Metastatic bone tumor is a very important disease clinically. Sometimes we have been at a loss for diagnosis and treatment of metastatic bone tumor. In this time, we have investigated metastatic bone tumor in our hospital for the past seven years. We have got 49 cases. In thses cases, liver was the most frequent as primary lesion. The purpose of this paper is to report the clinical course of these cases which visited our department of orthopaedic surgery in spite of affected with hepatoma. In the metastatic bone tumor with hepatoma, the metastasis to the lung was very rare, but metastasis to the bone was more frequent at the first visiting. The location of the metastasis was much more in shoulder girdle than upper or lower extremities and spine. The sites of the metastasis were in rib, clavicle, sternum and scapula. On the first visiting to our department, there were no symptom of hepatoma. The vertebral venous plexus will be concerned with bone metastasis of hepatoma in some references. In the case of bone metastasis with unknown origin, it should be examined for primary liver as same as pancreas or kidney.
