A PRELIMINARY report on a method of treatment for plantar warts by electrosurgical removal was published in 1942.1 It covered observations for only 21 patients. Since that time I have treated 106 additional patients with the same method; therefore, the conclusion drawn in the preliminary report can be considered now as well established.
The high frequency cutting current is used as a means to destroy the plantar wart, and the source of the current should be a long wave diathermy machine capable of producing a cutting current of the necessary quality and quantity. Short wave diathermy machines are not generally satisfactory for the purpose. There are two principal reasons for this:
1. Because of the extremely short wavelength, standing waves are produced on the electrode, as a result of which a machine which may have been properly calibrated on tissue specimens no longer holds its calibration when applied
