Abstract

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide1). Extrahepatic metastasis of HCC is now increasing due to prolonged survival. Most extrahepatic HCC occurs in patients with advanced stages. The lung, abdominal lymph nodes, and bone are common sites of extrahepatic metastasis. However, the parathyroid gland has not been reported as a metastatic focus. We report the first case of parathyroid metastasis as the first single metastasis site of HCC and microscopic tumor-to-tumor metastasis to a parathyroid adenoma.
