Tumor-Induced Osteomalacia: A Case Report of Rare Disease and Literature review

Background Oncogenic osteomalacia term used for tumor-induced (TIO) is a paraneoplastic syndrome of abnormal phosphate metabolism secondary to ectopic endocrine tumors. The diagnosis often becomes difficult due rarity occurrence and deficient literature. reconstruction following resection has its own technical difficulties, which are addressed in this article. Presentation Case A 39-year-old female presented with pain bilateral lower limbs difficulty mobilizing. patient had unexplained hypophosphatemia was diagnosed tumor (arising ectopically greater trochanter), inducing osteomalacia. She managed successfully excision reconstruction. biochemical parameters improved drastically within 5 days fracture healed 6 weeks' time. Conclusion TIO debilitating disease significant morbidity prolonged onset interval localizing the causative tumor. So thorough clinico-radiological laboratory parameter correlation necessity. rapid followed by complete surgical excision, remains gold standard treatment modality that confers favorable prognosis most patients, strict vigilance recurrence required.
