Peripheral Squamous Odontogenic Tumor: A Rare Case Report

Squamous odontogenic tumor is a benign, locally infiltrative, intraosseous tumor composed of well-differentiated squamous epithelium in the background of fibrous stroma. It was first described in 1975 by Pullon et al and is thought to arise from the rests of Malassez in the periodontal ligament or in the cases of peripheral squamous odontogenic tumor, from gingival surface epithelium and remnants of dental lamina. Squamous odontogenic tumors have shown very little tendency for aggressive clinical behaviour and virtually no recurrences have been reported following curettage and peripheral ostectomy. In addition, only one intra-osseous case has been reported as being associated with a malignant variant. There are two reports of peripheral presentations. We present a case in a 17 year old female patient who presented with a peripheral swelling in the chin region, which was excised and diagnosed as peripheral squamous odontogenic tumor.
