Metastasis to Sartorius Muscle from a Muscle Invasive Bladder Cancer

الملخص EN

Bladder cancer constitutes the ninth most common cancer worldwide and approximately only 30% of cases are muscle invasive at initial diagnosis.

Regional lymph nodes, bones, lung, and liver are the most common metastases from bladder cancer and generally from genitourinary malignancies.

Muscles constitute a rare site of metastases from distant primary lesions even though they represent 50% of total body mass and receive a large blood flow.

Skeletal muscles from urothelial carcinoma are very rare and up to date only few cases have been reported in the literature.

We present a rare case of 51-year-old patient with metastases to sartorius muscle 8 months after the radical cystectomy performed for a muscle invasive bladder cancer.
