Cutaneous perianal recurrence on the site of Lone Star Retractor after J-pouch coloanal anastomosis for rectal cancer: report of two cases.

Cutaneous perianal recurrence is rare after anterior resection for rectal cancer. In most cases, exfoliated tumor cells almost certainly seeded onto an area of anal canal that was injured by the head of the stapling gun used for the fashion of stapled colorectal anastomosis. The first two cases of cutaneous perineal recurrence on the site of a Lone Star Retractor after handsewn J-pouch coloanal anastomosis for rectal cancer are presented. In two cases, recurrence occurred on the scars induced by elastic stay hook of Lone Star retractor. Both cases were treated by local excision alone. At one year of follow-up, there were no signs of local recurrence.
