Lymphoid aggregate polyp.

Lymphoid polyps. A lymphoid polyp (lymphoid hyperplasia, benign lymphoma) is a benign, focal or diffuse condition that occur typically where clusters of lymphoid follicles are present (terminal ileum, rectum) (Corman 1998). A lymphoid polyp is characterized radiographically by small, uniform localized or generalized polypoid lesions.
