Definition / General
  • Benign cartilaginous tumor
  • Either enchondroma (arise from diaphyseal medullary cavity), subperiosteal/juxtacortical chondroma or soft tissue chondroma
  • Cytofluorometric DNA ploidy analysis may be useful in distinguishing these tumors from chondrosarcomas (Mod Pathol 1999;12:863)
Molecular / Cytogenetics Description
  • 12q13-15 (HMGA2 / HMGI-C) is involved in structural rearrangements (also in other benign mesenchymal tumors, Mod Pathol 2003;16:1132)
