A 56-year-old male who had underwent subtotal gastrectomy for early stomach cancer two years ago, was admitted to our hospital for the feel of egg-sized tumor at the right side lower abdomen.
  Barium  enema examination, colonoscopy and abdominal CT examination revealed submucosal solid tumor at the opposite side of ileo-cecal valve. Laparotomy was performed under the suspicion of the occurrence of malignant non-epithelial tumor or the reccurence of stomach cancer. Histopathology of the resected material, however, revealed mesenteric desmoid tumor.
  Desmoid tumor in cases without familial adenomatous polyposis coil (FAP) is extremely rate. It had been presumed that the current tumor arose in process of tissue restration.
