Multiple cemental lesions in the jaw bones of a patient with Gardner's syndrome.

Unusual multiple lesions of jaws in a middle-aged woman with all classic manifestations of Gardner's syndrome are reported. Clinical examination revealed a diffuse swelling of the mandible and maxilla with bone-like hardness and numerous radiopaque lesions scattered throughout both mandible and maxilla. Impaction of the molar teeth was revealed by roentgenographic examination. Histopathologically, the multiple jaw lesions consisted of trabecular proliferation of hard-tissue which more closely resembled cementum than immature bone or osteoid. It was found to be united with the cementum of tooth-roots through obliteration of the periodontal ligament. The present lesions do not fit into any of the distinct entities of cemental lesions described.
