A 48-year-old woman presented with an abdominal tumor. On abdominal computed tomography, a tumor measuring 50 mm in diameter was seen on the left side of the mesentery. We performed laparoscopy-assisted partial resection of the small bowel for diagnosis/treatment of the mesenteric tumor. Histopathologically, the tumor showed fibroblastic growth. Immunohistochemistry showed negative staining for c-kit, but positive staining for β-catenin. Based on the findings, the patient was diagnosed as having a desmoid tumor. The surgical margin was negative. Although complete resection of an intraabdominal desmoid tumor has been reported to be difficult, we were able to diagnose and completely resect the tumor by laparoscopic-assisted surgery in our patient.
