SYNCHRONOUS GROWTH OF A MESODERMAL MIXED TUMOR AND AN ADENOCARCINOMA IN THE BLADDER

The case of sychronous growth of a mesodermal mixed tumour and an aden ocarcinoma in the bladder is presented. This is a rare phenomenon. Mes odermal mixed tumours are malignancies with both epithelial (carcinoma ) and mesenchymal (sarcoma) differentiation. The term carcinosarcoma i s frequently used in the literature. In most cases the prognosis of me sodermal mixed tumours, which depends mainly on the high rate of local recurrences, is poor. Therefore, cystectomy with suprapubic urinary d iversion is the treatment of choice. However, results reported in the literature show that transurethral resection of the tumour may be adeq uate when there is only superficial growth of mesodermal mixed tumours . Short follow-up intervals are absolutely essential for patients trea ted this way.
