Interval appendectomy is an appendectomy following the presentation of acute appendicitis.[1]
General
- Done to exclude neoplasm and recurrent appendicitis.[2]
Microscopic
Features:
- Muscularis propria eosinophils and/or plasma cells.
- +/-Muscularis propria neutrophils.
DDx:
- Negative appendectomy - specimen should be submitted in toto, no lymphoid hyperplasia, history is essential.
- Adenovirus appendicitis - lymphoid hyperplasia.
- Mucinous tumour - usu. apparent on gross.
- Appendiceal neuroendocrine tumour.
- Granulomatous appendicitis.
- Crohn's disease of the appendix.
Sign out
Vermiform Appendix, Appendectomy: - Benign appendix with mild mixed muscularis inflammation (plasma cells, eosinophils, possible rare neutrophils), see comment. Comment: The operative report describes an interval appendectomy; the finds would be compatible with that.
