A male patient in his 70s, who had undergone an abdominoperineal (A1) resection for rectal cancer 20 years prior, presented with hemoptysis. Imaging studies revealed distant lung recurrence, with no evidence of local recurrence. Biopsy revealed an adenocarcinoma, possibly of rectal origin. Immunohistochemical markers were suggestive of rectal cancer metastasis. However, carcinoembryonic antigen (CEA) levels were normal, and colonoscopy did not reveal any metachronous lesions. Curative left upper lobe resection was performed via posterolateral thoracotomy. The patient's recovery was uneventful.
一名70多岁的男性患者，20年前因直肠癌接受了腹会阴联合切除术（A1），现出现咯血症状。影像学检查显示远处肺部复发，无局部复发迹象。活检显示为腺癌，可能起源于直肠。免疫组化标记提示为直肠癌转移。然而，癌胚抗原（CEA）水平正常，结肠镜检查未发现任何异时性病变。通过后外侧开胸术进行了根治性左上叶切除术。患者恢复顺利。
