A rare mesenchymal phosphaturic tumor caused severe bone disease in a 51-year-old man. Treatment and surgery offered temporary relief, but the tumor recurred, highlighting the need for ongoing monitoring.

Area of Science:

  • Endocrinology
  • Oncology
  • Orthopedics

Background:

  • Hypophosphatemic osteomalacia can cause significant bone pain and fractures.
  • Mesenchymal tumors can present with complex and varied clinical manifestations.

Observation:

  • A 51-year-old male developed severe hypophosphatemic osteomalacia, motor impairment, and rib fractures over six years.
  • Initial treatment with 1,25-dihydroxycholecalciferol, phosphorus, and calcium led to symptom improvement and normalized biochemical parameters.
  • A highly vascularized mesenchymal phosphaturic tumor of hemangiopericytoma type was identified in the right femur.

Findings:

  • Surgical removal of the tumor provided temporary symptom relief.
  • Recurrence of bone pain necessitated resumption of medical treatment.

  • Tumor regrowth in the right femoral condyle was detected via imaging two years post-surgery.

    • Implications:

    • Mesenchymal phosphaturic tumors require vigilant monitoring due to potential for recurrence.
    • Multidisciplinary management is crucial for patients with rare bone-affecting tumors.
    • Early detection and intervention strategies for tumor recurrence remain critical.
