Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Microscopic evaluation
- Look for signs of active (or acute) and/or chronic colitis:
Signs of active (or acute) colitis:
- Neutrophilic cryptitis
- Neutrophilic crypt abscesses
- Ulceration or granulation tissue
- Ischemic changes (including superficial necrosis, hemorrhage, crypt shrinkage/dropout, fibrin thrombi)
Signs of chronic colitis:
- Abnormal crypt orientation a
- Abnormal crypt branching
- Paneth cell or gastric metaplasia (only apllies in the left colon and rectum)
- Elevation of crypts relative to the muscularis mucosa
Microscopy report
Example of a normal sample, when colitis was suspected in the referral:
| ( Optionally: Colonic/Rectal mucosa without significant histopathologic changes.) Negative for acute and chronic colitis. |
Example of findings of both active and chronic colitis:
| (Ascending, transverse, descending, and sigmoid colon, biopsies:) Mild chronic active colitis, with associated cryptitis and crypt abscesses. (Negative for ulceration, granulomata and dysplasia.) |
