This includes pancreatic ductal lesions observed in 4 patients, including numerous branch-duct intraductal papillary mucinous neoplasms in 3 patients. Biliary lesions were observed in 1 patient, with a large choledochal cyst also involving the left biliary branch. Finally, multiple inflammatory\/telangiectatic hepatic adenomas were observed in 2 patients, including 1 with proven somatic GNAS mutation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>We describe the first observation of syndromic intraductal papillary mucinous neoplasms and the new association between MAS and pancreatic neoplasms, namely intraductal papillary mucinous neoplasms of the pancreas but also rare hepatobiliary neoplasms including liver adenomas and choledochal cysts. These findings strongly suggest that somatic activating GNAS mutations, possibly through cAMP pathway disorders, are involved in the tumorigenesis of hepatobiliary and pancreatic tissues originating from the foregut endoderm and have led us to use a routine screening by dedicated magnetic resonance imaging including both pancreatobiliary and liver sequences in patients with MAS.<\/jats:p>\n
