Background
Gardner syndrome, a variant of familial adenomatous polyposis (FAP),[1] is an autosomal dominant disease characterized by GI polyps, multiple osteomas, and skin and soft tissue tumors. Cutaneous findings[2] of Gardner syndrome include epidermoid cysts, desmoid tumors, and other benign tumors. Polyps have a 100% risk of undergoing malignant transformation; consequently, early identification of Gardner syndrome is critical.[3]
Pathophysiology
Gardner syndrome is genetically linked to band 5q21, the adenomatous polyposis coli locus.[4] FAP and Gardner syndrome are believed to be variants of the same condition. The wider spectrum of abnormalities found in Gardner syndrome may represent variable penetrance of a common genetic mutation.
Epidemiology
Frequency
United States
One person per million population is diagnosed with Gardner syndrome. The incidence of FAP is 1 case per 8000 people. The most common cutaneous finding in patients with Gardner syndrome is epidermoid cysts (50-65%).
Mortality/Morbidity
Unless surgical transection is performed, GI polyps may progress to malignancy in almost 100% of Gardner syndrome patients (rates vary from 58-100% in studies).
Age
Although colonic polyps begin to form in puberty, the average age at Gardner syndrome diagnosis is 22 years. Osteoma formation precedes polyposis. Usually, progression to malignancy is observed in patients aged 30-50 years. The average age by which malignancy is diagnosed is 39.2 years.
