Efficacy of Leishman Stain in Cytology - A 30 Years Experience
Dr. Niranjan Rout
Professor & Head Of Pathology, Acharya Harihar Regional Cancer Centre, Cuttack – 753007, Odisha, India
Abstract: Leishman stain is one of the Romanowsky stains and is used extensively for interpretation of
hematology smears in both urban and rural laboratories. In contrast Papanicolaou and HE(Hematoxylin &
Eosin) method of staining are often not available in rural laboratories in resource constrained regions.
With this in mind we started using the Leishman stain. In the initial years, we stained cytosmears simultaneously
with Leishman stain and Papanicolaou method and interpreted and compared our observations.
We have been using Leishman staining technique to interpret cytosmears for last 30 years and also applied this
technique to interpret cytology smears in health camps organised at community level in rural areas.Thus,
Leishman staining is a simple, quick and inexpensive staining teachnique easily available in both urban and
rural laboratories which can be used as an efficacious tool to interpret cytosmears.
Cytological interpretation relies heavily on the quality and appearance of the staining technique. Three
staining techniques are in routine practice - Papanicolaou method for alcohol fixed wet smears, air dried smears
stained with Romanowsky stains and Hematoxyline-Eosin (HE) stain.
Leishman stain is one of the Romanowsky stains and is used extensively for interpretation of
hematology smears in both urban and rural laboratories. In contrast Papanicolaou and HE method of staining are
often not available in rural laboratories in resource constrained regions. With this in mind we started using the
Leishman stain to interpret cytosmears since 1984. [1]
In this method, similar to the blood smears the cytosmears are air-dried and put on a staining tray, and
the Leishman stain is then poured on to cover the cytosmear. Thirty seconds is allowed for fixation after which
an equal amount of distilled water is added. After 3 to 5 minutes, the slides are washed with running tap water
and examined under the microscope.
In the initial years, we stained cytosmears simultaneously with Leishman stain and Papanicolaou
method and interpreted and compared our observations. [2] In one of our study, [3] while comparing the
outcome from 882 smears from different lesions stained by both Leishman method and Papanicolaou method of
staining (Fig.1,a,b,c,d & Fig.2,e,f,g,h Fig.3,I,j,k,l), we observed that in only 4.7% cases we failed to reach at a
diagnosis with Leishman stain. In some of these cases, nuclear details were not clear. Many pathologists feel
that fine nuclear structure is not well demonstrated in air dried Giemsa Stains,[4] but on the other hand, nuclear
characteristics such as chromatin, nucleoli and nuclear membrane are better visualised in wet-fixed pap-stained
smears.[5] We have been using Leishman staining technique to interpret cytosmears for last 30 years and also
applied this technique to interpret cytology smears in health camps organised at community level in rural areas.
Thus, Leishman staining is a simple, quick and inexpensive staining technique easily available in both
urban and rural laboratories which can be used as an efficacious tool to interpret cytosmears.

Efficacy of Leishman Stain in Cytology - A 30 Years Experience

  • 1. International Journal of Pharmaceutical Science Invention ISSN (Online): 2319 – 6718, ISSN (Print): 2319 – 670X www.ijpsi.org Volume 5 Issue 6 ‖October 2016 ‖PP. 01-03 www.ijpsi.org 1 | P a g e Efficacy of Leishman Stain in Cytology - A 30 Years Experience Dr. Niranjan Rout Professor & Head Of Pathology, Acharya Harihar Regional Cancer Centre, Cuttack – 753007, Odisha, India Abstract: Leishman stain is one of the Romanowsky stains and is used extensively for interpretation of hematology smears in both urban and rural laboratories. In contrast Papanicolaou and HE(Hematoxylin & Eosin) method of staining are often not available in rural laboratories in resource constrained regions. With this in mind we started using the Leishman stain. In the initial years, we stained cytosmears simultaneously with Leishman stain and Papanicolaou method and interpreted and compared our observations. We have been using Leishman staining technique to interpret cytosmears for last 30 years and also applied this technique to interpret cytology smears in health camps organised at community level in rural areas.Thus, Leishman staining is a simple, quick and inexpensive staining teachnique easily available in both urban and rural laboratories which can be used as an efficacious tool to interpret cytosmears. Cytological interpretation relies heavily on the quality and appearance of the staining technique. Three staining techniques are in routine practice - Papanicolaou method for alcohol fixed wet smears, air dried smears stained with Romanowsky stains and Hematoxyline-Eosin (HE) stain. Leishman stain is one of the Romanowsky stains and is used extensively for interpretation of hematology smears in both urban and rural laboratories. In contrast Papanicolaou and HE method of staining are often not available in rural laboratories in resource constrained regions. With this in mind we started using the Leishman stain to interpret cytosmears since 1984. [1] In this method, similar to the blood smears the cytosmears are air-dried and put on a staining tray, and the Leishman stain is then poured on to cover the cytosmear. Thirty seconds is allowed for fixation after which an equal amount of distilled water is added. After 3 to 5 minutes, the slides are washed with running tap water and examined under the microscope. In the initial years, we stained cytosmears simultaneously with Leishman stain and Papanicolaou method and interpreted and compared our observations. [2] In one of our study, [3] while comparing the outcome from 882 smears from different lesions stained by both Leishman method and Papanicolaou method of staining (Fig.1,a,b,c,d & Fig.2,e,f,g,h Fig.3,I,j,k,l), we observed that in only 4.7% cases we failed to reach at a diagnosis with Leishman stain. In some of these cases, nuclear details were not clear. Many pathologists feel that fine nuclear structure is not well demonstrated in air dried Giemsa Stains,[4] but on the other hand, nuclear characteristics such as chromatin, nucleoli and nuclear membrane are better visualised in wet-fixed pap-stained smears.[5] We have been using Leishman staining technique to interpret cytosmears for last 30 years and also applied this technique to interpret cytology smears in health camps organised at community level in rural areas. Thus, Leishman staining is a simple, quick and inexpensive staining technique easily available in both urban and rural laboratories which can be used as an efficacious tool to interpret cytosmears.
