Eosinophilic (Greek suffix -phil-
The Greek root "-Phil-" originates from the Greek word meaning "love". For example, Philosophy (along with the Greek root "-soph-" meaning "wisdom") is the study of human customs and the significance of life. One of the most common uses of the roo ...

A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials app ...

In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name ''organelle'' comes from the idea that these structures are parts of cells, as organs are to the body, hence ''organelle,'' the ...
s after they have been washed with eosin, a dye
A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution an ...

A muscle cell is also known as a myocyte when referring to either a cardiac muscle cell (cardiomyocyte), or a smooth muscle cell as these are both small cells. A skeletal muscle cell is long and threadlike with many nuclei and is called a muscl ...
. ''Eosinophilic'' describes the appearance of cells and structures seen in histological sections that take up the staining dye eosin. Such eosinophilic structures are, in general, composed of protein.
Eosin is usually combined with a stain called hematoxylin to produce a hematoxylin- and eosin-stained section (also called an H&E stain, HE or H+E section). It is the most widely used histological stain for a medical diagnosis. When a pathologist examines a biopsy of a suspected cancer, they will stain the biopsy with H&E.
Some structures seen inside cells are described as being eosinophilic; for example, Lewy and Mallory bodies
In histopathology, a Mallory body, Mallory-Denk body, and Mallory's hyaline, is an inclusion found in the cytoplasm of liver cells. Mallory bodies are damaged intermediate filaments within the liver cells.
