[Simultaneous hepatic cholangiocarcinoma and bone fibrosarcoma 45 years after ingestion of Thorotrast]. / Cholangiocarcinome hépatique et fibrosarcome osseux synchrones 45 ans après injection de Thorotrast.

ABSTRACT

This case of a 63 year old man reports the simultaneous development of hepatic cholangiocarcinoma and fibrosarcoma of the sacrum 45 years after the systemic injection of Thorotrast. The characteristic radiologic aspect was an important criteria for diagnosis. Biopsies have confirmed the histology of both tumors. We describe the way to thorotrastosis diagnosis and characteristic malignant tumors, especially cholangiocarcinoma, induced by Thorotrast.
