crypt abscess

crypt abscess

A finding by light microscopy, which consists of aggregates of neutrophils (less commonly, eosinophils), fibrin and sloughed epithelial cells within a partially ruptured colonic gland. Crypt abscesses are more typical of ulcerative colitis than Crohn’s disease and other forms of inflammatory bowel disease, and may also occur in radiation colitis and Helicobacter spp infection.

Resection margin with severe Crohn disease activity, including cryptitis, crypt abscess, ulcer, lamina propria chronic inflammation, crypt distortion, and crypt dropout (hematoxylin-eosin, original magnification X100).
The mucosal biopsy specimens revealed glandular distortion and cryptitis with crypt abscess (Figure 2), which were compatible with UC.
The clinical course of GVHD involves the development of crypt abscess due to neutrophil infiltration, crypt loss, and eventually mucosal exfoliation.

(4) Thus, parenchymal tonsillar abscesses may occur through two different mechanisms: direct extension of a crypt abscess into the tonsillar parenchyma or seeding of bacteria throughout the tonsil via the bloodstream or lymphatics.
One of them is cytapheresis, which aims to suppress and reduce impaired immune responses in the diseased intestine by removing circulating activated leukocytes, especially granulocytes, which have been shown to cause intestinal crypt abscess.
The biopsy appearances of ulcerative colitis in the duodenum resemble those in the large bowel, consisting of diffuse active chronic inflammation including cryptitis and crypt abscess formation.
This field shows crypt dropout as well (hematoxylin and eosin, original magnification 200x); biopsies of the colon show cryptitis and crypt abscess with minimal crypt distortion.
(9) in their study of histopathological findings of chronic tonsillitis in palatine tonsils concluded that slight to moderate lymphocytic infiltrations in surface epithelium, crypt abscess and or diffuse lymphocytic infiltrations were pathognomic of chronic tonsillitis.
The ME classifications were significantly associated with the UC-pathognomonic microscopic features including severe mucosal inflammation, crypt abscess, and goblet cell depletion.
However, crypt abscess, crypt distortion, granulomas and amebic organisms were not seen.
