*Article is in Japanese* An 84-year-old man underwent laparoscopic descending colon resection for colon cancer with stage â… . Follow-up computed tomography(CT), 18 months after surgery showed a soft tissue density nodular mass, 30 mm in size, in the small intestinal mesentery. The surgical resection of the tumor was performed after a thorough examination. Histopathological examination showed spindle-shaped fibroblasts and abundant collagen fibers. Immunohistochemical staining was negative for c-kit and CD34 and positive for Î±-SMA and Î²-catenin. From the above, this tumor was diagnosed as intra-abdominal desmoid tumor.
