Diagnosis: Chronic glandular cystitis of the usual and intestinal types with mucin extravasation.

    Comment: Chronic glandular cystitis is a frequent benign lesion of the urinary bladder. The intestinal type is less frequent and may be associated with mucin extravasation (Young RH et al. Florid cystitis glandularis of intestinal type with mucin extravasation: A mimic of adenocarcinoma, Am J Surg Pathol 20:1462-1468,1996). Cystitis glandularis may cause irritative symptoms, hematuria, and rarely hydronephrosis. It is most common in the trigone and blader neck. Although usually a microscopic finding, cystitis glandularis is occasionally visible grossly, and in occasional cases, a polypoid mass suggests a neoplasm.
