The appearance of pulmonary metastasis more than 15 years after primary treatment for breast cancer is rare. We herein report the case of a breast cancer patient with solitary pulmonary metastasis, after an 18-year disease-free period, treated with resection. A 66-year-old Japanese woman was found to exhibit an abnormal shadow on a chest X-ray. She had undergone a left mastectomy for breast cancer 18 years previously. The nodule was suspected to be either metastatic or primary lung cancer, and thus thoracoscopic surgery was performed. The histologic diagnosis was metastasis from breast cancer. Pulmonary resection in breast cancer recurrence is an important diagnostic tool that allows for a differential diagnosis with primary lung cancer. The clinical implication of surgery for a solitary pulmonary metastasis from breast cancer is discussed in this report.
乳腺癌初次治疗15年以上出现肺转移的情况较为罕见。我们在此报告一例乳腺癌患者，在经历18年无病期后出现孤立性肺转移，接受了手术切除治疗。一名66岁的日本女性在胸部X光检查中发现异常阴影。她18年前因乳腺癌接受了左乳房切除术。该结节被怀疑为转移性或原发性肺癌，因此进行了胸腔镜手术。组织学诊断为乳腺癌转移。乳腺癌复发时的肺切除是一种重要的诊断工具，有助于与原发性肺癌进行鉴别诊断。本报告讨论了乳腺癌孤立性肺转移手术的临床意义。
