Histopathology of the appendix
Site of inflammation and occasionally tumours.
Incidental neuroendocrine tumours ('carcinoid'), is rare at <1% (5/1237, 20/1350, and 7/1485.), but when found, is commonly at the tip. If at the tip and less than 1-2cm, further intervention is usually not required. There is uncertainty over the indications for a right hemicolectomy, but these may include:
- large tumours (>2cm)
- tumours at the base
- invasion into the mesoappendix
- high-grade histological features
- goblet adenocarcinoid sub-type
