a Intestinal-type adenocarcinoma, papillary subtype. The tumor has ample papillary projections, and some glandular and tubular areas. H–E stain ×250. b The cells are usually cylindrical with elongated and pleomorphic hyperchromatic nuclei and nuclear crowding. Several mitotic figures are seen. H–E stain ×400. c Intestinal-type adenocarcinoma, highly differentiated papillary subtype resembling normal intestinal mucosa. H–E stain ×150. d Note the orderly arrangement of cylindrical cells in the papillae with only mild nuclear atypia. Occasional mitotic figures are seen. H–E stain ×400
