title: Solitary, thin-walled cavitary lung metastasis of osteogenic sarcoma.
abstract: Three years after removal of a femoral osteosarcoma, a solitary, thin-walled cavitary lesion (diameter 1 cm) appeared in the lung of a young man. When the lesion enlarged, it was resected. Histology showed sarcoma metastasis with central necrosis and involving a peripheral bronchus. Cavitary metastasis can occasionally result from drainage of necrotizing tumor cells via a peripheral bronchus.
