Chondrosarcoma is a rare flat bone neoplasm. Herein, we present the clinicopathological and immunohistochemical findings of a case affecting the periodontum. A 16-year-old girl presented a painless reddish mass in the lower anterior gingiva. Radiographs showed bone affected by vertical and horizontal loss and enlargement of periodontal space. The histopathological features showed atypical cartilage arranged in lobules compatible with chondrosarcoma. Immunohistochemistry showed that tumor cells were immunoreactive for the anti-vimentin and S-100 antibodies. Moreover, no tumor cells had been immunostained by anti-p53. Treatment consisted of chemotherapy, followed by radical surgery and postsurgery treatment with an association of radio and chemotherapy. After one year, no signs of recurrence have been observed.
