Summary

Lipoma arborescens, a rare synovial condition, can cause chronic joint swelling in children. This case report details successful treatment with intra-articular osmic acid, avoiding surgery.

Area of Science:

  • Orthopedics
  • Radiology
  • Pediatric Rheumatology

Background:

  • Lipoma arborescens is a rare, benign lipomatous proliferation of the synovial membrane.
  • It typically presents as chronic, painless synovial effusion, often affecting a single joint.
  • The etiology remains unknown, necessitating inclusion in the differential diagnosis of chronic childhood monoarticular disease.

Observation:

  • Magnetic resonance imaging (MRI) is a highly effective diagnostic tool for lipoma arborescens.
  • This report describes the fourth pediatric case of lipoma arborescens.
  • The patient was a 13-year-old boy with knee effusion.

Findings:

  • The study highlights intra-articular osmic acid as an alternative treatment for lipoma arborescens.
  • This approach was chosen over surgical synovectomy, which is often recommended but inconvenient.

  • Successful treatment was achieved using intra-articular osmic acid injection.

    • Implications:

    • Intra-articular osmic acid may offer a less invasive treatment option for lipoma arborescens.
    • This case expands the therapeutic strategies for this rare pediatric joint condition.
    • Further research into non-surgical treatments for lipoma arborescens is warranted.
