Intestinal malrotation (IM), a rare congenital anomaly disrupting typical embryonic rotation around the superior mesenteric artery, is exceptionally uncommon in adults, with its link to colon cancer being even rarer. This article presents a case of colonic cancer in conjunction with IM in a 63-year-old male. Image studies and intraoperative findings show signs of IM. Open resection was performed due to concerns about vascular anomalies and abnormal lymphatic drainage. The case underscores the rarity of colon cancer in a malrotated gut, highlighting the necessity of preoperative identification for precise surgical planning and emphasizing the importance of careful dissection to prevent inadvertent vascular injury.
肠旋转不良（IM）是一种罕见的先天性异常，会破坏围绕肠系膜上动脉的典型胚胎旋转，在成年人中极为罕见，其与结肠癌的关联更是罕见。本文介绍了一名63岁男性患有结肠癌合并IM的病例。影像学检查和术中发现显示有IM的迹象。由于担心血管异常和异常淋巴引流，进行了开放切除术。该病例强调了旋转不良肠道中结肠癌的罕见性，突出了术前识别以进行精确手术规划的必要性，并强调了仔细解剖以防止意外血管损伤的重要性。
