The torus tubarius is very close to the tubal tonsil, which is sometimes also called the tonsil of (the) torus tubarius.

The set of lymphatic tissue known as Waldeyer's tonsillar ring includes the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsil.

The tubal tonsil is one of the four main tonsil groups comprising Waldeyer's tonsillar ring, which includes the Palatine tonsil, the Lingual tonsil, the Pharyngeal tonsil, and the Tubal tonsil.
