Palatine Tonsil and Oropharynx

  • L. Michaels
Part of the Current Histopathology book series (CUHI, volume 16)


The palatine tonsil is composed of lymphoid tissue within which are channels lined by squamous epithelium—crypts—that open onto the surface (Figure 9.1). It is part of a ring of lymphoid tissue in the oral cavity and nasopharynx—Waldeyer’s ring—which includes also the lingual tonsil at the base of the tongue and the pharyngeal tonsil or adenoid in the nasopharynx. There are about 20 crypts reaching the deepest part of the structure. Submucosal glands lie in the peripheral part.
