We report a 50 year old male who presented with a short history of gross hematuria. An ultrasonogram detected a mass arising from the right lateral wall of the urinary bladder. Computed tomography of the abdomen revealed that the mass was a calcified lesion mimicking a bladder stone. Cystoscopy confirmed the presence of the calcified lesion and biopsy revealed a rare biphasic tumor of the urinary bladder comprising of osteosarcoma and a papillary urothelial neoplasm of low malignant potential. The rarity of this tumor and its associated exuberant calcification make this case an interesting one.
我们报告了一名50岁男性，其出现肉眼血尿病史较短。超声检查发现膀胱右侧壁有一肿块。腹部计算机断层扫描显示该肿块为钙化病变，类似膀胱结石。膀胱镜检查证实了钙化病变的存在，活检显示为一种罕见的膀胱双相肿瘤，由骨肉瘤和低恶性潜能的乳头状尿路上皮肿瘤组成。这种肿瘤的罕见性及其相关的大量钙化使得该病例很有趣。
