SIMULTANEOUS LYMPHOCYTIC GASTRITIS AND LY MPHOCYTIC COLITIS, WITH DEVELOPMENT OF COLLAGENOUS COLITIS

Lymphocytic gastritis and lymphocytic colitis are two rare disorders o f unknown etiology, only diagnosable by histology. Simultaneous occurr ence of lymphocytic colitis and lymphocytic gastritis has not been des cribed up to now. A 69-year-old female patient was examined because of crampy abdominal pain and watery diarrhea. Laboratory tests did not r eveal an etiology and in colonoscopy the colon and terminal ileum were normal. Histology disclosed lymphocytic colitis. Esophagogastroduoden oscopy showed erosive bulbitis. Biopsies of the stomach revealed lymph ocytic gastritis. A second colonoscopy one year later showed the devel opment of collagenous colitis.
