Appendicitis may histopathologically be defined as neutrophilic infiltrates of the wall of the appendix in the correct clinical context.

Comprehensiveness
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 |
Acute 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.
|
|
If isolated, probably secondary to other disease |
Eosinophilic appendicitis | None visible |
|
Possibly parasitic, or eosinophilic enteritis. |
Chronic appendicitis[2] |
|
|
Should preferably correlate with long-term or recurrent symptoms. |
