title: Early detection but delayed appearance of a bladder tumor.
abstract: Herein is described a case of bladder cancer first detected by urinary cytology 20 years before a definite cystoscopic diagnosis could be established. To our knowledge, this represents the longest such interval on record. The case indicates the reliability of Papanicolaou studies of the urine, especially when tumor cells are identified.
