Bone tumors Bone tumors are classified into: Primary bone tumors Secondary bone tumors ( Metastasis) Most are classified according to the normal cell of origin and apparent pattern of differentiation

Osteochondroma Morphology Osteochondromas are mushroom shaped and range in size from 1 to 20 cm. The outer layer of the head of the osteochondroma is composed of benign hyaline cartilage varying in thickness Newly formed bone forms the inner portion of the head and stalk, with the stalk cortex merging with the cortex of the host bone.

Osteochondroma (exostosis) Microscopic The cap is benign hyaline cartilage, resembling disorganized growth plate undergoing endochondral ossification. Newly formed bone forms the inner portion of the head and stalk

Chondrosarcoma Microscopic These tumors are composed of lobules of cartilage with anaplastic chondrocytes in the lacunae and with focal enchondral ossification and calcification.

Giant Cell Tumor This is a neoplasm that contains large numbers of osteoclast like giant cells admixed with mononuclear cells. These tumors are slightly more common in females.
