Hence, the present study is carried out to evaluate the histopathological features of OSCC patients to contribute to local and national knowledge. A retrospective observational study was conducted on a convenience sample (n=33) from health care institutions of Seventh and Eighth Chilean regions. The mean age of patients was 65 years.

In these Chilean regions, OSCC mainly affects older people and is located in an easily accessible area for anatomical examination, which should allow early diagnosis.
