title: Chronic interstitial cystitis as an initial major manifestation of systemic lupus erythematosus.
abstract: Chronic interstitial cystitis (CIC) has been thought to result from autoimmune phenomena and its occurrence in systemic lupus erythematosus (SLE) has occasionally been recorded. We report a patient with SLE whose initial urinary symptoms were caused by CIC. Two of 3 patients (including ours) whose cases have been reported also had diarrhea, a common symptom in idiopathic CIC. All 3 patients had cutaneous and/or bladder vasculitis. CIC occurring in SLE seems to be due to immune complex deposition.
