Chondroblastoma of bone

Abstract

Chondroblastoma is a rare benign neoplasm of cartilaginous origin. It appears as a round or oval translucent area with a thin sclerotic rim situated most often in the epiphysis of a long bone, and occurs mainly in the 12-20 age group. It has an excellent prognosis and the radiological features should suggest the correct diagnosis. Ten cases have been reviewed in this paper. The clinical, pathological as well as the radiological features and the differential diagnosis of this entity are discussed. It is hoped that this will help in its earlier diagnosis.
