Background: To study the demographics and histopathological patterns of oral squamous cell carcinoma (OSCC) reported at a tertiary level referral teaching hospital in Hyderabad, India. Materials and methods: An institutional retrospective study of biopsies sent to a tertiary level referral teaching hospital, Hyderabad.

Results: A total of 1,005 oral biopsies were reviewed. Of these, OSCC was seen in 234 cases (23.28%). Buccal mucosa (47.7%) was the most frequently involved site followed by tongue (27.6%). Most of the OSCC patients were in the age group of 41 to 50 years, males and histopathologically well-differentiated (62%). Conclusion: This study showed that OSCC is widespread in the patients of this region.
