 File:IPLab3AcuteAppendicitis1.jpg|This is a gross photograph of the appendix which was removed from this patient with acute appendicitis. Note the rough, shaggy material (arrows) on the surface due to deposition of fibrin and inflammatory cells.
-File:IPLab3AcuteAppendicitis2b.jpg|This is a low-power photomicrograph of a normal appendix on the right and an appendix with acute inflammatory response on the left. Note the abundant blue-stained lymphoid tissue beneath the mucosal layer and the absence of blue-staining cells in the submucosal layer of the normal appendix. Compare this with the extensive distribution of cells throughout the wall of the appendix with acute appendicitis. The blue color is due to the presence of many inflammatory cells, although at this low power these individual cells cannot be specifically identified.
+File:IPLab3AcuteAppendicitis2b.jpg|This is a low-power photomicrograph of a normal appendix on the right and this appendix with an acute inflammatory response on the left. Note the focal areas of blue-stained lymphoid tissue which is normal for the normal appendix. Compare this with the increased size of the inflamed appendix (left) due to inflammatory cells and edema.
-File:IPLab3AcuteAppendicitis3b.jpg|This is a photomicrograph showing the serosal surface of the appendix with the layer of fibrinopurulent exudate noted in the gross photo (1).  The muscularis (M) and the submucosa (S) also have a robust inflammatory cell infiltrate.

 File:IPLab3AcuteAppendicitis4b.jpg|This photomicrograph of the lumen shows the mucosal surface with a small area of normal mucosal epithelium (arrow). This area is surrounded by the ulcerated mucosa with inflammatory infiltrates comprising primarily neutrophils with a few lymphocytes and macrophages.
 File:IPLab3AcuteAppendicitis5b.jpg|TThis higher-power photomicrograph of the mucosal surface shows the loss of normal mucosal epithelium (arrows) and the inflammatory infiltrate. The principal inflammatory cell in this case of acute appendicitis is the neutrophil.

 == Clinical Summary ==
-This 11-year-old male was admitted to the hospital with a complaint of 8 hours of severe pain in the right lower quadrant of the abdomen accompanied by nausea, vomiting, and diarrhea. Additional features on admission included a temperature of 101° F and a leukocytosis of 21,200 cells/mm³ with a shift to the left. An exploratory laparotomy revealed an inflamed appendix, retrocecal in location, which was adherent to the wall of the colon.

On admission his temperature was 101° F and he had a leukocytosis of 21,200 cells/cmm with a shift to the left.  An exploratory laparotomy revealed an inflamed appendix, retrocecal in location, which was adherent to the wall of the colon.

-File:IPLab3AcuteAppendicitis3.jpg|This is a photomicrograph of an appendix exhibiting acute inflammation. Note that there are only remnants of mucosal tissue identifiable along the luminal border of this specimen. There is an extensive infiltration of leukocytes in this tissue which cannot be specifically identified at this low power. Note that the surface is very roughened and has deposits of fibrin.

 File:IPLab3AcuteAppendicitis7.jpg|This is a gross photograph of the open abdominal cavity of a patient with acute appendicitis. In this patient, there had been rupture of the appendix with spillage of intestinal contents into the abdominal cavity. This spillage resulted in an acute abdomen with widespread inflammation throughout the abdominal cavity. Note the roughened surface of the mesenteric tissue (arrow) due to deposition of fibrin over much of the surface.
 File:IPLab3AcuteAppendicitis8.jpg|This is a gross photograph of another example of peritonitis. Again note the fibrinosuppurative exudate covering the abdominal organs (arrows).
