AbstractAbstract PDF
Tumor-induced osteomalacia (TIO), a paraneoplastic disease, is characterized by hypophosphatemia, and caused by renal phosphate wasting inappropriately, normal or decreased 1, 25(OH)2D3 production, and defective calcification of cartilage and bone. Because the removal of the responsible tumor normalizes phosphate metabolism, unidentified humoral phosphaturic factors (phosphatonin) are believed to be responsible for this syndrome. These factors include fibroblast growth factor (FGF)-23, secreted frizzled-related protein-4 and matrix extracellular phosphoglycoprotein. However, no case of TIO producing FGF-23 has been clearly reported in Korea. Herein, a case of TIO producing FGF-23 in a 45-year-old woman is reported. The patient presented with a large tumor on her buttock, with severe bone and muscle pain. A histological examination of the tumor revealed a mixed connective tissue tumor, consisting of deposition of calcified materials and surrounding primitive spindle cells, with prominent vascularity. Whether FGF-23 is a secreted factor, as well as its levels of expression in tumors were investigated. An immunohistochemical study showed the tumor cells to be FGF-23 positive. Furthermore, the levels of serum FGF-23 were extremely high and an RT-PCR analysis, using total RNA from the tumor, revealed the abundant expression of FGF-23 mRNA. After removal of the tumor, all the biochemical and hormonal abnormalities disappeared, with marked symptomatic improvement.
