Case. A 74-year-old man who underwent central bisegmentectomy of the liver as radical treatment for hepatocellular carcinoma (HCC). Even one year after surgery, right pleural effusion was noted on a chest computed tomography scan. Two pleural aspiration procedures failed reveal any significant findings. Subsequently, a tumor shadow was identified in the right lung field with accumulation of contrast on ^<18>F-fluorodeoxy glucose positron emission tomography. One month later, nodules newly appeared on the right pleura. Therefore, we suspected a malignant tumor on the pleura, and performed an operation for diagnostic purposes. Thoracoscopy revealed some hemorrhagic tumors on the chest wall, in addition to a lung tumor. A few chest wall tumors were resected, and the histopathological findings revealed metastatic HCC. Conclusion. Pleural metastasis from HCC is very rare, and few cases have been reported. We report a case of pleural metastases of HCC diagnosed by thoracoscopy.
