The concept of odontogenic keratocyst was introduced by Philipsen in 1956 and described some of its clinical, radiological and microscopic features. This cyst has a thin wall characterized by keratinizing epithelium.<BR>A rare case of odontogenic keratocyst which extended into the contralateral site of maxilla is reported.<BR>A 25 year old woman who complained of right cheek swelling for approximately 10 years, was referred to our hospital September, 1984. Radiological examination revealed a large unilocular radiolucent area in the right maxilla. CT scan revealed a soft mass from the left incisor area to the right molar area suggesting ameloblastoma formation. On the ninth of October, 1984, the lesion was totally enucleated. There was no relationship to any tooth. Histological findings show that the lining epithelium of cyst wall is stratified squamous with parakeratosis and the connective tissue contains islands of epithelium and separated small cysts.<BR>A diagnosis of odontogenic keratocyst was made.<BR>The patient showed no evidence of recurrence of the cyst for 55 months postoperatively.
