The sections show appendiceal mucosa with focal ulceration, as demonstrated by intraluminal debris and neutrophils, and marked reactive mucosal/submucosal lymphoid hyperplasia. There are no granulomas and no crypt architectural changes of chronic inflammation. The muscularis propria is not infiltrated by inflammatory cells, nor is the serosal surface. The proximal resection margin is intact. Ganglion cells are present. | The sections show appendiceal mucosa with focal ulceration, as demonstrated by intraluminal debris and neutrophils, and marked reactive mucosal/submucosal lymphoid hyperplasia.

- Acute appendicitis with acute periappendicitis, reactive epithelial changes, focally prominent benign neural tissue | |||
and marked active mucosal inflammation, see comment. | |||
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. | |||
