At left is a micrograph of spleen with hyaline deposition (pink material at top of image) in association with inflammation (hyaloserositis), using H&E stain. At right is a micrograph of a kidney with arterial hyaline (hyaline arteriolosclerosis), using PAS stain.

A hyaline substance is one with a glassy appearance. The word is derived from Template:Langx, and Template:Langx.[1][2]

Histopathology

Hyaline cartilage is named after its glassy appearance on fresh gross pathology.[3] On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining.

Botany

In botany, hyaline refers to thin and translucent plant parts, such as the margins of some sepals, bracts and leaves.[citation needed]
