The data gathered was entered into Microsoft Excel spreadsheets and transferred to a statistical software program for analysis.Results: 362 cases of oral and para-oral lymphomas were found which constituted 2.86 % of oral and para-oral lesions. The mean age of patients was 54 (standard deviation 18.5), the median age was 56 (age range 3.5-92 years). There was no significant gender predilection.
