A 5-year-old boy underwent tonsila pharyngea

(pharyngeal tonsil) surgery. Unfortunately, as a

result of frequent respiratory infections, this tonsil became enlarged, which

led to nasal obstruction, where the boy breathed only through his mouth and

snored heavily at night. The prolonged mouth breathing increased his susceptibility

to respiratory infections and also led to the remodelling of the palate and

upper dental arch. In addition, the enlarged tonsil covered the opening of the

Eustachian tube, leading to recurrent otitis media and hearing loss. The

surgery went perfectly fine, however, the removed tonsil was sent to pathology

for histological examination due to its size. What epithelium is normally found

on the surface of this tonsil?
