[Eosinophilic tumors of the duodenum and pancreas. Apropos of a case].

The authors relate about a case of tumorlike eosinophilic infiltration of the duodenum and pancreas. The preoperative workup included the traditional gastroduodenography and arteriography but also more modern investigations as echography and scanography which have not been often employed previously in this pathology. This case shows also how the involvement of the duodenum by the infiltration usually leading to carry out a cephalic duodenopancreatectomy for a benign lesion. The authors recommend conservative management if clinic, duodenographic, echographic and scanographic findings are not associated with the evident signs of carcinoma of the pancreas or of the Vater's region especially in tired patients.
