Vascular leiomyosarcoma, a rare vascular tumor, exceptionally affects children. This case highlights the aggressive nature and poor prognosis of pediatric peripheral vascular leiomyosarcoma despite treatment.

Area of Science:

  • Oncology
  • Vascular Surgery
  • Pediatric Pathology

Background:

  • Vascular leiomyosarcoma originates from smooth muscle cells in vessel walls.
  • Distinguishes between proximal (large vessels) and peripheral (limbs, subcutaneous) types.
  • A rare malignancy with limited pediatric case studies.

Observation:

  • Presents a rare case of a 6-year-old child with congenital peripheral vascular leiomyosarcoma.
  • Immunohistochemistry confirmed tumor markers: vimentin, smooth muscle actin (SMA), and desmin.
  • Despite aggressive treatment including surgery and chemotherapy, the patient's condition worsened.

Findings:

  • Pediatric vascular leiomyosarcoma is exceptionally rare.
  • Tumor cells expressed vimentin, SMA, and desmin.

  • Aggressive disease progression observed despite multimodal therapy.

    • Implications:

    • This case underscores the challenges in managing pediatric vascular leiomyosarcoma.
    • Prognosis is significantly influenced by local recurrence and metastatic potential.
    • Highlights the need for further research into effective pediatric vascular leiomyosarcoma treatments.
