Abstract

AbstractThe use of liquid nitrogen therapy by spray, probe, and direct applicatio in benign skin conditoins is described. Most dermatofibromas do not require treatment, but for avrious reasons some are objectionable to the patient. Forty-five dermatofibromas were terated by cryospray, with five receiving a second treatment. Diagnsis was made clinically and confirmed in ten cases by shave bisy of the elevated portion of the fibroma immediately afte rthawing. In all cases the resulting scar was minimal but sometimes hypopigmented. There was one depressed scar but ont hypertrophic scars. Four mucous cysts of the lip were treated successfully by the cryoprobe without any visible or palpable scar. There was one recurrence. We know of no previous reports ocf cryosurgical treatment of mucous cysts of the lip.
