Bladder enteric-type adenocarcinoma is a rare primary malignancy of the urinary bladder, that is predominantly observed in males and accounts for up to 2% of all bladder cancers1. It is characterized by histological and molecular features that closely mimic those of colorectal adenocarcinoma. These include its enteric-type glandular architecture and the frequent expression of intestinal markers such as CDX2 and CK20, as well as the variable CK7 expression2.
