This study presents three rare cases of angiosarcoma associated with bone infarcts. The findings suggest a potentially poor prognosis, similar to other sarcomas linked to bone infarcts, and hint at a possible causal link.

Area of Science:

  • Orthopedic Oncology
  • Vascular Pathology
  • Skeletal Radiology

Background:

  • Bone infarcts are rarely associated with sarcomas, typically osteogenic sarcoma, fibrosarcoma, or malignant fibrous histiocytoma.
  • The association between bone infarcts and angiosarcoma is exceptionally rare.

Observation:

  • Three male patients, mean age 43, presented with high-grade angiosarcoma arising from a bone infarct in the femur.
  • Radiography, CT, and MRI were used for diagnosis, with pathological fracture noted in two cases.
  • Open biopsy confirmed angiosarcoma in all three cases.

Findings:

  • Treatment varied: amputation, segmental resection with adjuvant therapy, and intramedullary rodding.
  • Survival outcomes were mixed, with one patient alive at 3 years post-treatment and another deceased at 6 months.

  • The overall survival rate appears unfavorable, comparable to other sarcomas linked to bone infarcts.
  • Implications:

    • This series adds to the limited cases of angiosarcoma associated with bone infarcts, establishing its rarity.
    • The findings suggest a potential cause-and-effect relationship between bone infarcts and the development of bone sarcomas.
    • Further research is needed to understand the pathogenesis and improve prognostic outcomes for this rare condition.
