Objective To describe the epidemiological data of the microsurgical treatment of peripheral nerve tumors performed by the Brazilian Unified Health System (SUS, in the Portuguese acronym), with the code 0403020131, from 2008 to 2016, regarding the number of annual procedures, hospital and professional expenses, the average duration of hospital stay, and the number of deaths. Methods This is a descriptive epidemiological study whose data were obtained by consulting the database provided by the Health Informatics Department of the Brazilian Ministry of Health (DATASUS, in the Portuguese acronym). Results/Discussion A total of 6,012 procedures were performed during the period studied, with an average of 688 procedures per year. The average hospital stay was of 2.13 days. There was nomortality rate. The average annual cost of the professional was BRL 50,091.45; and the average hospital expenses were BRL111,887.94. Conclusion The microsurgical treatment of peripheral nerve tumors is a safe surgical procedure with zero mortality rate and short hospital stay. There was no national data on tumors of this nature in the medical literature.
