Figure 3. Hematoxylin & eosin-stained histological sections. (A) Magnification ×40. (B) Magnification ×200. (C) Magnification ×40. (D) Magnification ×200. The intestinal phenotype is intracholecystic papillary neoplasm (ICPN). Morphologically, the ICPN has complex tubulo-papillary epithelial growth with pseudostratified nuclei and basophilic cytoplasm. Mitotic activity is scarce and essentially on the basal side of the epithelium.
