Background
A few reports have described the effectiveness of resection for recurrent cholangiocarcinoma. However, none have described resection of synchronous pulmonary metastasis from distal cholangiocarcinoma. We report the first case, to the best of our knowledge, of a slow-growing synchronous pulmonary metastasis from distal cholangiocarcinoma resected 3.5 years after the initial surgery.
Case presentation
A 67-year-old Japanese man with a diagnosis of distal cholangiocarcinoma was referred to our hospital. Thickening of the distal bile duct and an air-space pattern in the upper lobe of the left lung were detected by preoperative computed tomography. He underwent pancreaticoduodenectomy for the distal cholangiocarcinoma. Follow-up chest computed tomography demonstrated that the air-space pattern in the left lung had gradually enlarged. Thoracoscopic left S6 segmentectomy with lymph node dissection was performed 3.5 years after the initial surgery. Histopathology of the resected specimen revealed a solitary metastasis from distal cholangiocarcinoma with lepidic growth. We diagnosed the patient with a solitary synchronous pulmonary metastasis from distal cholangiocarcinoma.
Conclusions
Surgical resection might offer better long-term survival to patients with synchronous pulmonary metastasis from distant cholangiocarcinoma than nonsurgical treatments. Pulmonary metastasis from distal cholangiocarcinoma may exhibit a lepidic pattern. Therefore, because of the possibility of synchronous pulmonary metastasis, pulmonary resection should be considered for patients with lepidic lesions who have been diagnosed with distal cholangiocarcinoma.
