Multifocal osteosarcoma in a child presented unusually with pancytopenia and widespread lesions. Amplification of the c-myc oncogene may drive aggressive disease progression.

Area of Science:

  • Pediatric Oncology
  • Skeletal Dysplasias
  • Cancer Genetics

Background:

  • Multifocal osteosarcoma is a rare variant of osteosarcoma.
  • Early diagnosis and understanding of its aggressive nature are critical in pediatric cases.

Observation:

  • A 10-year-old boy presented with multifocal osteosarcoma affecting the entire skeleton, pleura, bone marrow, and lungs.
  • Initial presentation included severe anemia, thrombocytopenia, and hypocalcemia.

Findings:

  • Despite aggressive chemotherapy, the patient succumbed to the disease within one month of diagnosis.
  • Cytogenetic analysis revealed multiple chromosomal abnormalities and c-myc oncogene amplification in tumor cells.

Implications:

  • Multifocal osteosarcoma should be considered in pediatric differential diagnoses for pancytopenia and multiple bone lesions.
