[Ascending choledochal papillomatosis (author's transl)].

A case of benign ascending choledochal papillomatosis is reported. The pathogenetic, diagnostic and therapeutic points of view and the prognosis of this disease are discussed in the light of cases so far communicated in the literature. Although, histologically, the choledochal papillomatosis is a benign tumor, its clinical course corresponds to that of a malignant growth. That being so, a radical removal of the tumor is guaranteed exclusively by duodenopancreatectomy.
