Treatment of Chondrosarcoma as Atypical Cartilaginous Tumour in the Appendicular Skeleton
This protocol applies to chondrosarcoma presenting as an atypical cartilaginous tumour (ACT) at an appendicular skeleton location. The WHO classification places these lesions in a distinct category, with management that differs meaningfully from axial disease.
Clinical Scenario
The WHO classifies these lesions as atypical cartilaginous tumours when located in the appendicular skeleton — distinct from grade 1 chondrosarcoma of the axial skeleton (scapula, pelvis, skull). At extremity sites, ACTs may initially be managed by observation; the decision to intervene is driven by clinical course.
Approach (Partial Overview)
When progression or symptoms occur, a surgical approach targeting local control is employed. The specific technique and the use of adjuvants to augment that control are detailed in the full structured protocol.

The WHO classifies these as atypical cartilaginous tumours in the appendicular skeleton, and grade 1 chondrosarcoma in the axial skeleton (including scapula, pelvis and skull).
In the extremity ACTs can be managed by observation initially.
If there is progression or symptoms, complete curettage with or without surgical adjuvants (e.g. high-speed burr, cryotherapy) has a high chance of local control.
