[Transitional cell carcinoma of the bladder in a young patient: a case report]

A 14-year-old male patient was admitted with the chief complaint of macroscopic hematuria. Abdominal ultrasonography demonstrated a tumor of the anterior wall of the bladder. Further, cystoscopic examination confirmed a papillary tumor. Transurethral resection of the bladder tumor was performed. Histopathology of the excised tumor showed transitional cell carcinoma (G1, pTa). Recurrence has not been observed for 9 months postoperatively.
