[A Case of Hepatocellular Carcinoma Relapse in the Lungs 17 Years after Liver Resection].

A 77-year-old man underwent a right hemihepatectomy for hepatocellular carcinoma in 2002. The patient remained alive without recurrence for 17 years after surgery. In September 2019, he was diagnosed with a tumor in the lower lobe of the right lung by follow-up CT. A partial right lung resection was performed in February 2020. Histological and immunohistochemical staining confirmed the recurrence of a previous hepatocellular carcinoma. Late lung cancer recurrence after radical hepatectomy is rare. Here, we report a case of hepatocellular carcinoma relapse in the lungs 17 years after liver resection.
