Tongue, Hairy - NORD (National Organization for Rare Disorders)
Hairy tongue is an uncommon, kind status that is also known as black downy clapper or lingua nigra. This is not a comprehensive info since there are nearly 7,000 diseases considered infrequent in the U. We add new topics as we are able to do so, with the help of rare unwellness examination experts. It is characterised by deviant elongation and blackish or darkling dark-brown discoloration or "staining" of the thread-like elevations (filiform papillae) that screen about of the tongue's surface (dorsum linguae). Architectural arrangement of filiform papillae in connatural and negroid fuzzy glossa epithelium: analysis of differentiation pathways in a interlacing human animal tissue reported to their patterns of scleroprotein expression. If you are seeking information about a uncommon disease that is not in this database, we would suggest contacting the Genetic and Rare Diseases Information Center (GARD) at the National Institutes of Health. Such changes often set out at the rear (posterior) body part of the top of the tongue and extend toward the front (anterior) of the tongue's surface but never relate the undersurface. NIH has the most complete info of rare diseases in the U.
