[TYPICAL TYPE CYSTITIS GLANDULARIS PRESENTING URINARY RETENTION IN A YOUNG MAN: ADJUVANT THERAPY USING ORAL CYCLOOXYGENASE-2 INHIBITOR: A CASE REPORT].

A 31-year-old man was referred to our hospital with urinary retention. Cystoscopy revealed multiple edematous papillary tumors on the bladder trigone and neck, which were removed by transurethral resection. The pathological diagnosis was typical type cystitis glandularis. This relapsed six months after surgery and transurethral resection was repeated. Because immunohistochemical findings revealed positive epithelial cyclooxygenase-2 (COX-2) signals, we prescribed an oral COX-2 inhibitor. The tumor revealed shrinkage for six months after medication.
