Abstract
A 64‐year‐old man developed hepatic angiosarcoma, and combined hepatocellular and cholangiocar‐cinoma, 36 years after Thorotrast administration. The patient presented with a large mass in the right upper quadrant. His serum α‐fetoprotein increased from 800 ng/ml to 51.2 μg/ml, and liver biopsy disclosed hepatocellular carcinoma. At autopsy, the liver had two different malignant neoplasms; angiosarcoma and combined hepatocellular and cholangiocarcinoma. Metastases of angiosarcoma to both lungs and of cholangiocarcinoma to periaortic lymph nodes were also seen. Interestingly, some neoplastic cells of angiosarcoma exhibited globular hyaline inclusions, which were Periodic‐Acid‐Schiff reaction positive and diastase‐resistant.
