Large Cystitis Glandularis: a Very Rare Cause of Severe Obstructive Urinary Symptoms in an Adult

Cystitis glandularis is a very rare proliferative disorder of the mucus-producing glands within the mucosa and submucosa of urinary bladder epithelium. We report such a case of glandular cystitis with intestinal metaplasia masquerading as a bladder tumor in a young male patient who presented with severe obstructive urinary symptoms. Cystoscopy revealed a tumor well circumscribed, measuring 5 x 4 cm on the trigone. Transurethral resection of the mass was carried out and the histopathology suggested cystitis glandularis. The literature regarding this entity has been reviewed and the differential diagnosis was discussed. Short-term follow-up of the patient with sonography and cystoscopy showed no recurrence.
