An 83-year-old man with a calcifying odontogenic cyst (COC) on the mandible is reported. The Japanese literature describing such cases in the elderly is also reviewed<BR>An elderly man complained that his denture did not fit. Roentogenographic examination indicated a large multiple cystic lesion of the mandible, but there were no radiopaque findings. The lesion was extirpated surgically and was pathologically diagnosed as odontogenic keratocyst. Ghost cells and calcified tissues were found in the epithelium of the keratocyst. Daughter cysts were also found.<BR>Our case is the oldest reported patient with COC, but nine cases above 60 years of age, including our case, have been reported in Japan. Four patients were in their 60 s, 3 in thier 70 s and 2 in thier 80s. Four lesions occurred in the maxilla and 6 in the mandible (two lesions were found in one case). Among patients over 70 years of age (5 cases), large cysts were predominant. Therefore, fenestration was performed in 2 cases.
