Background:

Epidemiological data on the clinical presentation of high-grade primary tumors, the most common histological variables and prevalence, and sociodemographic variables were addressed from January 2016 to December 2020.

Method:

The sample was calculated from the primary tumors provided by the statistics department, determined the ICD-10 (C-71), finding 105.

Results:

The frontal lobe was the most common location, consultation times lasted between 3-6 months, the most common clinical symptom was headache; the most common reason for consultation were seizures.
