Summary
This case study details a rare multifocal bony hemangioendothelioma in a 67-year-old man. Successful treatment involved surgery, cement filling, and radiotherapy, with no recurrence observed.
Area of Science:
- Oncology
- Orthopedic Surgery
- Radiology
Background:
- Hemangioendothelioma is a rare bone tumor, accounting for 0.5% of primary malignant bone tumors.
- Typically found in long bones and tarsal bones, presenting diagnostic challenges due to its rarity.
Observation:
- A 67-year-old male presented with left knee pain 11 years after ankle surgery for a tumor.
- Imaging revealed multiple bone defects with cortical lysis in the femur, tibia, and talus.
- Pathology confirmed grade I multifocal bony hemangioendothelioma.
Findings:
- The patient's laboratory findings were normal.
- Computed tomography showed lytic lesions without cortical or soft tissue involvement.
- Histological examination confirmed multifocal bony hemangioendothelioma.
Implications:
- Multifocal bony hemangioendothelioma requires tailored therapeutic management due to histological variations.
- Surgical curettage, cement filling, and postoperative radiotherapy proved successful in this case.
- Long-term follow-up is crucial for monitoring potential recurrence of this rare tumor.
