Bone tumors

Angiosarcoma of bone

BoneMalignant / sarcomaVascular tumours of bone

Epidemiology

A very rare vascular sarcoma of bone, usually in adults, that can be multifocal. Because of its aggressiveness and possible multifocality, it is assessed with staging imaging before surgery is defined.

Basic features

It tends to destroy bone and form a soft-tissue mass, with progressive pain or a pathologic fracture (a break through weakened bone).

Usual treatment

Complete resection with negative margins is the central goal when feasible, because achieving full local control is the main factor linked to a better outcome; radiotherapy and systemic treatment are added depending on the extent of disease or when surgery is not possible.

Outcomes and prognosis

It carries a high risk of metastasis and recurrence and an unfavorable prognosis, related to the extent of disease and to local control.

Warning signs

These signs do not necessarily mean cancer, but they warrant evaluation before operating on or needling a mass.

  • A soft-tissue mass that grows, is larger than 5 cm, or is deep.
  • Persistent, night-time or progressive bone pain, especially if it limits activity.
  • A fracture from minimal trauma, or an aggressive bone lesion on an X-ray.
  • A lump that comes back after previous surgery.
  • Neurological symptoms, rapid swelling, or pain associated with a mass.

This information is general and does not replace a medical evaluation. A musculoskeletal tumor must be interpreted together with imaging, physical examination, biopsy when appropriate and each patient's context.

Specialist evaluation

If you have a mass, a bone lesion or a report suggesting a tumor, book an evaluation.
