Overview

Enchondroma must be differentiated from low-grade chondrosarcoma, fibrocartilaginous dysplasia, bone islands and bone infarcts. Periosteal chondroma must be differentiated from periosteal chondrosarcoma and periosteal osteosarcoma.

Differential Diagnosis

Enchondroma must be differentiated from the following:[1][2][3][4][5]

  • Low-grade chondrosarcoma
    • When differentiating an enchondroma from a chondrosarcoma, the radiographic image may be equivocal. However, periostitis is not usually seen with an uncomplicated enchondroma.[1]
  • Chondroblastoma
    • Presence of bone marrow edema frequently seen surrounding chondroblastomas is helpful, as it is not a usual feature of chondromyxoid fibromas, giant cell tumors, or enchondromas.[2][3]
  • Fibrocartilaginous dysplasia
    • Fibrous dysplasia is seen with an extensive cartilagenous differentiation that results in a picture that mimics enchondroma.
    • Cellular atypia in the surrounding stroma helps in the differentiation.[4]
  • Bone islands[5]
  • Bone infarcts
    • Differentiating an enchondroma from a bone infarct on plain film may be difficult.
    • An enchondroma usually causes endosteal scalloping while an infarct will not.
    • An infarct usually has a well-defined, sclerotic serpentine border, while an enchondroma does not.[1]

Periosteal chondroma must be differentiated from the following:
