To report two additional cases of carcinosarcoma of the bladder and review the literature.
METHODS/RESULTS: Two cases of bladder tumor are described. Both patients were male whose median age at diagnosis was 69.5 years. They had consulted for post-void hypogastric pain and hematuria. A diagnosis of bladder tumor was made on the basis of the radiological and ultrasound findings and a partial cystectomy was performed. Histological examination with immunohistochemical techniques revealed carcinosarcoma of the bladder.
Carcinosarcoma is a mixed tumor with a high grade of malignancy and is rarely located in the bladder. Its clinical presentation is not unlike that of other bladder tumors. Diagnosis is always by histology using immunological techniques. It has a very poor prognosis. Because it is a rare tumor type, its natural history is unknown and treatment remains unclear, although radical surgery continues to be the most widely utilized.
报告另外两例膀胱癌肉瘤病例并复习相关文献。
方法/结果：描述了两例膀胱肿瘤病例。两名患者均为男性，诊断时的中位年龄为69.5岁。他们因排尿后下腹部疼痛和血尿前来就诊。根据放射学和超声检查结果诊断为膀胱肿瘤，并进行了部分膀胱切除术。采用免疫组织化学技术进行组织学检查显示为膀胱癌肉瘤。
癌肉瘤是一种高度恶性的混合性肿瘤，很少发生于膀胱。其临床表现与其他膀胱肿瘤并无不同。诊断始终依靠免疫技术进行组织学检查。其预后非常差。由于它是一种罕见的肿瘤类型，其自然病程尚不清楚，治疗方法也不明确，尽管根治性手术仍然是应用最广泛的治疗方法。
