Morphologically moderately differentiated adenocarcinoma, intestinal type - I would first think about secondary involvement from colorectal direct extension or metastasis. Primary bladder adenocarcinoma can either be urachal type or intestinal type are pretty rare; urachal type often mucinous or signet ring cell type and located in the dome. Unfortunately IHC stains are often not helpful.
