Osteosarcoma Arising from Iliac Bone Lesions of Hereditary Multiple Osteochondromas: A Case Report.

ABSTRACT:

Introduction

Osteochondromas are benign tumors that arise primarily in the metaphyseal region of long bones. The malignant transformation rate is estimated to be less than 1% and 1-3% in solitary and multiple osteochondromas, respectively. Transformation to osteosarcoma is very rare. Little information is available on treatment or outcome. A rare case of osteosarcoma arising from hereditary multiple osteochondromas of the right iliac bone is reported.
