| |
| |-
| |
| | Chondroblastoma||Bone or joint pain in adolescent||Epiphysis of long bones, may cross growth plate||Growth disturbance, arthritis
| |
| |-
| |
| | Enchondroma||Soft tissue mass in hands or feet of adolescent; seen in Ollier Disease or Mafucci Syndrome||Metaphysis of long bones in hands or feet; oval lesion with sclerotic edges and central lucency||Malignant transformation to chondrosarcoma if multiple lesions present
| |
| |-
| |
| | Langerhans cell histiocytosis of bone||Painful swelling of skull in children, typically frontal bone, or long bones||Lytic, punched out lesion||Lesion of skull can be associated with diabetes insipidus or other CNS disease; pathological fracture of long bone
| |
| |-
| |
| | Osteoblastoma||Adolescent male with chronic pain in spine, most often seen in posterior column||Similar to osteoid osteoma but typically > 2cm||May appear like osteoid osteoma on plain film but DOES NOT respond to Aspirin/NSAIDs
| |
| |-
| |
| | Osteochondroma||Adolescent male with painless mass over distal femur||Osseous spur that arises from cortex pointing away from joint||Observation without treatment; small risk of transformation to chondrosarcoma
| |
| |-
| |
| | Osteoid Osteoma||Adolescent male with bone pain over femur; pain worse at night and unrelated to activity||Radiolucent nidus with sclerotic edges most often seen in proximal femur||Nidus produces prostaglandins, Aspirin/NSAIDs can relieve pain; most soft resolve
