비출혈로 진단된 전이성 간세포암종 1예

A rare case of metastatic hepatocellular carcinoma (HCC) of the nasal cavity in a 54-year-old man is reported along with the findings at biopsy. Radiographic examination revealed masses in the liver and lung metastases. Histologically, proliferation of tumor cells with resemblance to HCC was observed. Extrahepatic metastasis of HCC is not infrequently found during the later stage. Hepatocellular carcinoma usually metastasizes to lung, breast, lymph node, GI tract, bone, kindey, and adrenal gland. However, metastasis to the nasal cavity and paranasal sinuses has been seldom reported in our knowledge. Epistaxis in patients with metastasis to the nasal cavity can be difficult to control by conventional method. Epistaxis was successfully treated by transcatheter arterial embolization.
