Purpose: Chondroblastoma is a rare benign bone tumor which occurs most frequently at epiphysis of long bones. This study analyzed the difference between patients with chondroblastoma either on their epiphysis or apophysis. Materials and Methods: We reviewed 19 patients with chondroblastoma who visited our hospital from August 1987 to August 2005. The mean follow up period was five years. Fifteen patients were male and 4 patients were female. The mean age of the patients was 17.6 years. The treatment consisted of either curettage alone, curettage with bone graft or curettage with cementation. We retrospectively compared the difference between one chondroblastoma originating from the epiphysis and the other chondroblastoma originating from the apophysis in terms of age predilection, duration of symptoms, size of tumor, status of the physis, presence of pathologic fracture, recurrence rate and accompanying aneurismal bone cyst. Results: Among the 19 patients, 11 patients had chondroblastoma at the epiphysis, and 8 at the apophysis. Distal femur was the most common site for epiphysis lesions while the greater trochanter was the most common site for lesions arising at the apophysis. The mean age was 14.2 years in the epiphysis group and 22.3 years in the apophysis group. Chondroblastoma occurred after closure of the physis in 3 out of 11 cases in the epiphysis group and in all 8 cases in the apophysis group showing a statistical significance between the groups in terms of status of the physis at onset. Size of the lesion was bigger in the apophysis group with statistical significance. Conclusion: Chondroblastoma is known to occur frequently at the epiphysis of long bones, but our study shows that in patients over 20 years old it occurs more frequently at the apophysis which needs to be considered when making the proper diagnosis. There was a significant difference between the two groups in terms of the age of occurrence, status of physis and size of tumor while there was none in terms of the duration of symptoms, presence of pathologic fracture, recurrence rate and presence of accompanying aneurismal bone cyst.
