We report a rare appearance of cystitis glandularis forming a tumorous lesion with blueberry spots in the urinary bladder. A 49-year-old woman was admitted to our hospital with pollakisuria and recurrent gross hematuria. Urine examination showed no pyuria. Computed tomography (CT) scan showed an extravesical invasive mass and cystoscopy revealed a non-papillary tumor with blueberry spots in the bladder. Transurethral resection (TUR) was performed. Histopathological examination revealed cystitis glandularis with cystitis cystica in the part. Postoperative CT scan and cystoscopy showed reduction of the mass in the bladder without any treatments. She is currently well with no evidence of tumor growth three months after TUR.
