Carcinoma in situ of the urinary bladder in bladder washing cytology.
Doo Hyun Chung, In Ae Park, Eui Keun Ham
ABSTRACT
The diagnosis of carcinoma in situ of urinary bladder is difficult in that the symptoms and cystoscopic findings are nonspecific. The cytology of urine could be helpful for diagnosis of carcinoma in situ of urinary bladder. We present a case of bladder washing cytology of carcinoma in situ. A 54 year old man presented with dysuria for 1 year. Cystoscopic findings revealed multifocal reddish trabeculated lesions. The bladder washing cytology revealed rather uniform tumor cells which were singly scattered or forming syncytium in the clean background. The nuclei were round to oval with inconspicious nucleoli. The cystoscopic biopsy revealed typical histologic features of carcinoma in situ of urinary bladder.
Key Words: carcinoma in situ; Urinary bladder; Washing cytology
