Adenocarcinoma consistent with colorectal primary (H&E stain); (C) rectal wall: neoplastic cells are positive for CDX2 immunostaining; (D) bladder wall: positive for malignancy. High-grade urothelial carcinoma. (Pap Stain); (E) bladder wall: positive for malignancy. High-grade urothelial carcinoma.
