Carcinogenesis encompasses processes that lead to increased mutation rates, enhanced cellular division (tumour growth), and invasive growth. Colorectal cancer (CRC) carcinogenesis in carriers of pathogenic APC (path_APC) and pathogenic mismatch repair gene (path_MMR) variants is initiated by a second hit affecting the corresponding wild-type allele. In path_APC carriers, second hits result in the development of multiple adenomas, with CRC typically emerging after an additional 20 years.

Gardner syndrome is characterized by multiple intestinal polyps and extraintestinal lesions. We describe FDG PET/CT findings of the extraintestinal lesions in a patient with Gardner syndrome. FDG PET/CT showed 2 hypermetabolic desmoid tumors in the abdominal wall, sclerotic areas with multifocal activity in the maxilla and mandible, multiple osteomas in the bilateral parietal, left frontal, sphenoid and ethmoid bones, an impacted tooth in the right maxilla, and bone islands in the T2 and T5 vertebral bodies.

Background: Familial adenomatous polyposis (FAP) is an autosomal dominant colorectal tumour syndrome characterised by the formation of multiple adenomatous polyps throughout the colon. It is important to understand the extracolonic phenotype that characterizes FAP. Most previous case reports of patients with both FAP and intellectual disability (ID) have described deletions in all or part of chromosome 5q, including the APC locus.
