Malignant Phosphaturic Mesenchymal Tumor With Lung Metastasis

Key Points

• Lung metastasis occurs in rare malignant phosphaturic mesenchymal tumors, indicating aggressive behavior.
• Clinical presentation is marked by tumor-related bone pain and elevated phosphaturia, suggesting a metabolic impact.
• Histological examination reveals mesenchymal characteristics, correlating with phosphaturic effects.
• Management may require complex surgical interventions; further understanding of biomarker roles in prognosis is needed.
