Area of Science:

  • Orthopedics
  • Pediatric Oncology
  • Pathology

Background:

  • Intracortical osteosarcoma is a rare bone tumor variant.
  • Oncogenic osteomalacia (rickets) is linked to specific tumors.

Observation:

  • A 9-year-old boy presented with oncogenic rickets and tibial intracortical osteosarcoma.
  • Tumor resection led to rickets resolution and normalized lab values (except alkaline phosphatase).

Findings:

  • Histology revealed an osteosarcoma with an osteoblastic pattern and calcified spherules.
  • Differential diagnosis included benign osteoblastic tumors; infiltrating pattern confirmed osteosarcoma.
  • The intracortical osteosarcoma was identified as the cause of rickets.

Implications:
