BACKGROUND Tumor-induced osteomalacia is an uncommon paraneoplastic syndrome caused by Fibroblast growth factor-23-secreting tumors. It is characterized by phosphaturia, hypophosphatemia, and a high plasma level of alkaline phosphatase. CASE PRESENTATION We report a young patient with psoriasis who had suffered from bone pain and muscle weakness for more than 6.5 years. He was finally diagnos...

Rickets and osteomalacia are associated with hypophosphatemia in several disease states, including X-linked hypophosphatemic rickets, autosomal-dominant hypophosphatemic rickets, and tumor-induced osteomalacia. Recent advances in the understanding of these diseases include discovery of mutations in the genes encoding human phosphate-regulating gene with homologies to endopeptidases on the X chr...

Oncogenic osteomalacia (OO) is an uncommon but treatable cause of osteomalacia related to tumor production of FGF23, usually caused by benign mesenchymal neoplasms. Paranasal sinus glomangiomas are a rare cause of OO, with only one previously reported case. Here we describe a second case (first reported in English) of paranasal sinus glomangioma-induced osteomalacia in a 42-year-old man. He pre...
