From the pathological features for example existence of germinal center lymphoid tissue and crypt involving lymphoepithelial symbiosis we diagnosed that the lesion was a hyperplasia of ectopic tonsillar tissue. Conclusions Although ectopic tonsillar tissue of the hypopharynx is relatively rare it should be kept in mind during differential diagnosis.
