Abstract: Background: Ample research is being conducted at present to tackle the global malice of oral squamous cell carcinoma. There is a need to understand the carcinogenetic process by exploring various biological markers and cells involved. Langerhans cells are antigen-presenting cells that are known to have an anti-tumorigenic role while mast cells are an inherent part of inflammatory cascade that lead to microenvironmental conditions favorable for invasion. The present study aims at analyzing the correlation between the two and understanding their role in development of carcinoma. Materials and Methods: Tissue blocks were obtained from the archives of the department consisting of histopathologically confirmed cases of oral squamous cell carcinoma. Two sections were obtained from each specimen, one of which was observed immunohistochemically for CD-1a positive Langerhans cells while the other was observed for mast cells.....
