Abstract

A 63-year-old man underwent transurethral resection of a bladder tumor to treat superficial bladder cancer in 1995. Histological examination showed urothelial carcinoma, G2>G3 with carcinoma in situ (CIS) at the bladder neck. He underwent postoperative intravesical bacillus Calmette-Guerin (BCG) therapy. In June, 2003, he complained of rubor of his external urethral meatus and visited our clinic. Biopsies at the external urethral meatus and the fossa navicularis of the urethra showed CIS. Radiological examinations, cystourethroscopy and multiple biopsies from other sites of urothelium, including bladder and urethral mucosa, did not reveal any other malignancies. Thereafter, partial penectomy and bilateral inguinal lymphadenectomy were performed. Histological examinations showed CIS at the urethral mucosa of the fossa navicularis and the skin of the glans penis. Postoperative urine cytologies were negative.
