- Abstract: Hematogenous metastasis to skeletal muscle from urothelial carcinoma is extremely rare and metastatic disease to skeletal muscle tends to be found in people with advanced-stage neoplasm. We report in this paper a case of left sartorius muscle metastasis from urothelial cell carcinoma. A left nephroureterectomy with bladder cuff excision was performed and revealed a high-grade papillary transitional cell carcinoma (TCC) of the pelvis. And 6 month later, recurrent bladder cancer was found regular cystoscopy and then treated with transurethral resection of the bladder. After 6 times resection of bladder, an invasion into the bladder muscle layer was found. We recommended additional radical cystectomy to prevent the disease from advancing. However, the patient refused additional surgery. 6 month later, the patient complained of left thigh pain, so ultrasonography-guided biopsy of the nodular mass lesion in the left sartorius muscle was performed. The pathological analysis of the biopsy specimen revealed poorly differentiated metastatic urothelial carcinoma.
