Abstract
Tumor-induced osteomalacia (TIO), also known as oncogenic osteomalacia, is very rare, with about 1000 reported cases globally. Removing most TIO culprit tumors requires the evaluation and intervention of orthopedic doctors. However, orthopedic doctors often have a poor understanding of the optical treatment of TIO due to its rarity. In addition, most TIO patients lack specific clinical manifestations. Also, the clinical localization and qualitative diagnosis of TIO are difficult and thus can easily be misdiagnosed and mistreated. Furthermore, the true incidence rate of TIO may be underestimated. Although many breakthroughs have been made in exploring the pathogenesis, clinical diagnosis, and treatment of TIO, rational and standardized orthopedic surgical treatment experience summary and sorting for TIO patients are lacking. In this article, the recent experience and progress in the field of orthopedic surgical treatment for TIO globally have been summarized, providing a theoretical basis and new clinical practice guidance for the rational treatment of TIO patients.

Abstract
To report a case of osteomalacia induced by a mesenchymal tumour in the head and neck region, in view of its rarity and classical late diagnosis. To review the literature on the usage of fluorodeoxyglucose-positron emission tomography-computed tomography (FDG PET-CT) and octreotide scanning in the localisation of the culprit tumour. An elderly male presented with a 7-year history of chronic muscle pain and weakness, to the extent of functional disability. FDG PET-CT was done which showed uptake in the region of the right anterior ethmoids. Endoscopic excision of the mass was done. However, the patient did not improve significantly. Subsequently, a DOTA-1-NaI3-octreotide (DOTANOC) scan was done which revealed a tumour in the region of the right medial rectus, excision of which was done. This time, the patient improved clinically and biochemically. The histopathology was phosphaturic mesenchymal tumour. A steady but definitive symptomatic improvement was noted in the postoperative period along with reversal of the deranged biochemical parameters, confirming the diagnosis of oncogenic osteomalacia. Octreotide-based PET-CT seems to be the most sensitive imaging modality in localising the tumours that cause oncogenic osteomalacia. However, FDG-based PET-CT still would be a good choice in centres where SSTR-based imaging facilities are not available.

Abstract
Phosphaturic mesenchymal tumors (PMTs) are neoplasms associated with tumor-induced osteomalacia. Patients typically present with pathologic fractures in the setting of chronic hypophosphatemic hyperphosphaturic osteomalacia, as well as gradual muscle weakness, bone pain, and difficulty walking. Because of their rarity and nonspecific symptomatology, phosphaturic mesenchymal tumors often go undiagnosed for years. Even when discovered on imaging, the tumors can be diagnostically challenging for radiologists. Phosphaturic mesenchymal tumors often tend to be small and can be located nearly anywhere in the body, and, therefore, can mimic many other tumors. This case highlights the imaging and pathologic markers of a phosphaturic mesenchymal tumor, often found in a patient with tumor-induced osteomalacia.

Abstract
The oncogenic hypophosphatemic osteomalacia is a very incapacitating disease and the mortality rate, mainly due to metabolic disorder, depends on the early diagnosis, since the surgery is curative. The major difficulty is to consider this kind of disease in patients with complex clinical presentation. Moreover, medical centers have to provide a good diagnostic infrastructure because these tumors, in most cases, are small and do not have an obvious site. This case report is about a man with a rapid loss of strength and muscle mass, which had his diagnosis in a late, culminating in significant deformities and organic dysfunctions with clinical repercussions. However, the fast diagnosis with appropriate tests determined the stop point of the evolution of disease and marked the beginning of metabolic recovery. This case reinforces the global problem health care infrastructure and the access to diagnostic equipment, demonstrating the impact on the patient’s health of our service.

