Abstract
Background: In oral carcinoma much effort has been made to predict the prognosis of patients but a sound understanding of underlying cell biology is likely to need progress. Recently, attention has been directed towards tumour associated tissue eosinophils and mast cells and their role in the biologic behavior of tumours. Aim: The retrospective study was used to evaluate the influence of tumour associated tissue eosinophils and mast cells on prognosis of oral squamous cell carcinoma (OSCC). Material and methods: The follow-up, of histopathologically diagnosed thirty cases of OSCC, was carried out for minimum period of 3 years. Special stains are wonderful they allow us to see which we can not see clear with routine H&E stain.Tissue sections were stained with special stains, Carbol Chromotrope for tissue eosinophil and Toluidine blue for tissue mast cell staining. Result: The results of the present study shows that increase infiltration of tissue eosinophils and mast cells in OSCC, associated with favourable prognosis. Conclusion: We concludes that infiltration of tissue eosinophils and mast cells are indicators of favourable prognosis in OSCC. Thus quantitative assessment of eosinophils and mast cells are the most important aspects of the microscopic evaluation of OSCC.
