Abstract: . . .  found to be accompanied by a point mutation in exon 3 of the b- catenin gene [1]. However, the histological features, in particular the tubulopapillary pattern, the cytology and immunohistochemical data (such as positivity for cyto- keratins and negativity for neuron-specific enolase and vimentin) were not in accordance with such a diagnosis [17]. The tubulopapillary and microcystic pattern of the carcinoma partially resembled the cystic variant of acinar cell carcinoma . This rare tumor affects men more frequently than women [14], usually reaches great di- mensions and can be encapsulated [15, 25]. It contains macrocysts and microcysts with a cuboidal or cylindrical epithelial cell lining. The tumor cells express pancreatic enzymes, such as . . .
