Tumeurs hépatiques malignes primitives en dehors du carcinome hépatocellulaire

Abstract

Malignant primary tumours other than hepatocellular carcinoma are rare. They represent 2% to 3% of the gastrointestinal tract tumours. Unlike hepatocellular carcinoma, they develop most of the time in a non cirrhotic liver. These tumours may derive from the hepatocyte, cholangiocyte, mesenchymatous cells, or endocrine cells. Despite the fact that clinical and imaging features may suggest the nature of the tumour, the final diagnosis is based on the histopathologic examination of a liver biopsy or a surgical fragment.
