Primary osteosarcoma of the liver.
Extraskeletal osteosarcomas are infrequent, and those that arise within parenchymal organs are very rare indeed. This case of a 71-year-old man with a primary osteosarcoma of the liver is the second reported in man. Pathologic findings, including ultrastructural features, at surgery and autopsy are presented. The differential diagnosis is discussed in detail.
