Polyps are abnormal growths that start in the inner lining of the colon or rectum. Some polyps are flat while others have a stalk.Background: Ectopic lymphoid tissues (eLTs) and associated follicular helper T (T FH) cells contribute to local immunoglobulin hyperproduction in nasal polyps (NPs).Follicular regulatory T (T FR) cells in secondary lymphoid organs counteract T FH cells and suppress immunoglobulin production; however, the presence and function of T FR cells in eLTs in peripheral diseased tissues remain poorly ...Morphologic characteristics of sessile serrated adenoma/polyps.
