Calcified mixed malignant tumor of the liver.

Two adult patients died from mixed hepatic tumors of the liver with metastasis. The outstanding findings in both patients were a long clinical course, roentgenologically identifiable calcification of the tumors, and, in one, hypertrophic osteoarthropathy and spider angiomas. Mixed hepatic tumors are rare in adults, only 14 possible previous cases have come to our attention. The mixed hepatic tumors of adults are morphologically different from the more common mixed hepatoblastomas of infancy and childhood. Calcification in a slow-growing tumor in an adult without cirrhosis may indicate a mixed hepatic tumor.
