[Interstitial cystitis. Apropos of 11 cases].

The authors report eleven cases of interstitial cystitis, and discuss two different aspects of the disease: the classic form, with reduced bladder capacity and Hunner's ulcer, and the early form, which is diagnosed by cystoscopy under general anesthesia, and bladder biopsy. The hallmark of this early form is the discovery of multiple petichiae in the bladder mucosa during the second distension of the bladder.
