ABSTRACT
Chondroblastoma is a rare benign tumor of cartilage tissue accounting for less than 1% of all bone tumors. The epiphysis of long bones is the typical localization, often extending to the metaphysis. Metaphyseal, metaphysodiaphyseal or pure diaphyseal forms are exceptional. We report a case in a 15-year-old boy who presented a metaphyso-diaphyseal chondroblastoma of the distal portion of the left femur. The inaugural signs were pain and limited joint motion. We discuss the anatomic aspects and the clinical course of this rare tumor and present current knowledge of the histogenesis.
