Calcifying odontogenic cyst is a relatively rare disease reported first by Gorlin et al.in 1962.<BR>Recently, we encountered a 25-year-old woman with this disease bilaterally in the region of the lower wisdom teeth.<BR>Orthopantomography revealed relatively well-defined, periodontal cyst-like radiolucencies of the size of a thumb ball bilaterally in the region of the lower wisdom teeth. Under local anesthesia with 2% Xylocaine, extraction of the left lower wisdom tooth and excision of the cyst were performed. The lesion on the right side was also managed by extraction of the wisdom tooth and cystectomy. The wounds on both sides were treated with gauze tamponage.<BR>Histopathologically, the cyst walls in both locations were composed of markedly degenerated stratified squamous epithelium containing ghost cells which were partly calcified.<BR>The postoperative course was uneventful without evidence of recurrence.
