title: An unusual case of chronic anal pain--a pin in the bum?
abstract: We report the case of a 70-year-old woman who had previously undergone anterior resection in 2001 for a diverticular stricture. Bleeding from pelvic veins intra-operatively necessitated the use of two thumbtacks to aid haemostasis. Over the next 7 years, she presented repeatedly with anal pain, bleeding and mucus discharge per rectum. Multiple lower gastrointestinal endoscopies failed to make a definitive diagnosis until a single thumbtack was found eroding through the rectal mucosa. This was removed and she has been subsequently asymptomatic. This condition was clearly difficult to diagnose and requires a high index of suspicion in those patients who have previously undergone pelvic surgery.
