Glossitis in immunocompromized individuals. Treatment is with systemic aciclovir. Strawberry tongue (also called raspberry tongue), refers to glossitis which manifests with hyperplastic (enlarged) fungiform papillae, giving the appearance of a strawberry. White strawberry tongue is where there is a white coating on the tongue through which the hyperplastic fungiform papillae protrude. Red strawberry tongue is where the white coating is lost and a dark red, erythematous surface is revealed, interspaced with the hyperplastic fungiform papillae. White strawberry tongue is seen in early scarlet fever (a systemic infection of group A β- hemolytic streptococci), and red strawberry tongue occurs later, after 4–5
Neurogenic inflammation Neurogenic inflammation Neurogenic inflammation is inflammation arising from the local release by afferent neurons of inflammatory mediators such as Substance P, Calcitonin Gene-Related Peptide (CGRP), neurokinin A (NKA), and endothelin-3 (ET-3). TRPA1 channels stimulated by lipopolysaccharide (LPS) may also cause acute neurogenic inflammation. Once released, these neuropeptides induce the release of histamine from adjacent mast cells. In turn, histamine evokes the release of substance P and calcitonin gene-related peptide; thus, a bidirectional link between histamine and neuropeptides in neurogenic inflammation is established. Neurogenic inflammation appears to play an important role in the pathogenesis of numerous diseases including migraine, psoriasis, asthma,
