SUMMARY Our gastrointestinal tract is colonized by trillions of microbes. There growing recognition that commensal bacteria can promote the development colorectal adenomas and cancer. For example, bacterial plaques are strongly associated with in familial adenomatous polyposis (Science 2018;359:592-597), fusobacterium cancer liver metastasis.(Science 2017;358:1443-1448)

Abstract Parotid gland is a rare site of metastasis from gastrointestinal (GI) tract primary cancer.
