To analyze the clinicopathological profile of young patients (<= 40 years) with oral SCC and correlate with a control group (>= 50 years) by means of histopathological grading systems. 14 young patients and 14 control patients were selected with similar clinical stage and tumor location. Demographic and clinical data were obtained from patient records and histological sections were evaluated according to four histopathological grading systems. Associations between categories of demographic and clinical data were performed through Chi-square test and Exact Fisher test. The survival analyzes were performed according to the Kaplan-Meier method. The comparison between groups showed a greater association of treatment modalities in younger patients (p=0.022), they had a higher incidence of local recurrence and regional metastasis (p=0.018) and lower disease-free survival in 5 years (p=0.069). There was no difference in 5-year overall survival among the studied groups. There was no difference in histological grading between studied groups according to the four used systems. This study showed that, despite tumors had similar histological grade and more therapeutic modalities were used in the young group, tumors in young patients had a higher incidence of recurrence/metastasis, showing tendency to a more aggressive behavior
