Phosphaturic mesenchymal tumor of nose: a case report

Abstract Background: To report a case of phosphaturic mesenchymal tumour of nose highlighting the diagnostic challenges involved. Case presentation : A 50 years old male who had history of multiple lower limb fractures presented with epistaxis and a vascular mass in left nasal cavity that enhanced on contrast-enhanced computed tomography (CECT), and MRI. The patient had raised serum phosphate and PTH levels. The tumour was excised endoscopically and the patient recovered completely. Conclusion :Malignant Phosphaturic mesenchymal tumors (PMTs), although rare, may behave aggressively, recur and metastasize. They are difficult to diagnose and should be kept in differential diagnosis of nasal tumours who present with osteomalacia.
