LEISHMAN STAIN Meaning and
Definition
-
Leishman stain refers to a specialized histological dye that is commonly used in medical laboratories for the detection and diagnosis of certain parasites, specifically those that cause a disease known as leishmaniasis. This stain takes its name from the British pathologist Sir William Boog Leishman, who first introduced and adapted this technique in the late 19th century.
Leishman stain is primarily composed of a mixture of methylene blue and eosin dyes, which when combined, create a purple color. It is a Romanowsky stain, a type of dye staining technique that is widely employed in cytology and histopathology to examine the microscopic structure of cells. The distinctive feature of Leishman stain is its ability to stain different cell components with varying colors, allowing for the differentiation and visualization of certain microscopic organisms or cellular structures.
In the context of leishmaniasis, the Leishman stain is used to detect the parasitic microorganisms called Leishmania in tissue samples, such as blood smears or bone marrow aspirates. When applied to these samples, the dye selectively stains the nucleus of cells purple, while other structures in the cytoplasm take on a pinkish hue. By observing and analyzing the stained cells under a microscope, experts can identify the presence of Leishmania parasites and determine their quantity, aiding in the accurate diagnosis and subsequent treatment of leishmaniasis.

Etymology of LEISHMAN STAIN
The word "Leishman stain" is named after its inventor, William Boog Leishman. Born in Scotland in 1865, Leishman was a physician and pathologist who made significant contributions to the field of medicine. He developed the Leishman stain, a purple dye used to stain blood smears for the identification and diagnosis of various blood disorders.
The stain was first described by Leishman in 1901 as a modification of the Romanowsky stain, which was originally developed by a Russian scientist named Dmitri Romanowsky. Leishman's modification involved adding new ingredients and altering the staining procedure to improve the visibility and differentiation of the various cell types in blood smears.
Due to its effectiveness and wide usage, the modified stain became known as the "Leishman stain".
