Abstract
Background and aims: Oral mucosa is prone to various lesions. Some of these lesions can be early signs of a particular disease or even malignancy in the body. The aim of this study was to investigate the frequency distribution of oral biopsies from 2009 to 2019.
Methods: In this analytical descriptive cross-sectional study, 621 records of the oral cavity biopsies performed in the pathology department of Shahid Sadoughi hospital were analyzed. Age, gender, type of lesion, site of lesion, histopathological diagnosis, year of referral, and medical specialist who performed the biopsy were included in the study checklist. The data were analyzed using chi-square and Kruskal-Wallis test in SPSS version 25.0.
Results: Of 621 biopsies, 308 specimens belonged to men (49.6%) and 313 specimens belonged to women (50.4%). The mean age of patients was 46.58±21.08 years, ranging from 6 months to 95 years. The most affected areas were the tongue (33%), lower lip (29.1%) and cheeks (17.7%). squamous cell carcinoma (SCC) (27.9%), inflammatory lesions (26.1%), mucocele (14.8%), and ulcers (8.5%) were the most frequent lesions. There was a significant difference in the age of individuals with different lesions (P<0.001).
Conclusion: The most frequent lesion diagnosed in biopsies was SCC. The most frequently affected sites were tongue and cheek. Lesions were more frequent in women and were most frequently seen in the fourth, fifth, and sixth decades of life.
