Question

Quizplus · Accepted Answer

An osteosarcoma is a malignant bone-forming tumor. It is aggressive and most often found in bone marrow; it has a moth-eaten pattern of bone destruction. A fibrosarcoma begins in the bone marrow and infiltrates the trabeculae. It tends to be a solitary tumor that affects the metaphyseal region of the femur or tibia. A chondrosarcoma spreads by seeding.
