Glomus tumor (GT), which are neoplasms of the glomus body, usually occur in the extremities, particularly under the nail bed. GT occurring in the bladder is very rare and has been reported as sporadic. In the present study, a rare case of bladder GT is reported and its clinical and histopathological characteristics are summarized by literature review.
A 57-year-old woman presented with intermittent gross hematuria for 2 years. Urinalysis displayed hematuria. The bladder ultrasound showed an avascular and homogeneous isoechoic polypoid mass with a maximum diameter of 6 mm at the right lateral wall of bladder. The bladder endoscopic examination showed a polypoid lesion, with a smooth surface, located in the right lateral wall. Then, a transurethral resection was performed, its histopathological features indicated a benign GT.
GT arising in the bladder is extremely rare, and only four cases have been identified in studies reported in English. It is difficult to diagnose bladder GTs according to their clinical features. The gold standard method used for their diagnosis is histopathology. However, it should also be considered in the differential diagnosis for bladder mass.
指发生于肌球（glomus）体的肿瘤，通常发生于四肢，特别是在甲床下面。发生于膀胱的血管球瘤非常罕见，并且被报道为散发性。在本研究中，报告了一例罕见的膀胱血管球瘤病例，并通过文献复习总结其临床和组织病理学特征。
一位 57 岁女性因间歇性肉眼血尿 2 年就诊。尿分析显示血尿。膀胱超声显示在膀胱右侧侧壁有一个无血管的、均匀的等回声息肉样肿块，最大直径为 6mm。膀胱内镜检查显示位于右侧侧壁的息肉样病变，表面光滑。随后进行了经尿道切除术，其组织病理学特征提示为良性血管球瘤。
发生于膀胱的血管球瘤极其罕见，在英文文献报道中仅识别出 4 例。根据其临床特征诊断膀胱血管球瘤很困难。用于诊断的金标准方法是组织病理学。然而，对于膀胱肿块，也应考虑到其鉴别诊断。
