【 摘 要 】

The coexistence of 2 primary bladder tumors of different histogenesis is very rare. Synchronous leiomyosarcoma LMS of the bladder and urothelial carcinoma are even rarer. We report here the case of a 48-year-old patient who presented with hematuria and symptoms of bladder irritation . Cystoscopy showed a superficial bladder tumor which occupies the entire bladder lumen. Transurethral resection of bladder tumor (TURBT) was performed and revealed a noninvasive low-grade papillary urothelial carcinoma pTa with nonvisualized muscularis. A second TURBT could not remove any muscle. The decision for a radical cystectomy was performed with Bricker derivation and pelvic lymph node dissection to control bleeding. The final pathology demonstrated concurrent urothelial carcinoma and leiomyosarcoma LMS. In this report, we presented a unique case of urinary bladder leiomyosarcoma with noninvasive urothelial carcinoma. The rarity of this association and its clinical similarity to other common tumors, including infiltrative urothelial tumors , leading to misdiagnosis, are also described.
