[A case of cystitis glandularis. Its relationship to bladder carcinoma]

A 41-year-old male was admitted to the hospital for frequent urination and severe retardation before voiding. Roentgenography revealed exophytic lesions which were located mainly in the trigone of the bladder, and he underwent transurethral resection. The pathological diagnosis was cystitis glandularis. There was no literature which reported cystitis glandularis causing urinary disturbance. This case, moreover, had been diagnosed as cystitis glandularis 13 years before by endoscopical biopsy. The origin of cystitis glandularis and its potentiality as a pre-malignant lesion were discussed from the clinical course for over 10 years.
