[Aseptic abscesses in eight patients with cryptogenic inflammatory bowel disease].

The aim of this study was to describe aseptic abscess related pathologic changes observed in eight patients with inflammatory bowel disease. Patients were 3 men and 5 women whose age ranged from 15 to 60. Seven had Crohn's disease and one had ulcerative colitis. Diagnosis preceded abscess onset in two cases. Bacteriological investigations were performed in all cases and were negative. In all biopsy specimens, Hematoxylin and Eosin, PAS, Grocott, Whartin-Starry, Gram and Ziehl-Nielsen stains were negative. Histological changes were comparable and could be divided into early and older lesions. After discussion of the differential diagnoses, the hypothesis of a new clinico-pathological entity is suggested.
