Transitional cell carcinoma of the urethra [correction of ureter] in a patient with buttock pain: a case report.

This case reports on a patient with an unusual presentation of a rare tumor: urethral transitional cell carcinoma (TCC). Urethral TCC occurs in approximately 0.7% to 4.0% of patients who have had primary bladder cancer. The initial symptoms usually involve hematuria, with approximately a third of patients reporting flank area pain. Buttock pain and the absence of hematuria are uncommon with this disorder. The patient was initially suspected to have piriformis syndrome, but when he did not respond as expected to treatment, and because of his history of primary bladder cancer, further evaluation was undertaken and the diagnosis was made. The patient responded well to radiation and chemotherapy. Musculoskeletal physicians should be particularly suspicious of the presence of urethral TCC in a patient with a history of primary bladder cancer who reports low back or buttock pain, particularly if the patient does not respond quickly to treatment.
