Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Gross proccessing
Standard sections if the appendix appears inflamed and there are no signs of malignancy. Further information: Appendix
Microscopic evaluation
- Evaluate depth of the inflammation.
- Look for any perforation of the wall.
- (Attempt to specify the type of appendicitis as either of the following:)
Types
Pattern | Gross pathology | Light microscopy | Clinical significance |
---|---|---|---|
Acute intraluminal inflammation | None visible |
|
Probably none |
Acuta mucosal inflammation | None visible |
|
May be secondary to enteritis. |
Suppurative acute appendicitis | May be inapparent.
|
|
Can be presumed to be primary cause of symptoms |
Gangrenous/necrotizing appendicitis |
|
|
Will perforate if untreated |
Periappendicitis | May be inapparent.
|
|
Probably secondary to other disease |
Eosinophilic appendicitis | None visible |
|
Possibly parasitic, or eosinophilic enteritis. |
