Papillary Thyroid Cancer in a Patient with MUTYH-Associated Polyposis (MAP)

key information

source: Familial cancer

year: 2010

authors: Pervaiz M A, Eppolito A, Schmidt K


We describe a patient with MUTYH-associated polyposis diagnosed with colon cancer at 33 years of age, as well as gastric polyps at a later age. She was also diagnosed with papillary thyroid cancer at age 35. MUTYH-associated polyposis is an autosomal recessively inherited disease which has clinical overlap with Familial adenomatous polyposis and its attenuated form, in that it is associated with risk of colon cancer at a young age. Extra-intestinal cancers have also been reported in patients with MUTYH-associated polyposis; however the tumor spectrum is still evolving. National Comprehensive Cancer Network guidelines recommend screening for colon, duodenal and gastric polyps in individuals with MUTYH-associated polyposis. Screening for extra-intestinal cancers i.e. thyroid cancer is presently not part of these recommendations. These will likely continue to evolve as the MUTYH-associated polyposis tumor spectrum is better understood as a result of future case reports and research.
