The Solitary lymphatic nodules (or "solitary follicles") are structures found in the small intestine and large intestine.

The solitary lymphatic nodules are found scattered throughout the mucous membrane of the small intestine, but are most numerous in the lower part of the ileum.

The solitary lymphatic nodules of the large intestine are most abundant in the cecum and vermiform process, but are irregularly scattered also over the rest of the intestine.
