title: [Cystitis cystica--a premalignant condition?].
abstract: Although cystitis cystica is considered to be a premalignant disease of the urinary bladder, remarkably few reports document the progression from cystitis cystica and glandularis to carcinoma of the bladder. We describe three patients where cystitis cystica was demonstrated 12, three and one month before diagnosis of cancer. We believe cystitis cystica reflects mobilization of the humoral immune defence mechanism in response to various agents, among these a subclinical malignant tumour.
