Acute appendicitis with periappendicits - children
Microscopic description
The sections show appendiceal mucosa with focal ulceration and reactive mucosal lymphoid hyperplasia. The muscularis propria is infiltrated by inflammatory cells (including, lymphocytes, neutrophils and eosinophils), which are also found at the serosal surface. The proximal resection margin is intact. Ganglion cells are present.
Final diagnosis
Vermiform appendix, appendectomy - acute appendicits with periappendicitis.
Checklist approach - to the routine appendix
Microscopic description
Neutrophils in muscularis propria - present.
Inflammation at the serosal surface - present.
Site of perforation identified - no.
Granulomatous inflammation - not identified.
Crypt architectural changes - not present.
Lymphoid hyperplasia - present.
Submucosal fibrosis - absent.
Fecalith - not identified.
Infectious organisms - not identified on routine stains.
Resection margin viable - yes.
Ganglion cells - present.
Final diagnosis
Vermiform appendix, appendectomy:
- Acute appendicits.
- Acute periappendicitis.
Sort of negative appy - GS
Microscopic description
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.
Final diagnosis
Vermiform appendix, appendectomy - acute inflammation, see microscopic description.
Negative appy
Microscopic description
The sections show normal large bowel wall with abundant mucosal and submucosal lymphoid tissue. The muscularis propria is not infiltrated by inflammatory cells, nor is the serosal surface. The proximal resection margin is intact. Ganglion cells are present.
Final diagnosis
Vermiform appendix, appendectomy - no pathology.
Interval appy - GS
Microscopic description
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.
Final diagnosis
Vermiform appendix, (interval) appendectomy - lymphoid hyperplasia with fibromuscular hyperplasia, consistent with recent appendicitis.
