Benign Chondroblastoma of Bone: A Case Report

A benign chondroblastoma of bone which involved the proximal end of the right tibia of a 14 year old girl was presented. Clinical symptoms, signs, roentgenographic findings, and bone biopsy led to the diagnosis. The lytic lesion of bone, which was 4cm×3cm×2.5cm in size, was curetted and autogenous bone graft was done. Most of the lesion was composed of a dark bluegray substance, which was either friable or even hemorrhagic, and the other areas were more grayish, gritty and flecked with yellowish calcified material. The postoperative course has been satisfactory, showing no recurrence for a period of 10 months after surgery.
