BACKGROUND Oncogenic osteomalacia caused by phosphaturic mesenchymal tumors is very difficult to detect.We report a case of tumor-induced osteomalacia caused by a phosphaturic mesenchymal tumor of the left femur in a middle-aged woman after medical imaging and biopsy.CASE SUMMARY A 57-year-old woman presented with progressive bone pain for five years.She was diagnosed with hypophosphatemic osteomalacia,as her laboratory data showed low serum phosphorus and low serum calcium.Her knee joint radiography revealed an osteolytic lesion of the left femur.A computed tomography scan showed mixed density shadows in the left femur.Magnetic resonance imaging of the left femur showed the presence of an oval area with a hypointense signal in T1-weighted magnetic resonance imaging(MRI)and highlow mixed signal in T2-weighted MRI.Biopsy samples revealed the presence of short spindle cells,vascularization,and characteristics of phosphaturic mesenchymal tumors.Tumor resection was performed,and the clinical presentations and laboratory abnormalities were reversed.CONCLUSION Diagnosis of oncogenic osteomalacia is difficult due to the varieties and localization of source tumors and absence of pathognomonic biomedical signs.Our case highlights the importance of a combination of medical imaging and biopsy in the diagnosis of oncogenic osteomalacia caused by a phosphaturic mesenchymal tumor. 展开更多

Oncogenic osteomalacia (OOM) is an uncommon metabolic and bone disease caused by fibroblast growth factor 23 (FGF23), a phosphaturic factor produced by phosphaturic mesenchymal tumors (mixed connective tissue variant, PMTMCTV) characterized by phosphate leakage from kidneys and subsequent hypophosphatemia. In this paper, we present the case of a patient, 42-year-old woman affected by left side limp and pain involving lumbar spine, pelvis and hip joints, referred to the Rheumatology Department of our Hospital for the treatment of a suspected sero-negative spondilo-arthritis. During hospitalization patient began an immuno-suppressive therapy with TNF-alpha inhibitors associated with Pamidornate, Indometacin, Esomeprazole and vitamin D3. Nevertheless pain did not decrease and a new examination found a worst hypophosphatemia (1 mg/dl) with normal Ca and PTH’s plasma values. During the same check-up a painful bulge on the anterior part of the right knee was observed and the Magnetic Resonance Imaging scan revealed an ovular solid lesion in the soft tissue closed to the upper part of the patella. Histological analysis identified the lesion as a PMTMCTV. After surgical removal patient got complete recovery. We will discuss about diagnostic evaluation, differential diagnosis and treatment. 展开更多
