It consists of taking a sample of skin by different methods and sending it to be reviewed by a pathologist or dermatopathologist (thank you for existing)
Who will make cuts (millimeter slices of the skin), put special dyes and see it under the microscope, then will make a report of what can be observed in each skin layer
The decision to take it or not, the site and the method will be preferentially guided by the dermatologist who is assessing you
