Abstract

SERAFINI, Enriqueta M. et al. Tumor-induced osteomalacia: rhinosinusal hemangiopericytoma. Medicina (B. Aires) [online]. 2013, vol.73, n.1, pp.39-42. ISSN 0025-7680.

Tumor-induced osteomalacia is a rare disease of bone metabolism. The characteristic of this disease is an increase in phosphate excretion followed by hypophosphatemia, due to phosphaturic agents produced by different types of tumors. Tumor resection results in complete resolution of clinical, biochemical and radiological abnormalities. We present the case of a 61 year old man with signs, symptoms and laboratory findings consistent with oncogenic osteomalacia due to a rhino-sinusal mesenchymal tumor. The histological diagnosis showed a vascular neoplasm: hemangiopericytoma.

Keywords : Tumor-induced osteomalacia; Hypophosphatemia; Hemangiopericytoma; Oncogenic osteomalacia.
