What is chondrosarcoma?
Chondrosarcoma is a cancer composed of cells derived from transformed cells that produce cartilage, according to Wikipedia.
The most common locations for chondrosarcoma tumors are the pelvis and shoulder, along with the superior metaphyseal and diaphyseal regions of the arms and legs. It affects rarely the base of the skull.
According to Wikipedia, there is a precise classification of chondrosarcoma based on ICD-O codes.
These subtypes are derived from, and reflect:
(a) the topographical location of the tumor;
(b) the histological characteristics of the cancerous cartilage cells;
(c) the makeup of the surrounding matrix material associated with the tumor.
Below is the list of the classification:
- ICD-O 9220: Chondrosarcoma NOS (“Not Otherwise Specified”)
- ICD-O 9221: Juxtacortical chondrosarcoma
- ICD-O 9231: Myxoid chondrosarcoma
- ICD-O 9240: Mesenchymal chondrosarcoma
- ICD-O 9242: Clear cell chondrosarcoma
- ICD-O 9243: Dedifferentiated chondrosarcoma
