Pathology of Chronic Cholecystitis

Dr Sampurna Roy MD

 

Chronic cholecystitis is rarely seen in the absence of lithiasis.

The associated stones are of the mixed or combined type.

The female to male ratio is 3 to 1 with the peak incidence in the 5th and 6th decades.

The gall bladder may be shrunken and fibrotic or distended depending on its level of obstruction and the duration of disease.

Rokitansky-Aschoff sinuses are usually present with or without inspissated bile.

Bile granulomas may be seen in relation to Rokitansky-Aschoff sinuses.

There is variable fibrosis throughout the wall. The chronic inflammation is variable.

There may be changes of previous acute cholecystitis.

Ulcer associated cell lineage may be seen in association with intestinal metaplasia and argentaffin cells.

Chronic follicular cholecystitis occasionally occurs where prominent lymphoid follicles are seen throughout the wall. This is more common in patients with typhoid fever. These need to be differentiated from gallbladder involvement by malignant lymphoma. Lymphoma of Gallbladder

Localized tissue reactions with cholesterol crystals may be seen within the thickened fibrous wall underlying an ulcer.

Malakoplakia is another morphologic form of chronic cholecystitis, with formation of Michaelis-Gutmann bodies.
