We report successfully treating a rare case of recurrent solitary tumor in the rectovesical extraperitoneum. A 68-year-old man undergoing right hemicolectomy for ascending colon cancer in 2001 was found in pelvic computed tomography in October 2003, conducted to evaluate a tumor marker increase, to have a 16 mm tumor behind a seminal vesicle touching the rectum. Endoscopic biopsy showed well-differentiated submucosal adenocarcinoma, necessitating low anterior resection. Surgical findings indicated the tumor had invaded to Rb of the rectum, but, showed nothing unusual in the rectovesical pouch. Microscopic findings in the resected specimen suggested invasion from outside the intestinal wall because rectal mucosa was intact. The man has shown no sign of recurrence in the more than 5 years since the last surgery.
