Lymphatic nodules are the secondary lymphatic tissues that lack any surrounding capsule and are present like egg-shaped tissue masses. The lymphatic nodules present in the lining of some organ systems such as gastrointestinal tract, urinary system, and the respiratory airways are called mucosa-associated lymphatic tissue (MALT) as these lymphatic tissues are present in their mucous membranes.
For example, Peyer patches and tonsils. Peyer's patches are the lymphatic nodules present in intestinal wall, and the appendix. Tonsils are the secondary lymphatic tissues present in a ring about pharynx.
