RESUMEN
Liver neoplasms, whether they are benign or malignant, are usually fed by the hepatic artery. We experienced a case of hepatic angiosarcoma supplied by both hepatic artery and portal vein. Since there are currently no specific laboratory tests to diagnose hepatic angiosarcoma, it is important to detect suspect cases from imaging features. This unique hemodynamic property was detected on computed tomography (CT) during hepatic arteriography and CT during hepatic arterioportography. If any imaging examinations indicate the liver tumor to be fed by the portal vein, hepatic angiosarcoma should be suspected.

Sera from 93 patients with connective tissue disease, 36 rheumatoid arthritis, 41 systemic lupus erythematosus, 12 polymyositis/dermatomyositis and 4 systemic sclerosis and sera from 12 patients with liver disease, along with sera of 10 healthy subjects, were tested for antikeratin antibodies using enzyme-linked immunosorbent assay in which the wells were coated with human epidermal keratin. Values above the mean+SD of the 10 healthy subjects were found in 8.3% of rheumatoid arthritis, 29.3% of systemic lupus erythematosus, 33.3% of polymyositis/dermatomyositis, 50% of systemic sclerosis, 16.7% of liver disease patients, and 20% of healthy subjects. The results indicated a character of naturally occurring antibody of antikeratin antibodies in human sera.
