Familial adenomatous polyposis (FAP): Case report from Lima, Peru

Abstract

Familial adenomatous polyposis (FAP) is an autosomal dominant mutation causing loss of function in the tumor suppressor gene APC. The aim of this report is to present a case of FAP. It involves a patient with presence of polyps in the stomach, duodenum, colon, and pancreatic cysts, and a history of symptoms of nausea, vomiting,
and abdominal pain. This case is reported because it is a relatively rare disease worldwide and is not considered
common in any country, including Peru. However, since FAP is a hereditary condition, its prevalence may vary depending on the population and the genetic background of individuals in that specific region.
