An 80-year-old man underwent laparoscopic assisted total gastrectomy for early gastric cancer, and the pathological stage was T1aN0M0 Stage IA. Follow-up CT scan, done 26 months after primary surgery, showed 75mm mass which was suspected to be intra-abdominal sarcoma in pelvic cavity. At laparotomy, the tumor had smooth surface and located at mesenterium, and we could completely resect the tumor combined with partial ileum. The postoperative immunohistochemical study showed positive staining of nuclear β-catenin expression. Therefore, we diagnosed the tumor as a desmoid tumor. Although desmoid tumors are frequently associated with episodes of antecedent trauma and surgical intervention, the relationship between desmoid tumors and laparoscopic surgery is unknown. After abdominal surgery, it is important to observe carefully with the possibility of occurrence of intra-abdominal desmoid tumor in mind.
