Tonsillitis is common and a reason the tonsils are removed (tonsillectomy).
Malignancy in tonsils is rare if not suspected; thus, tonsils can be considered a ditzel.
General
- Commonly removed (tonsillectomy) when enlarged.
- Tonsillitis is a clinical diagnosis.
- Very low probability of malignancy (<0.2%) in tonsilectomies in individuals <19 years old if no clinical suspicion.[1]
Gross
- Symmetrical and equal size.
Note:
- Gross exam is considered sufficient if there is no asymmetry if individual younger than 21 years of age.[2]

Microscopic
Features:
- Follicular hyperplasia - see lymph node pathology.
- +/-Colonies (clusters) of actinomycetes in the tonsillar crypts.
DDx:
IHC
If there is a clinical suspicion - a panel to exclude (small cell) non-Hodgkin lymphomas:
- CD3.
- CD20.
- CD5.
- CD10.
- CD23.
- Cyclin D1.
