like vascular lesions of the skin and oral mucous membranes, reveal histopathological findings similar to capillary-type hemangiomas and are differentiated from ordinary hemangiomas by clinical features and etiologic factors. Little is known regarding the occurrence of pyogenic granulomas in the urinary bladder. We present the case of a 78-year-old Japanese man who had developed a hemangiomatous lesion in his bladder which led to acute clot retention. He had a recent history of chemotherapy for pancreatic cancer. A solitary pedunculated mass measuring 1.2 cm was observed in the bladder. Histopathological analysis of the resected mass revealed marked lobular capillary proliferation with surface erosions. Cystoscopic and pathologic findings in addition to possible predisposing factors supported a diagnosis of pyogenic granuloma of the urinary bladder.
