Abstract
- Chondroblastoma is a rare primary bone tumor and that of sacrum was reported only 4 cases in the literatures. We report the case of 16 year old female with chondroblastoma of sacrum. The lesion was treated by partial excision of sacrum and coccyx as a block at 2nd sacral segment level. The excised tumor was round lobulated mass with diameter of 6 cm, and was consisited by yellowish cartilagenous tissue with scattered focus of calcification. Histological structure showed the proliferation of chondroblasts in chondroid ground substance with scattered multinucleasted giant cells. The ground substance showed the areas of calcification. During 22 months of follow up period, neither evidence of local recurrence nor metastasis could be boserved.
