Chondrosarcoma Mimicking Periapical Lesion

Abstract

A 48-year-old patient with leukoderma, showed a discrete radiolucent area in the region of the inferior central incisors, on a routine radiographic examination. There was no symptomatology, no bone cortical ablation, but a positive dental vitality test; a clinical, radiographic follow-up was suggested. The patient did not return, but consulted other professionals who, with the increase of the lesion, performed endodontic treatment of the lower incisors; however, the lesion continued to progress. Another professional performed surgery, curettage, and a bone graft placement. The lesion was highly increased thereafter, which immediately indicated an incisional biopsy that confirmed the diagnosis of a chondrosarcoma. The patient was referred to A. C. Camargo Hospital, and tumor resection was performed with a vascularized graft of the fibula. A protocol was established with adjuvant chemotherapy, but the patient had an allergic reaction and is currently under clinical follow-up, with excellent general health status.
