title: Signet-ring cell carcinoma of the urinary bladder associated with transitional cell carcinoma of the right ureter.
abstract: We report on a case of a 72-year-old male with vesical signet-ring cell carcinoma containing a transitional cell carcinoma (TCC) component. It was associated with pure TCC of the right ureter. No other microscopic changes were found in the bladder. The pathogenesis of this signet-ring cell carcinoma is described.
