Mesenchymal chondrosarcoma
Mesenchymal chondrosarcomas are a rare chondrosarcoma subtype.
Pathology
They are found in both bone and soft tissues (see: extraskeletal chondrosarcoma).
Histology
Mesenchymal chondrosarcomas are characterised by bimorphic histology:
- densely packed small round blue cells similar to those seen in Ewing's sarcoma
- cells are seen in a perivascular arrangement which is reminiscent of haemangiopericytomas
- malignant cartilaginous tumour

The differential diagnosis for bone tumours is dependent on the age of the patient, with a very different set of differentials for the paediatric patient.
