A case of asymptomatic cystitis glandularis found incidentally with ultrasonography at a private clinic.

A 46-year-old man was transferred to our hospital because of a bladder mass. The mass could not be distinguished from a primary bladder tumor or a tumor invading from another organ with computed tomography, magnetic resonance, or cystoscopic examination. Transurethral resection of the mass was performed, and the pathological diagnosis was typical cystitis glandularis. The patient has been followed up with cytologic examination and ultrasonography, and after 10 months there has been no new growth of the mass or malignant change.
