Urethral recurrence of bladder tumor occurring as a perineal mass 2 years after transurethral resection: a case report.

Transitional cell carcinoma can develop as a multifocal tumor in the urinary system, especially in the bladder. Here, we report a 69-year-old man who had undergone transurethral resection for bladder tumor and had urethral recurrence that presented as a perineal mass 2 years after treatment. However, he had obtained normal cystoscopy, ultrasonography and computed tomography results at follow-up examinations.
