Other structures referred to as tonsils are the cecal, lingual, esophageal, paraepiglottic, pharyngeal and tubal lymphoid aggregations.
2. a small mass of tissue.

cecal tonsil
the accumulated mass of lymphoid tissue in the wall of cecum especially the proximal segment of the avian cecum.
cerebellar tonsil
a rounded mass forming part of the cerebellum on its inferior surface.
esophageal tonsil
large volume of lymphoid tissue in the caudal segment of the duck's esophagus.
follicular tonsil
a tonsil bearing numerous invaginations of its surface epithelium (fossulae) each surrounded by lymphoid tissue to form a follicle, as in the palatine tonsils of cattle or the lingual tonsils of the horse.
lingual tonsil
diffuse collection of lymphoid tissue near the tongue root of most mammals.
palatine tonsil
see palatine tonsil.
paraepiglottic tonsil
a collection of lymphoid tissue craniolateral to the epiglottic base.
pharyngeal tonsil
a collection of lymphoid tissue in the roof of the nasopharynx in pigs.
