Background:Tumor-induced osteomalacia (TIO), which is also known as oncogenic osteomalacia, is an uncommon paraneoplastic syndrome characterized by a renal phosphate loss causing hypophosphatemia, leading to rickets in children and osteomalacia in adults. It is caused by mesenchymal tumors, which secrete FGF-23 (fibroblast growth factor-23) and rarely other phosphotonins. It can present with a wide range of symptoms and there is often a delay in its diagnosis. Early diagnosis is important and surgical excision can cure the disease in most patients, thus preventing the complications.We report a case of TIO, who was diagnosed at an early stage and underwent curative surgery.
