[edit] Discussion of Chondromyxoid fibroma

  • Chondromyxoid fibroma is a rare, benign, cartilaginous neoplasm.
  • It typically manifests as an eccentric, lucent, metaphyseal lesion oriented along the long axis of a bone.
  • When the lesion grows large, a "cortical bite" without periostitis is characteristic.
  • Chondromyxoid fibroma affects long bones in 80% of cases, 55% of which involve the tibia and femur.
  • In the tibia, proximal metaphyseal involvement is most common.

  • Patient age is typically 20–30 years.
  • Male-to-female ratio is usually 1:1.

  • At histologic analysis, variable proportions of fibrous, chondroid, and myxoid tissue are seen.

  • Surgical resection is performed for cure. Metastases do not occur, as this is a benign process.

  • Lucent, well-defined, slightly expansile lesion with endosteal sclerosis; it is oriented along the long axis of the host bone.
