Glomus tumors are rare, mesenchymal neoplasms of adulthood, which occur in both the sexes with equal frequency. Most of these tumors are benign, but some cases with atypical/malignant behavior have been reported. They most often occur in the extremities, typically in the subungual region of the fingers, and rarely involve the internal organs. We report the case of a 63-year-old man who presented with hematuria. The cystoscopy showed a polypoid lesion of the anterior wall of the bladder, which was diagnosed on biopsy as a benign glomus tumor. To the best of our knowledge, this is the first case of benign glomus tumor of the bladder described in the literature. This report widens the spectrum of the differential diagnoses of bladder neoplasms.
血管球瘤是一种罕见的成年间叶性肿瘤，男女发病比例相当。大多数血管球瘤为良性，但也有部分病例表现出非典型/恶性行为。这些肿瘤多发生于四肢，通常位于手指的甲下区域，很少累及内脏器官。我们报告 1 例 63 岁男性患者，因血尿就诊。膀胱镜检查显示膀胱前壁有一息肉样病变，活检诊断为良性血管球瘤。据我们所知，这是文献中首例描述的膀胱良性血管球瘤。本病例拓宽了膀胱肿瘤的鉴别诊断范围。
