[Parosteal chondrosarcoma. A report of two cases]

Area of Science:

• Orthopedic Oncology
• Soft Tissue Tumors

Background:

• Parosteal chondrosarcoma is a rare bone tumor that arises on the surface of a bone.
• It is distinct from juxta-cortical chondrosarcoma, presenting as an extra-periosteal tumor without bone attachment.

Observation:

• This tumor primarily develops in the soft tissues.
• It is characterized by its extra-periosteal nature and lack of direct bone attachment.

Findings:

• Literature review indicates a high frequency of recurrence following local excision of parosteal chondrosarcoma.
• Amputation is frequently required to manage this condition effectively.

Implications:

• The findings suggest that conservative surgical approaches may be insufficient for parosteal chondrosarcoma.
• Amputation should be considered as a primary treatment option to prevent recurrence and ensure adequate tumor removal.
