Clinical and radiological findings in Gardner's syndrome: a case report and follow-up study.

Abstract

Gardner's syndrome is characterized by colorectal adenomas, multiple osteomas, especially of the skull, and various soft-tissue tumours. The disease is inherited as an autosomal dominant disorder and all untreated patients will develop colorectal adenocarcinomas. Since the clinical and radiological stigmas in the maxillofacial area, such as exosteal and endosteal osteomas, skin cysts, atypical skin pigmentation and abnormal dental findings or radiopaque lesions can precede the often symptomless adenomas for many years, dentists, maxillofacial surgeons and radiologists should be familiar with the manifestations of this disease. A case is reported to illustrate the dentist's role in the diagnosis of Gardner's syndrome. In a follow-up study of 11 patients with colorectal adenomas, the typical triad of features of Gardner's syndrome was found in eight. In six patients, bony changes were demonstrated by panoramic radiography. It is proposed that radiography of the jaws may serve as a valuable tool for the early detection of carriers of Gardner's syndrome.
