Gardner Syndrome is a rare inherited condition that is considered part of the familial adenomatous polyposis (FAP) spectrum. It is caused by a pathogenic variant in the APC gene and is characterised by multiple adenomatous polyps in the colon and rectum, along with extracolonic features such as osteomas, dental abnormalities, epidermoid cysts, desmoid tumors, and other benign or malignant growths.
Early diagnosis and regular surveillance are important because adenomatous colorectal polyps associated with APC-related polyposis can gradually develop into colorectal cancer. In classic FAP, colorectal cancer risk becomes extremely high without appropriate preventive management. Timely treatment may involve regular colonoscopy, removal of suitable polyps, upper gastrointestinal surveillance, genetic counselling, and preventive colorectal surgery when indicated. Monitoring can also help identify extracolonic complications such as desmoid tumors, thyroid abnormalities, dental and jaw lesions, and duodenal or gastric polyps at an earlier stage.
Causes
Risk Factors
Colonoscopic Surveillance and Polyp Removal: Regular colonoscopy helps monitor colorectal polyps and remove suitable adenomas. Upper GI endoscopy may also be used to detect and manage selected stomach or duodenal polyps.
Preventive Colorectal Surgery : Colectomy or proctocolectomy may be recommended when polyps become extensive, high-grade dysplasia or cancer develops, or adequate endoscopic surveillance is no longer possible.

Management of Extracolonic Manifestations: Desmoid tumors, osteomas, epidermoid cysts, thyroid abnormalities, and other manifestations may require regular monitoring, medication, endoscopic treatment, or surgery depending on their severity.
Treatment of Colorectal Cancer : If colorectal cancer develops, treatment may involve surgery along with chemotherapy, radiation therapy, targeted therapy, or other systemic treatments depending on the cancer's stage and characteristics.

Genetic Counselling and Long-Term Follow-Up: Genetic counselling and APC testing can help identify affected family members and guide early surveillance. Lifelong follow-up is important to monitor the colon, upper gastrointestinal tract, and other associated manifestations.
