Chondroblastoma in distal femur: a case report

Chondroblastoma was first described as calcified giant cell tumor by Ewing. Chondroblastoma is a rare primary benign tumor of bone with a relatively high incidence in older children. Ninety percent of patients are between the ages of 5 and 25 years; males predominate with a ratio of 3 to 2. Metastasis of a histologically benign chondroblastoma is rare. The suggested treatment for aggressive chondroblastoma ranges from simple curettage to resection with a margin of surrounding normal tissue and structural reconstruction. In this report, our aim was to present a rare tumor chondroblastoma which was localized in the distal femoral epiphysis.
