title: Hepatocellular carcinoma presenting as bone metastasis.
abstract: In a consecutive series of 395 patients with pathologically verified hepatocellular carcinoma, 20 patients (5%) had bone metastasis at initial presentation. Of these, 16 were men and four women ranging from 26 to 64 years of age (median, 50 years). The age, sex, hepatitis B surface antigen seropositivity, alpha-fetoprotein level, and frequency of associated cirrhosis were not statistically different from those in patients without initial bone metastasis. Initial presentation was usually the result of spinal lesion with neurologic compression, and chest wall or scalp mass. Metastasis most commonly involved spine and ribs, and occurred as osteolytic lesions or extrapleural mass. Computed tomography proved best for demonstrating an expansile soft tissue mass with bony destruction. Angiography showed hypervascular appearance over the destructive bone area. Treatment results were poor. The follow-up period ranged from 3 weeks to 14 months with a median survival of 5 months. The data suggested that hepatocellular carcinoma be ruled out in patients with osteolytic lesions.
