AB  - We present the case of a 78-year-old male who presented
to clinic for follow-up of a papillary transitional cell
carcinoma of the urinary bladder. Notably, the patient
also had a history of colorectal resection for an
adenocarcinoma. The follow-up appointment revealed
left hydronephrosis with evidence of a distal ureteric
stricture. Cytology and biopsy from the ureter
subsequently disclosed the presence of malignant cells
that were originally thought to be of urothelial origin.
Upon surgical resection the lesion was found to be an
adenocarcinoma, morphologically consistent with a
metastasis from the patient’s primary colonic
adenocarcinoma. This case illustrates a diagnostically
challenging situation, with metastatic colonic carcinoma
to the ureter occurring in a patient with two previously
documented malignancies.
