Abstract
Squamous cell carcinoma rarely occurs in the gingiva and may be misdiagnosed as inflammatory lesions that most commonly affect this area. A 51-year-old patient was referred for evaluation of a lesion in the gingiva. The patient was nonsmoker and nondrinker, and he reported local symptomatology for 3 years since the lower left first molar was rehabilitated with porcelain crown. On oral examination an erythematous lesion in the vestibular marginal gingiva of the lower left first molar was observed. In addition, white areas in the lower anterior vestibular gingiva were present. In view of the clinical hypothesis of malignant neoplasia, incisional biopsy was performed, and the histopathologic analysis confirmed the diagnosis of squamous cell carcinoma. The patient was referred to a head and neck surgeon, who performed a surgical removal of the tumor. This report emphasizes that although is uncommon, squamous cell carcinoma of gingiva may occur and may mimic an inflammatory process.
