What is the morphology of appendicitis?

The morphology of appendicitis typically involves inflammation and swelling of the appendix, with associated changes in its wall structure. Histologically, it is characterized by neutrophilic infiltration, necrosis, and sometimes the presence of abscesses. The lumen may be obstructed by fecaliths or other materials, leading to increased pressure and potential perforation. In chronic cases, fibrosis and scarring may be observed.
