This study describes two pediatric osteosarcoma cases with lymph node metastases presenting as palpable masses. Early detection and imaging are crucial for managing these challenging bone cancer spread cases.

Area of Science:

  • Oncology
  • Pediatric Oncology
  • Musculoskeletal Oncology

Background:

  • Osteosarcoma is a primary bone cancer predominantly affecting children and young adults.
  • Lymph node metastasis is a significant prognostic factor in osteosarcoma, impacting treatment strategies.
  • Accurate detection and characterization of metastatic disease are critical for effective patient management.

Observation:

  • Two pediatric patients with lower limb osteosarcoma and suspected lymph node metastases were analyzed.
  • Metastases presented as palpable masses in the inguinal and pelvic regions.
  • Imaging modalities including plain radiography, computed tomography (CT), and bone scintigraphy were utilized for diagnosis.

Findings:

  • One inguinal metastasis was detected on initial examination and surgically removed with the primary tumor.

Related Experiment Videos

  • A pelvic metastasis appeared 12 months post-amputation, demonstrating rapid, unresectable growth on CT scans.
  • Osteoblastic osteosarcoma was identified in one of the patients.

    • Implications:

    • This case series highlights the varied presentation and progression of lymph node metastases in pediatric osteosarcoma.
    • The findings underscore the importance of comprehensive imaging surveillance for detecting metastatic disease, even after primary treatment.
    • Understanding metastatic patterns aids in refining treatment protocols and improving outcomes for young osteosarcoma patients.
