In any age group, gross hematuria is an alarming symptom. A variety of diseases, including urinary tract tumors, urinary tract infections, glomerulonephritis, urinary stone disease, and urinary trauma, can cause gross hematuria. Neoplasms of the urinary tract are definitely the most bothersome among the differential diagnoses. Fibroepithelial polyps (FEPs), in contrast, are mesodermal-originated rare and benign tumors that can be observed in the urinary tract. In this case report, we present a child with an FEP at the bladder neck that was referred because of gross hematuria. A 5-year-old boy presented with intermittent gross hematuria for 2 weeks. Ultrasonography showed a 2 × 1 cm mucosal surface-borne polypoid lesion at the trigon. Patient underwent cystoscopic evaluation that revealed a polypoid mass located at the bladder neck; however, there were no signs of bladder outlet obstruction in the bladder. Transurethral resection revealed an FEP. Hematuria should be evaluated carefully not only in adults but also in children. FEPs in bladder can mimic bladder carcinoma clinically and radiologically. It should be kept in mind in the differential diagnosis of bladder lesions on imaging modalities in pediatric population.
在任何年龄组中，肉眼血尿都是一个令人担忧的症状。多种疾病，包括泌尿系统肿瘤、泌尿系统感染、肾小球肾炎、尿路结石病和尿路创伤，都可导致肉眼血尿。在鉴别诊断中，泌尿系统肿瘤无疑是最麻烦的。相比之下，纤维上皮息肉（FEP）是起源于中胚层的罕见良性肿瘤，可在泌尿系统中观察到。在本病例报告中，我们介绍了一名因肉眼血尿转诊的膀胱颈FEP患儿。一名5岁男孩出现间歇性肉眼血尿2周。超声检查显示膀胱三角区有一个2×1厘米的黏膜表面带蒂息肉样病变。患者接受了膀胱镜检查，发现膀胱颈有一个息肉样肿物；然而，膀胱内没有膀胱出口梗阻的迹象。经尿道切除术显示为FEP。不仅在成人中，而且在儿童中也应仔细评估血尿。膀胱FEP在临床和影像学上可模仿膀胱癌。在儿科人群中进行膀胱病变的影像学鉴别诊断时应牢记这一点。
