Phosphaturic mesenchymal tumor of the nasal cavity: Clinicopathologic correlation is essential for diagnosis

We present a case of a 66-year-old female who presented with osteomalacia-related symptoms and was found to have a nasal cavity mass. Histopathologic examination was suggestive of PMT but certain characteristic features were lacking, requiring confirmation of the diagnosis by chromogenic in situ hybridization (CISH) assay for FGF23 mRNA. The patient's symptoms and laboratory abnormalities resolved upon resection of the tumor.
