Transformation of an idiopathic bone infarct into malignant fibrous histiocytoma in a female. A case report.

Abstract

A case report of malignant degeneration of a long-standing idiopathic bone infarct into malignant fibrous histiocytoma in a female is presented. Most of the previous cases reported were in males. The pathogenesis is still obscure; however, a cause-and-effect relationship may exist. The prognosis is poor. Most patients die within two years after diagnosis.
