Case 1: A 52-year-old @entity1 receiving regular treatment for @entity1688 due to @entity7960 visited our hospital with the chief complaint of macroscopic @entity811 . He had undergone cystostomy 12 years ago due to @entity1494 . The computed tomography and cystoscopic examination revealed a @entity150 with a few @entity3226 . Transurethral resection of @entity150 (TUR-Bt) was performed after @entity3226 removal in May 2000. The pathological diagnosis showed @entity652 . Case 2: A 54-year-old @entity1 had been treated with @entity150 by TUR-Bt in Nov. 1995. The pathological diagnosis showed @entity1606 , G3, pT2 and intravesical instillation therapy using @entity7312 was performed. The @entity150 had recurred twice and the instillation therapy had been exchanged to BCG since Nov. 1997. A small @entity150 was observed in Jan. 2001, and from the biopsy specimen it was diagnosed as @entity652 . Forty-six cases of urothelial @entity652 including our cases have been reported in Japan. Chronic stimulation such as @entity3226 and @entity281 is thought to induce @entity652 . BCG instillation therapy is believed to be an initiation factors for @entity652 .
