[Transurethral resection of a intravesical recurrence of a tumor after resection of sigmoid colon cancer].
A 66-year-old man presented to the urology clinic with hematuria. Cystoscopy with biopsy was performed for suspected bladder cancer, and a pathological diagnosis of adenocarcinoma was made. Colonoscopy revealed sigmoid colon cancer, and he was referred to our hospital. Computed tomography (CT) and magnetic resonance imaging (MRI) showed sigmoid colon cancer with urinary bladder invasion. Sigmoidectomy with lymph node dissection and partial cystectomy were performed under laparotomy. The pathological diagnosis was moderately differentiated adenocarcinoma: T4b (bladder), N1, M0, and the bladder margin was negative. Four months after surgery, CT revealed a small mass in the bladder. Cystoscopy showed a papillary pedunculated tumor at the bladder trigone, and a transurethral resection was performed. Pathological examination revealed a moderately differentiated adenocarcinoma, similar to the prior sigmoid colon cancer, which was diagnosed as an intravesical recurrence of the tumor. More than 8 years after the transurethral resection, the patient has shown no signs of recurrence.
