Resumen de Squamous Odontogenic Tumor:: Diagnosis and Management
Kamram Haghighat, John R. Kalmar, Angelo Mariotti
The squamous odontogenic tumor (SOT) is a rare, benign, locally infiltrative neoplasm of the jaws that appears to originate from the rests of Malassez. It has been confused with other pathologic entities such as ameloblastomas, carcinomas, and fibromas and clinically may resemble localized periodontal disease. The tumor is often asymptomatic, although it can present with symptoms of pain and tooth mobility. A characteristic radiographic appearance is that of a triangular- shaped or semi-circular lucency associated with the roots of erupted teeth. Histologically, the tumor is characterized by the formation of variably sized nests and cords of uniform, benign-appearing, squamous epithelium with occasional vacuolization and keratinization. Treatment of SOT by conservative surgical excision is normally curative with rare episodes of recurrence reported. Since the clinical presentation of SOT may mimic more common pathologic entities, this case report reinforces the need for careful histologic evaluation of all lesions found in the periodontium.
