Abstract
A 63-year-old man was admitted to the hospital because of a 3-day history of severe right lateroabdominal pain and persistent diarrhea lasting for half a month. Enhanced abdominal CT scan showed a pericecum abscess. The pain was localized at the right lower quadrant of abdomen, with tenderness, muscle guarding and rigidity. We thus diagnosed the case as localized peritonitis caused by perforation of the appendix. He had an emergency operation for abdominal abscess and ileocecal resection was done. Desmoid tumor was diagnosed based on postoperative histologial examination that was supported by positive immunohistochemical stainings for vimentin and β catenin. The postoperative course was uneventful and he was discharged on the 14th postoperative day. There has been no evidence of recurrence for 23 months.
Desmoid tumors after recur in a high rate even after complete resection and further careful follow-up would be necessary.
