This appendix was removed surgically. The patient presented with abdominal pain that initially was generalized, but then localized to the right lower quadrant, and physical examination disclosed 4+ rebound tenderness in the right lower quadrant. The WBC count was elevated at 11,500. Seen here is acute appendicitis with yellow to tan exudate and hyperemia, including the periappendiceal fat superiorly, rather than a smooth, glistening pale tan serosal surface.
