Gingival squamous cell carcinoma mimicking a dentoalveolar abscess: report of a case.

Because of its close proximity to teeth and periodontium, gingival squamous cell carcinoma (SCC) can sometimes mimic tooth-related benign inflammatory conditions, resulting in misdiagnosis. In this study we report a case of gingival SCC that mimicked a dentoalveolar abscess of endodontic origin in its early presentation. The course and treatment of this case is discussed and a brief review of the literature is presented. Because many patients with gingival SCC visit dentists as their initial professional contact, it is hoped that the case can serve as a reminder for dentists to keep the possibility of carcinoma in mind when examining intraoral lesions.
