Duodenal adenocarcinoma: a rare cause of intestinal obstruction in young adult

Abstract

Duodenal adenocarcinoma is rare cancer that accounts for less than 1% of all gastrointestinal cancers. The causative factors include increased intake of bread, pasta, sugar and red meat, alcohol, coffee, tobacco and reduced intake of fruits and vegetables. It can arise from duodenal polyps seen in familial adenomatous polyposis (FAP) and Gardner syndrome, or can be associated with celiac disease. They mainly occur in second part of the duodenum, followed by third and fourth. Usually it is seen in middle or elderly age person. In young age, it is associated with polyposis syndromes or with any inflammatory diseases affecting small bowel. But without such syndromes or diseases, it is rare in young age. We are reporting a case of 22 years old male who presented to us with history of recurrent abdominal pain. After evaluation it was diagnosed as adenocarcinoma arising from junction of third and fourth part of duodenum without any genetic syndromes or inflammatory disease.
