Urinary bladder adenocarcinoma diagnosed by urine cytology

Report of two cases

Abstract

Two cases of urachal carcinoma of the urinary bladder, which were diagnosed from findings of cystoscopy and urine cytology, are described. Case 1 was a 78-year-old female, case 2 a 61-year-old female. Macrohematuria was the only complaint in both patients. In both cases cytoscopy revealed a tumor in the apical region of the urinary bladder, and urine cytology showed well-or moderately differentiated adenocarcinoma cells with mucin production. While the urinary sediment included adenocarcinoma cells in case 2, in case 1 adenocarcinoma cells were disclosed in a mucinous jellylike substance floating after centrifugation but not in the urinary sediment.
