Oncogenic Osteomalacia

摘要

Oncogenic osteomalacia is a rare metabolic bone disease characterized by phosphate leak from the kidney and hypophos-phatemia. This is caused by a phosphaturic factor produced by certain tumors. Removal of these tumors can completely cure this condition, We report the case of a patient who was crippled with oncogenic osteomalacia. Extensive study revealed a tumor in the right leg, and the removal of this tumor resulted in complete recovery of the osteomalacia. The tumor was identified as a heman-giopericytoma. The diagnostic evaluation, differential diagnosis, and treatment are discussed.
