Abstract:
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.
摘要:
1例71岁病理Ⅰ期(pT1bN0M0)患者行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)显示吻合部位附近30mm增强的软组织肿瘤。考虑磁共振成像(MRI)和正电子发射断层扫描(PET)的结果,我们诊断乙状结肠癌局部复发。腹腔镜结肠和肠根治术,包括肿瘤,已执行。病理上,肿瘤由具有胶原纤维的梭形细胞组成,通过免疫染色诊断为硬纤维瘤(β-catenin,c-kit-,CD34-,α-SMA-,和狗-1-)。我们报告了一例腹腔镜乙状结肠癌切除术后吻合口附近的腹内硬纤维瘤。
