RESUMO
Cryosurgery is a commonly used modality for treatment of benign and malignant lesions in dermatology. Although cryosurgery has been used for treatment of actinic keratoses, to our knowledge there have been no published reports on actual cure rates. This article presents a cryosurgical technic for treatment of actinic keratoses and the cure rates of 1,018 lesions with a follow-up of at least 1 year.

Chromoblastomycosis was successfully treated by cryosurgery in a 55-year-old white man. Depigmentation within the scar precludes an entirely successful cosmetic result.

The Foster "Froster" unit is a new and simplified liquid nitrogen system for use in dermatologic cryosurgery. The details of its operation are described and its use in various benign, premalignant, and malignant lesions is discussed. In malignant lesions, not only type, but frequently location, is important when deciding whether to use cryosurgery as the first, alternate, or adjunctive choice of therapy. Benign and premalignant lesions which respond best are sebaceous hyperplasia, dermatofibromas, actinic keratoses, leukoplakias, lentigines, and certain seborrheic keratoses and verrucae. Initial promising results have been reported in cases of swimming pool granuloma and chromoblastomycosis. Application of the described technics in one's clinical practice must depend primarily on the level of knowledge of skin lesions and on the degree of skill attained in cryosurgical methods.

The authors report in detail the development of a simplified, yet highly efficient cryosurgical instrument. It is lightweight, portable, inexpensive, and easy to use. Studies show it to be comparable in most instances to a popular contemporary unit. Its chief drawback appears to be that it cannot serve as a liquid nitrogen reservoir for extended periods, although it can be used for multiple procedures without re-filling.
