8-Year Follow-up of Central Giant Cell Lesion Mimicking Apical Periodontitis

Abstract

IntroductionLesions of nonendodontic origin may mimic apical periodontitis. Central giant cell lesions (CGCLs) are aggressive or nonaggressive benign idiopathic intraosseous lesions of the jaw. This report describes a case of a CGCL in the periapical region of teeth #21–#26 of a 17-year-old female who sought orthodontic care because of a change in the position of tooth #23. MethodsClinical examination revealed mild facial asymmetry caused by increased volume in the mental region and cortical bone expansion but no cortical disruption. A panoramic radiograph showed a well-defined radiolucent osteolytic lesion involving teeth #21–#26. The cortical bone was not affected, and there was no root resorption. Incisional biopsy was performed, and the diagnosis was a CGCL. The lesion was enucleated surgically. CGCLs should be included in the differential diagnosis of jaw lesions that mimic apical periodontitis. ResultsThe patient subsequently underwent orthodontic treatment successfully. ConclusionsThe 8-year clinical and radiographic follow-up confirmed lesion remission, no recurrence, and pulp vitality of all teeth.
