RESUMEN
The carcinoma of the jejunum represents 3-6.5% of gastric intestinal tumors and 33-50% of small intestine carcinomas. The observation of a case of jejunum carcinoma has offered the authors the idea for a critical revision on the subject. After an examination on the diagnostic, anatomopathological, clinical and therapeutic problems, the authors underline the importance of the precocious diagnosis of neoplasia; in fact the jejunum carcinoma is characterized by a hidden and aspecific symptomatology and by dangerous evolution; besides the site is difficult for an organic study with the common methods of investigation. Therefore, in all patients in whom the suspicion of a jejunum pathology exists, it is indispensable to carry out a precise diagnostic iter which is based on radiological endoscopic and tomographic investigation: in fact the small intestine and the jejunum in particular are intestinal tracts that are explored with difficult and therefore at times only an accurate effecting of the radiological study can permit a precocious diagnosis the only valid supposition for the carrying out of a truly radical surgical therapy and for the acquiring of a batter prognosis.
