To the Editor.—
There have been few reports in the literature of complications from the use of cryosurgery in the treatment of benign and malignant skin lesions. We would like to report the development of a pyogenic granuloma in an area treated by cryosurgery for a basal cell carcinoma.
Report of a Case.—
A 64-year-old man was referred to the Dermatology Clinic, University of Virginia Hospital, in November 1974, for evaluation of a lesion in the lower midback area that had been present for at least two years.

After insertion of two thermocouple needles approximately 5 mm beneath the surface of the carcinoma, the lesion was treated by cryosurgery. Within 60 seconds of freezing, the thermocouple needles
