title: [Primary adenocarcinoma of jejunum with obscure gastrointestinal bleeding].
abstract: A case of primary small bowel adenocarcinoma is reported because of the rarity of this malignancy. Interestingly, the location of the tumour was in jejunum, instead of the most common site in duodenum. The clinical presentation was anemia, with positive fecal blood test, under antiaggregant platelet treatment for coronary heart disease, initially related to endoscopic evidence of erosive gastroduodenitis. The exacerbation of gastrointestinal bleeding during proton pump inhibitors therapy and the recurrence of abdominal pain caused careful investigation. The source of the obscure gastrointestinal bleeding had been achieved by wireless capsule endoscopy, because of not diagnostic findings of conventional upper endoscopy control, colonscopy, double contrast enteroclysis and selective arteriography. The primary definitive therapy was a radical resection of the jejunal neoplastic loop, important prognostic factor.
