Abstract: | Despite the great number of neoplastic entities, which are able to cause this disease, "oncogenous osteomalacia" is hardly known as a paraneoplastic phenomenon. Without removing the not constantly malignant tumor as the underlying cause recovery is not possible. Until now pathogenesis is unknown. Together with a review of the literature a case report is presented, in which a malignant fibrous histiocytoma of soft tissue caused an untreatable osteomalacia. Because of failure of local tumor control prognosis in this case must be considered fatal. |
