Colonic metastasis from ovarian cancer is extremely rare, with only seven reported cases. A 77-year-old woman who had previously undergone surgery for ovarian cancer was admitted to a local hospital with anal bleeding. Histopathological analysis confirmed the presence of adenocarcinoma. Colonoscopy revealed a descending colon tumor. The patient was diagnosed with Union for International Cancer Control T3N0M0 descending colon cancer or colon metastasis of the ovarian cancer. Laparoscopic left colectomy was performed; intraoperative frozen section diagnosis confirmed metastasis from ovarian cancer, and the absence of invasion to the serosal surface suggested hematogenous metastasis. This is the first case of colonic metastasis from ovarian cancer that was diagnosed using an intraoperative frozen section and laparoscopically treated.
卵巢癌的结肠转移极为罕见，仅有7例报道。一名77岁曾接受过卵巢癌手术的女性因肛门出血入住当地医院。组织病理学分析证实为腺癌。结肠镜检查发现降结肠肿瘤。该患者被诊断为国际癌症控制联盟T3N0M0期降结肠癌或卵巢癌结肠转移。行腹腔镜左半结肠切除术；术中冰冻切片诊断证实为卵巢癌转移，且未侵犯浆膜表面提示血行转移。这是首例通过术中冰冻切片诊断并经腹腔镜治疗的卵巢癌结肠转移病例。
