Primary leiomyosarcoma of bone: a report on three patients

Abstract

Primary leiomyosarcoma of bone is a rare aggressive tumor that occurs mainly in older people. It resembles other malignancies clinically and radiologically, and differential diagnosis is based on histopathology, including immunohistochemistry. If leiomyosarcoma is found in bone, the possibility that it is a metastasis from a distant tumor should be investigated. The treatment is surgical excision with wide margins. Here we present three patients who had primary leiomyosarcoma of radius, ilium, and femur, respectively, and who were treated surgically.
