Lymphatic spread of colon cancer usually occurs via mesenteric vessels (superior and inferior mesenteric vessels), but inguinal lymph node (LN) metastasis from colon cancer is extremely rare with only few reported cases in the literature. A case of a 35-year-old female patient with a history of sigmoid cancer underwent sigmoidectomy and left salpingo-oopherectomy in 2016 and received adjuvant chemotherapy then presented in 2023 with metastatic left inguinal LNs and underwent left inguinal LN dissection. We reported a rare case of isolated metachronous inguinal lymph node metastasis from colon cancer with a round ligament route of spread as the hypothesized mechanism. Surgical resection with inguinal LN dissection is the preferred treatment option for isolated inguinal lymph node metastasis from colon cancer followed by adjuvant chemotherapy, yet long term follow-up data is needed to support this strategy.
结肠癌的淋巴转移通常通过肠系膜血管（肠系膜上、下血管）发生，但结肠癌发生腹股沟淋巴结转移极为罕见，文献中仅有少数病例报道。一名35岁的女性患者，有乙状结肠癌病史，于2016年接受了乙状结肠切除术和左侧输卵管卵巢切除术，并接受了辅助化疗，2023年出现左侧腹股沟淋巴结转移，随后接受了左侧腹股沟淋巴结清扫术。我们报告了一例罕见的结肠癌异时性孤立性腹股沟淋巴结转移病例，推测其转移途径为圆韧带途径。对于结肠癌孤立性腹股沟淋巴结转移，首选的治疗方案是行腹股沟淋巴结清扫术并联合辅助化疗，但仍需要长期随访数据来支持这一策略。
