Overview

Bone and cartilage tumors may be classified according to the WHO histological classification system into benign and malignant tumors, and categorized into 5 sub-types: cartilage tumors, osteogenic tumors, fibrohistiocytic tumors, notochordal tumors, hematopoietic tumors, and miscellaneous tumors.[1][2] In addition, bone and cartilage tumors may be sub-classified according to tumor location into 4 subtypes: diaphysis, metaphysis, epiphysis, and ungrouped/others.[3]

Classification

Bone and cartilage tumors may be classified by location, origin, and histopahological origin.

  • Tumor location
  • Diaphysis
  • Epiphysis
  • Metaphysis
  • Other/Unclassifed
  • Tumor nature
  • Benign
  • Malignant
  • Origin
  • Primary
  • Secondary ( see "Classification" table, below)
  • Histopathological origin
  • Cartilage tumors
  • Osteogenic tumors
  • Fibrohistiocytic tumors
  • Notochordal tumors
  • Hematopoietic tumors
  • Miscellaneous tumors.


  • The table below summarizes the classification of bone and cartilage tumors according to histopathological origin, tumor location, and tumor nature.[1][2]
Bone or cartilage mass classification
Adapted from ICD-10/WHO (9180–9269)[3]
Osteogenic tumors: bone-forming tumors Cartilage tumors: cartilage-forming tumors Fibrogenic or fibrohistiocytic tumors Cystic tumors Others ( hematopoietic, notochordal, and neuroectodermal)
Histological Type
  • Osteoid osteoma
  • Osteoblastoma
  • Osteoma
  • Osteosarcoma
  • Osteochondroma
  • Chondroblastoma
  • Enchondroma

  • Non-ossifying fibroma
  • Unicameral bone cyst
  • Aneurysmal bone cyst
  • Giant cell tumor
  • Adamantimoma
  • Eosinophilic granuloma
  • Ewing sarcoma
  • Metastases
Epiphysis Diaphysis Metaphysis
Tumor Location
  • Chondroblastoma
