Hyalin is a poorly understood and even poorly defined word. It means “glassy or translucent substance” and has been applied to proteins that are amorphous and stain in such a fashion but lack other distinguishing characteristics. Hyaline is the corresponding adjective. In the skin, a hodgepodge of different materials have been identified. Some authors include amyloid and gouty tophi under hyalins; others specifically exclude these substances. The overproduction of carbohydrate-rich glycoproteins is the usual explanation for their genesis. Several exceedingly rare disorders are traditionally considered “hyalinoses”.
