Tumor-Induced Osteomalacia as a Result of a Phosphaturic Mesenchymal Tumor: Detecting Rare Origin

Phosphaturic mesenchymal tumor (PMT) is strongly related to tumor-induced osteomalacia (TIO) which brings diverse skeletal events, such as bony deformities, gait disturbance, and multiple bone fractures. Overexpressed fibroblast growth factor 23 by the induces hypophosphatemia leading oncogenic osteomalacia, a rare paraneoplastic syndrome. PMT occurring in oral maxillofacial regions extremely rare, this case highlights need understand mechanisms local lesions can affect systemic conditions, importance of combination physical examinations, laboratory investigations, radiologic investigations for decisive diagnosis.
