Blood 1988 May;71(5):1329-33 Abstract quote Follicular mucinosis is a condition characterized by the abnormal accumulation of acidic mucopolysaccharides in hair follicles Core tip: Paneth cells physiologically locate in small intestinal crypts. Wnt signalling promotes their differentiation and movement into crypts, whereas Notch activities antagonise Paneth cell maturation. The cells essentially contribute to crypt morphogenesis and intestinal homeostasis, sharpening the microbiome by secreting antimicrobial peptides, like defensins, and crypt fission It has been estimated that the ratio of NB to GN is approximately 6:1 to 10:1 (, 110 111 ). GN occurs in the same anatomic locations as NB and GNB, although at different frequencies. The most common locations are the posterior mediastinum (41.5% of cases), retroperitoneum (37.5%), adrenal gland (21%), and neck (8%)
