Pyogenic granuloma, also known as lobular capillary hemangioma, is a benign vascular tumor rarely found in the genitourinary tract. Here, we present a case of a 6-year-old boy presenting with gross hematuria who was found to have a mass at the bladder base on ultrasound. Endoscopic resection was performed, revealing the base of the mass originating from the prostatic urethra. Pathology found pyogenic granuloma. This entity has not previously been reported to arise from the pediatric urethra and should be considered on the differential for children presenting with gross hematuria and those found to have bladder or urethral masses.
脓性肉芽肿,也称为小叶性毛细血管瘤,是一种罕见于泌尿生殖道的良性血管肿瘤。在此,我们报告一例6岁男孩,因肉眼血尿就诊,超声检查发现膀胱底部有一肿块。进行了内镜切除,发现肿块基底起源于前列腺尿道。病理检查发现为脓性肉芽肿。此前尚无该病变起源于小儿尿道的报道,对于出现肉眼血尿以及发现膀胱或尿道肿块的儿童,应将其纳入鉴别诊断范围。
