Skeletal metastasis of transitional cell carcinoma of the urinary bladder is very rare. Bladder cancer mostly metastases to lymph nodes, lung, liver, bone and adrenal glands. In this article, a 59-year-old male patient, who had been diagnosed as having a bladder tumor 2 years previously at another center, was presented. Two years earlier, transuretral bladder tumor resection had been performed to the patient and the tumor had been diagnosed as muscle invasive bladder tumor pathologically. After the diagnosis, definitive radiotherapy and systemic chemotheraphy treatment was performed. During routine follow-up procedure, in the investigations which were carried out because of right gluteal pain, gluteus muscle metastasis was diag- nosed. During the next follow-up procedures, systemic metastasis occurred and the patient died 6 months later.
