Tumor thrombus is an uncommon oncologic complication and is exceedingly rare in the setting of colorectal cancer. We present the case of a 71-year-old woman with a significant oncologic history, including rectal squamous cell cancer, who presented with left lower extremity deep vein thrombosis. She underwent left lower extremity venography and thrombectomy of the left common iliac vein. Pathologic examination revealed fragments of squamous cell carcinoma embedded in an organizing thrombus. A covered stent was placed in the common iliac vein across the internal iliac vein origin. Positron emission tomography-computed tomography confirmed mediastinal and retroperitoneal lymphadenopathy, which was managed with adjuvant carboplatin and paclitaxel chemotherapy.
肿瘤血栓是一种罕见的肿瘤并发症，在结直肠癌患者中极为罕见。我们报告一例71岁女性患者，她有重要的肿瘤病史，包括直肠鳞状细胞癌，此次因左下肢深静脉血栓形成就诊。她接受了左下肢静脉造影和左髂总静脉血栓切除术。病理检查发现鳞状细胞癌碎片嵌入正在机化的血栓中。在髂总静脉横跨髂内静脉起始处放置了覆膜支架。正电子发射断层扫描-计算机断层扫描证实存在纵隔和腹膜后淋巴结病变，给予辅助卡铂和紫杉醇化疗。
