Development of collagenous colitis in a cecoplasty of a patient with interstitial cystitis.

We present the case of a 45-yr-old female patient with a 23 yr history of interstitial cystitis that multiple surgical procedures, including a ceco-cystoplasty, were unable to cure. After a cystectomy was performed, histological examination of the bladder showed the development of collagenous colitis. Although the etiology of both interstitial cystitis and collagenous colitis is unknown, this report postulates an association between these two conditions.
