Abstract:
Objective To investigate the histogenesis and clinicopathologic features of carcinosarcoma of the urinary bladder. Methods Two cases of carcinosarcoma (one man and one woman)were included.They were admitted to hospital with discontinuous,painless,macroscopic hematuria.Clinicopathalogic features of all findings of the 2 cases were reviewed. Results Cystoscopy of both cases showed that the tumors displayed polypous or cauliflower-like shape,and grew invassively.CT examination of the bladder wall confirmed the presence of parenchymatous tumor.Both of the 2 cases underwent partial cystectomy.Intraoperative examination showed the tumors were similar to carcinoma of bladder.Histopathology showed biphasic neoplasms with distinct high grade epithelial and mesenchymal components.Morphologic characteristic of the tumor was abnormally proliferative and the mitotic figures could be seen.One of the patients died within 11 months and the other,16 months following the operation. Conclusions Carcinosarcoma of the urinary bladder is a kind of rare malignant tumor that is most often in an advanced stage at presentation and has an unfavorable prognosis. It should be identified promptly and treated appropriately.Those who have discontinuous,painless,macroscopic hematuria should be warned of the risk of the disease.
