A 71-year-old man with pathological Stage Ⅰ(pT1bN0M0)underwent laparoscopic sigmoid colon cancer resection. After 18 months postoperatively, follow-up computed tomography(CT)showed a 30 mm enhanced soft tissue tumor near the anastomotic site. Considering the magnetic resonance imaging(MRI)and positron emission tomography(PET)results, we diagnosed sigmoid colon cancer with local recurrence. Laparoscopic radical resection of the colon and intestine, including the tumor, was performed. Pathologically, the tumor comprised spindle-shaped cells with collagen fibers and was diagnosed as a desmoid tumor by immunostaining(β-catenin+, c-kit-, CD34-, α-SMA-, and DOG-1-). We report a case of intra-abdominal desmoid tumor near the anastomotic site after laparoscopic sigmoid colon cancer resection.
一名71岁的男性患者，病理分期为Ⅰ期（pT1bN0M0），接受了腹腔镜乙状结肠癌切除术。术后18个月，随访计算机断层扫描（CT）显示吻合口附近有一个30毫米的强化软组织肿瘤。结合磁共振成像（MRI）和正电子发射断层扫描（PET）结果，我们诊断为乙状结肠癌局部复发。遂进行了包括肿瘤在内的腹腔镜结肠和肠道根治性切除术。病理检查显示，肿瘤由含有胶原纤维的梭形细胞组成，免疫染色（β-连环蛋白阳性、c-kit阴性、CD34阴性、α-平滑肌肌动蛋白阴性和DOG-1阴性）诊断为硬纤维瘤。我们报告一例腹腔镜乙状结肠癌切除术后吻合口附近腹腔内硬纤维瘤的病例。
