			Comment:
			The sections show marked active mucosal inflammation (microabscesses). This may be acute appendicitis only; however, the possibility of a secondary inflammatory process (infection, ischemia, inflammatory bowel disease, iatrogenic causes) should be considered. The specimen is NEGATIVE for granulomatous inflammation. Clinical correlation is recommended.

			The sections show reactive mucosal/submucosal lymphoid hyperplasia and submucosal fibromuscular hyperplasia. There is focal granulation tissue formation and intestinal crypt changes, including branching, as seen in repair. Scattered hemosiderin-laden macrophages are present. The muscularis propria is not infiltrated by inflammatory cells, nor is the serosal surface. The proximal resection margin is intact. Ganglion cells are present.

			Vermiform appendix, (interval) appendectomy - lymphoid hyperplasia with fibromuscular hyperplasia, consistent with recent appendicitis.
