Type	Description	Location	Incidence	Special things to remember
Endochondroma	Cartilaginous neoplasm in intermedullary bone	Distal extremities (hands and feet)	no special age
Osteoblastoma	Similar to osteoid osteoma (interlacing traveculae of woven bone surrounded by OB but larger	vertebral column	None
Osteoid osteoma	Interlacing traveulae of woven bone surrounded by osteoblasts (proliferation of osteoid and fibrous tissue)	Near end of diaphysis of the femur or tibia	Males under <25
Osteoma	Dense bone maturation (new piece of bone grows on another piece	Skull/facial bones; often protrudes into paranasal sinus	Males of any age
Osteosarcoma (name predisposing factors)	osteoid and bone-producing neoplasm; Codman's triangle, sunburst pattern, increase ALP	Distal femur, metaphysis of long bones, proximal tibial region (knee)	Males 10-20	Predisposing factors: Paget's, bone infarcts, radiation, familial retinoblastoma; early hematogenous spread to liver, lungs, brain
Ewing's sarcoma	Anaplastic "small blue cell" tumor. Onion skin appearance in bone.	Diaphysis oflong bones, pelvis, scapula, ribs	Males < 15	translocation 11;22;responsive to chemo but aggressive with early mets; in early stages may look like acute osteomyelitis
Chondrosarcoma	cartilaginous tumor. Expansile glistening mass within the medullary cavity	pelvis, spine, scapula, humerus, tibia, femur	Males 30-60	May have come from an osteochondroma
Osteochondroma (aka ___)	Exostosis. Cartilage-capped projection from under periosteum	Long metaphysis: distal femer, proximal tibia (knee)	Male <25 years old	Most common benign tumor; rarerly turns into a chondrosarcoma
Giant cell tumor (aka _____)	osteoclastoma. locally aggressive tumor with spindle-shaped cells with multi-nucleated gian cells; soap bubbles, double bubble appearance on X-ray	Epiphyses of long bones (knee is common)	Females 20-40
