title: Interstitial cystitis is bladder pain syndrome with Hunner's lesion.
abstract: The contents and understanding of the term, interstitial cystitis, have undergone major changes during the past 100 years, moving from a chronic, true inflammatory bladder disorder to an extensive syndrome with lower urinary tract pain. Comments on this development are presented. From examples in the literature, some important features of classic interstitial cystitis are outlined. The more inclusive attitude of later decades has drawn desirable attention to the entire spectrum of disorders resulting in bladder pain. The wish to include all of them into one handy entity has unfortunately resulted in much scientific and clinical confusion, though. It is noted that originally interstitial cystitis represented the Hunner type of disease. Today, there is agreement that the classic type of interstitial cystitis with Hunner's lesions, bladder pain syndrome type 3C according to current terminology, stands out as a well-defined phenotype; it has to evaluated separately in clinical studies and practice, as treatment requirements differ importantly between this and other phenotypes.
