Chondroblastoma is a benign, chondroid-producing neoplasm composed of chondroblasts. It accounts for less than 1% of all bone tumors and usually arises in the epiphyses or apophysis of skeletally immature patients. Jaffe et al. proposed the term "chondroblastoma," noting the immature chondroid cells and poorly formed matrix. These neoplasms usually occur in the long bones and are important, considering both benign and malignant etiologies in the differential diagnosis. The proximal humerus is the most common site of involvement, followed by the distal femur and proximal femur. Chondroblastomas require surgical treatment. In general, chondroblastoma has a good prognosis, and patients often experience full resolution after surgical treatment.
