A variation of Mohs' technique, that is, microscopically controlled surgical excision is presented. The use of fresh tissue eliminates the need for zinc chloride paste. This substantially decreases the discomfort of the procedure and shortens the time necessary for extirpation of difficult tumors. A series of 102 basal cell carcinomas occurring in 85 patients was treated by this method. With a minimum follow-up of three years and a maximum of eight years there have been only three recurrences. We believe that this method retains the high cure rate previously experienced with the standard Mohs' technique, but offers important advantages.