Abstract
Tumor-induced osteomalacia (TIO) is an acquired form of hypophosphatemia. Tumor resection leads to cure. We investigated the clinical characteristics of TIO, diagnostic methods, and course after tumor resection in Beijing, China, and compared them with 269 previous published reports of TIO. A total of 94 patients with adult-onset hypophosphatemic osteomalacia were seen over a 6-year period (January, 2004 to May, 2010) in Peking Union Medical College Hospital. After physical examination (PE), all patients underwent technetium-99m octreotide scintigraphy ((99) Tc(m) -OCT). Tumors were removed after localization. The results demonstrated that 46 of 94 hypophosphatemic osteomalacia patients had high uptake in (99) Tc(m) -OCT imaging. Forty of them underwent tumor resection with the TIO diagnosis established in 37 patients. In 2 patients, the tumor was discovered on PE but not by (99) Tc(m) -OCT. The gender distribution was equal (M/F = 19/20). Average age was 42 ± 14 years. In 35 patients (90%), the serum phosphorus concentration returned to normal in 5.5 ± 3.0 days after tumor resection. Most of the tumors (85%) were classified as phosphaturic mesenchymal tumor (PMT) or mixed connective tissue variant (PMTMCT). Recurrence of disease was suggested in 3 patients (9%). When combined with the 269 cases reported in the literature, the mean age and sex distribution were similar. The tumors were of bone (40%) and soft tissue (55%) origins, with 42% of the tumors being found in the lower extremities. In summary, TIO is an important cause of adult-onset hypophosphatemia in China. (99) Tc(m) -OCT imaging successfully localized the tumor in the overwhelming majority of patients. Successful removal of tumors leads to cure in most cases, but recurrence should be sought by long-term follow-up.

Abstract
We report the case of a patient with severe muscular and articular tenderness that caused almost complete immobility. This subject had severe hypophosphatemia due to hyperphosphaturia. Fibroblast growth factor 23 (FGF-23) was abnormally high and the diagnostic of tumor-induced osteomalacia was made. Despite multiple tests, the tumor was not localized. In this report, we discuss different possible investigations to localize the tumor. Lastly, we review the potential therapy available when tumor is not found and can thus not be excised.

Abstract
Tumor-induced osteomalacia (TIO) is a rare and fascinating paraneoplastic syndrome in which patients present with bone pain, fractures, and muscle weakness. The cause is high blood levels of the recently identified phosphate and vitamin D-regulating hormone, fibroblast growth factor 23 (FGF23). In TIO, FGF23 is secreted by mesenchymal tumors that are usually benign, but are typically very small and difficult to locate. FGF23 acts primarily at the renal tubule and impairs phosphate reabsorption and 1α-hydroxylation of 25-hydroxyvitamin D, leading to hypophosphatemia and low levels of 1,25-dihydroxy vitamin D. A step-wise approach utilizing functional imaging (F-18 fluorodeoxyglucose positron emission tomography and octreotide scintigraphy) followed by anatomical imaging (computed tomography and/or magnetic resonance imaging), and, if needed, selective venous sampling with measurement of FGF23 is usually successful in locating the tumors. For tumors that cannot be located, medical treatment with phosphate supplements and active vitamin D (calcitriol or alphacalcidiol) is usually successful; however, the medical regimen can be cumbersome and associated with complications. This review summarizes the current understanding of the pathophysiology of the disease and provides guidance in evaluating and treating these patients. Novel imaging modalities and medical treatments, which hold promise for the future, are also reviewed.

Abstract
The authors describe a case of oncogenic osteomalacia due to a mesenchymal phosphaturic tumour in the maxillary sinus. This is a paraneoplastic syndrome in which a tumour produces a peptide hormone-like substance (phosphatonin) that causes a urinary loss of phosphates resulting in a debilitating systemic condition. In this case, the patient experienced muscle stiffness, reduction of muscle tone, loss of weight and pathological fractures. Clinical and radiological examination revealed a tumour in the right maxillary sinus; all other results were negative. The diagnosis following pathology examination was mesenchymal phosphaturic tumour with a haemangiopericytoma-like vascular pattern. Different histological types of mesenchymal tumours can be associated with paraneoplastic syndrome, but their localization in the paranasal sinuses is rare. The correct diagnosis allows the appropriate therapeutic approach, which can lead to an almost immediate resolution of the clinical situation after surgical removal of the neoplasm as in the present case. Oncogenic osteomalacia is rare, particularly in the maxillofacial region, and only a few cases have been reported.
