#Pseudostratified (crowded appearing) columnar (or cigar-shaped) nuclei - '''key feature'''. | |||
#*Vaguely resembles [[colonic adenocarcinoma]]. | |||
#Compatible architecture: | |||
#*Papillary. | |||
#*Cribriform. | |||
#*Single gland (large glands). | |||
#*Endometrioid - vaguely looks like [[endometrioid endometrial carcinoma]] (with back-to-back glands). | |||
#>= 50% of tumour.<ref name=pmid21383610/> | |||
#*If ductal component <50%, it is a conventional (acinar) adenocarcinoma with a ductal component. | |||
