In benign tumors, the neoplastic bone usually consists of relatively well-formed trabeculae of woven bone, whereas in malignant bone forming tumors (osteosarcoma), it is usually deposited in a coarse lace-like pattern. Lamellar cortical-type neoplastic bone is generally only present in osteoma (and enostosis), however, it can rarely be a component of well-differentiated osteosarcoma. …
