title: [Primary malignant tumor of the 4th duodenal segment at the angle of Treitz. Report of a case].
abstract: A case of 34-years old woman with adenocarcinoma of the IVth duodenal segment extended to the angle of Treitz, treated with duodenojejunal segmentary resection, is described. Clinical features and diagnostic strategies are reported. Personal observation compared with Literature confirms the difficulty of an early diagnosis. The most appropriate surgical techniques for the treatment of these particularly and uncommon neoplasms often discovered in advanced stage are discussed. The better prognosis of these adenocarcinomas compared with those of the proximal duodenum (Ist and IInd segments) can be supported by embryological differences currently to be investigated.
