Abstract

A case of primary adenocarcinoma of urinary bladder associated with cystitis glandularis in a forty-year-old man is presented. Urothelial mucosa near the neoplasm was diffusely manifested with an advanced degree of metaplastic change of intestinal type, which transformed into a form of borderline lesion or adenomatous growth and apparently into adenocarcinoma. The nature and diagnostic significance of such an intermediate lesion in the urinary bladder were discussed.
