As per basic Gallbladder.
Microscopic evaluation
Classify cholecystitis as acute, chronic or both acute and chronic.
Findings in acute cholecystisis
Main initial features are edema and hemorrhage.[1]
- Initially often also congestion and fibrin deposition in and around the muscular layer.[2]
- Later often necrosis of the mucosa and and deeper layers, with neutrophils.[2]
- Variable reactive epithelial changes, which may resemble dysplasia.[2]
There may be fresh thrombi within small veins.[2]
Findings in chronic cholecystitis
Typical features are:[3]
- Smooth muscle hypertrophy in the muscularis
- Mild inflammatory infiltrates
- Rokitansky-Aschoff sinuses
Other findings favoring the diagnosis are:[3]
- Granulomas (from ruptured Rokitansky-Aschoff sinuses) strongly favor the diagnosis.
- Hyalinized collagen
- Dystrophic calcification
- Lymphoid aggregates
- Atrophic and/or ulcerated mucosa
- Metaplastic changes, such as gastric or intestinal mucosa
For a general gallbladder screening, see gallbladder.
Lymph nodes
Look for reactive lymphadenopathy or metastasis. Further information: Lymph node
