The case of synchronous growth of a mesodermal mixed tumour and an adenocarcinoma in the bladder is presented. This is a rare phenomenon. Mesodermal mixed tumours are malignancies with both epithelial (carcinoma) and mesenchymal (sarcoma) differentiation. The term carcinosarcoma is frequently used in the literature. In most cases the prognosis of mesodermal mixed tumours, which depends mainly on the high rate of local recurrences, is poor. Therefore, cystectomy with suprapubic urinary diversion is the treatment of choice. However, results reported in the literature show that transurethral resection of the tumour may be adequate when there is only superficial growth of mesodermal mixed tumours. Short follow-up intervals are absolutely essential for patients treated this way.
本文报道了1例膀胱中胚叶混合瘤与腺癌同步生长的病例。这是一种罕见的现象。中胚叶混合瘤是一种具有上皮（癌）和间叶（肉瘤）分化的恶性肿瘤。文献中常使用“癌肉瘤”这一术语。在大多数情况下，中胚叶混合瘤的预后较差，主要取决于局部复发率高。因此，耻骨上尿路改道术的膀胱切除术是首选的治疗方法。然而，文献报道显示，当中胚叶混合瘤仅为浅表生长时，经尿道肿瘤切除术可能就足够了。对于采用这种方法治疗的患者，绝对需要短的随访间隔。
