A Case of Solitary Mediastinal Metastasis of Hepatocellular Carcinoma

Background. Solitary mediastinal metastasis of hepatocellular carcinoma (HCC) is very rare. Case. A 51-year-old man was admitted to our hospital for transcatheter arterial chemoembolization (TACE) to multiple HCCs. His CT scan revealed a solitary anterior mediastinal mass on the right hemidiaphragm. We suspected noninvasive thymoma and performed right hemithymectomy under thoracoscopic surgery. The pathological examination on immunohistochemical staining including Hep Par 1 revealed metastasis of HCC. As a solitary paraaortic lymph node swelling was found near the right renal artery 3 months after this resection, we speculated the mediastinal mass had also been a solitary metastasis to the right anterior diaphragmatic lymph node. He is receiving UFT orally and is alive with disease 18 months after surgery. The solitary mediastinal metastasis of HCC is very rare and we found only 11 reports including this case. Five cases who had good local control were alive for more than 1 year. Thoracoscopic surgery for a solitary mediastinal metastasis may yield a favorable prognosis. Conclusion. Tumor resection under thoracoscopic surgery for a solitary mediastinal metastasis of HCC is simple and safe, and may yield favorable outcomes for such cases.
