Abstract

Squamous odontogenic tumour (SOT) is a rare, benign but locally infiltrative epithelial odontogenic tumor arising from remnants cell rests of Serres, Malassez or gingival epithelium. It exhibits very little tendency for aggressive clinical behavior and practically no recurrences have been reported following curettage or conservative surgical removal. Clinically, SOTs presents as a slow growing, intrabony lesion with very few clinical signs and symptoms. Radiographically, they show a well‑demarcated unilocular, triangular radiolucency between the roots of adjacent teeth with hypodense areas and hot spot in the focal lesional area in computed tomography and scintigraphy respectively. Histopathologically, they usually present as islands of benign squamous epithelium in mature connective tissue stroma without the evidence of peripheral columnar cells, palisading nuclei, or stellate reticulum and is characterized by squamous metaplasia of the epithelial cells. Here, we report a rare case of SOT on the left side of the maxilla in a 45 year old male with distinctive computerized tomography and radionuclide imaging features.
