Abstract
Background: The morphological features of keratinisation can impact histopathological diagnosis. Routine haematoxylin and eosin (H&E) stain has its limitations in moderately differentiated cases of oral squamous cell carcinoma (OSCC).
Aims: The aim of this study was to evaluate and compare the characteristics of staining and identification of keratin by routine H&E stain, Alcian Blue-Periodic Acid Schiff (AB-PAS), Ayoub-Shklar, and Modified Papanicolaou (PAP) stain in OSCC cases.
Material and methods: Overall, 30 cases of OSCC were included in experimental groups, and 20 cases of well-differentiated squamous cell carcinoma (WDSCC) and ten cases of moderately differentiated squamous cell carcinoma (MDSCC) and ten cases of normal keratinised oral mucosa (NKOM) were included in the control group. Histopathologicaly diagnosed cases of OSCC were selected, and tissue sections from each were prepared. Fisher's exact test was used for the statistical analysis.
Results and conclusions: We observed that the staining intensity was greater in Ayoub-Shklar in WDSCC and in MDSCC followed by modified PAP and AB-PAS-stained sections and the staining specificity was greater in modified PAP in WDSCC and in MDSCC followed by AB-PAS and Ayoub-Shklar in stained sections. We conclude that special stains like AB-PAS, Ayoub-Shklar, and modified PAP stain can prove to be a simple solution to detect the presence and pattern of keratin histologically. The efficacy of distinct identification of keratin pearls and individual cell keratinisation in OSCC-modified PAP stain is better. It can be used as alternative stain to H&E for histological grading of OSCC based on keratinisation.
期刊介绍：
The journal of Oral and Maxillofacial Pathology [ISSN:print-(0973-029X, online-1998-393X)] is a tri-annual journal published on behalf of “The Indian Association of Oral and Maxillofacial Pathologists” (IAOMP). The publication of JOMFP was started in the year 1993. The journal publishes papers on a wide spectrum of topics associated with the scope of Oral and Maxillofacial Pathology, also, ensuring scientific merit and quality. It is a comprehensive reading material for the professionals who want to upgrade their diagnostic skills in Oral Diseases; allows exposure to newer topics and methods of research in the Oral-facial Tissues and Pathology. New features allow an open minded thinking and approach to various pathologies. It also encourages authors to showcase quality work done by them and to compile relevant cases which are diagnostically challenging. The Journal takes pride in maintaining the quality of articles and photomicrographs.
