'''Tonsillitis''' is common and a reason the tonsils are removed (tonsillectomy). Malignancy is rare if not suspected; thus, [[tonsil]]s can be considered a [[ditzel]]. | |||
==General== | |||
*Commonly removed (tonsillectomy) when enlarged. | |||
*Very low probability of malignancy (<0.2%) in tonsilectomies in individuals <19 years old if no clinical suspicion.<ref name=pmid15963574>{{Cite journal | last1 = Erdag | first1 = TK. | last2 = Ecevit | first2 = MC. | last3 = Guneri | first3 = EA. | last4 = Dogan | first4 = E. | last5 = Ikiz | first5 = AO. | last6 = Sutay | first6 = S. | title = Pathologic evaluation of routine tonsillectomy and adenoidectomy specimens in the pediatric population: is it really necessary? | journal = Int J Pediatr Otorhinolaryngol | volume = 69 | issue = 10 | pages = 1321-5 | month = Oct | year = 2005 | doi = 10.1016/j.ijporl.2005.05.005 | PMID = 15963574 }}</ref> | |||
==Gross== | |||
*Symmetrical and equal size. | |||
Note: | |||
*Gross exam is considered sufficient if there is no asymmetry.<ref name=pmid14608541>{{Cite journal | last1 = Williams | first1 = MD. | last2 = Brown | first2 = HM. | title = The adequacy of gross pathological examination of routine tonsils and adenoids in patients 21 years old and younger. | journal = Hum Pathol | volume = 34 | issue = 10 | pages = 1053-7 | month = Oct | year = 2003 | doi = | PMID = 14608541 }}</ref> | |||
==Microscopic== | |||
Features: | |||
*Follicular hyperplasia - see ''[[lymph node pathology]]''. | |||
*+/-Colonies (clusters) of [[actinomycetes]] in the tonsillar crypts. | |||
DDx: | |||
*Non-Hodgkin [[lymphoma]].<ref name=pmid20426908>{{Cite journal | last1 = Wang | first1 = XY. | last2 = Wu | first2 = N. | last3 = Zhu | first3 = Z. | last4 = Zhao | first4 = YF. | title = Computed tomography features of enlarged tonsils as a first symptom of non-Hodgkin's lymphoma. | journal = Chin J Cancer | volume = 29 | issue = 5 | pages = 556-60 | month = May | year = 2010 | doi = | PMID = 20426908 }}</ref> | |||
*Others - see ''[[tonsil]]''. | |||
==IHC== | |||
If there is a clinical suspicion - a panel to exclude (small cell) non-Hodgkin lymphomas: | |||
*CD3. | |||
*CD20. | |||
*CD5. | |||
*CD10. | |||
*CD23. | |||
*Cyclin D1. | |||
