Multiple keratocysts of the jaws are habitual in the nevoid basal cell carcinoma syndrome (Gorlin and Goltz. Syndrome). The authors report 3 cases of multiple keratocysts in a 28 year-old woman and in two men respectively ages of 27 and 21 years. In the third case some anomalies in which calcification of the falx cerebri were noted and suggested the Gorlin's syndrome. The limits of this syndrome with multiple keratocysts of the jaws are discussed.
