“A HISTOPATHOLOGICAL STUDY OF TUMORS OF ORAL CAVITY”

Abstract

Background: The incidence of oral cavity neoplasms in the population has increased manifold over the years. Oral cancer is one of the common cancers in the world, common in India, and also in Bangladesh, Srilanka and Pakistan. Oral cancer is one of the few cancers, whose cause were known and hence it is possible to prevent. The real challenge in oral cancer lies in its prevention and early diagnosis. Objectives: 1.To study the morphological spectrum of neoplasms in oral cavity. 2.To study the age and gender incidence of various neoplasms. 3.To study the commonest sites of various neoplasms. 4.To evaluate or analyse the associated risk factors. Materials and methods: This is a prospective study of the cases attended to Government General Hospital, Vijayawada or Government Dental College Hospital Vijayawada, of oral cavity neoplasms. The biopsy of the tissues was carried out at the Department of Pathology, Siddhartha Medical College, Vijayawada. The study period was from June 2011 to August 2013 over a period of two years and three months. Results: The Study comprises a total of 74 surgical biopsies from oral cavity neoplasms received in the Department of Pathology, 52 of these were malignant lesions and 20 were benign tumour and 2 were premalignant conditions. The invasive squamous cell carcinoma was the most frequent histological type of oral cavity neoplasms. Among the oral cancers, peak age th th incidence was the 5 and 6 decade of life. There was signicant male preponderance. Tongue was the most common site involved. Smokeless tobacco consumption was the commonest associated habit which leads to malignancy. Conclusion:In thisa study we observed that among the oral cavity neoplasms, high incidence of carcinomas are seen, among these squamous cell carcinomas are predominant.
