Data Sources: Data search was carried out in data base systems of CAB and MEDLINE over a 30-year term. Data Synthesis: Cryosurgery consists of the treatment of lesions through freezing (liquid nitrogen at -196° C).It has been used in medicine for the treatment of skin, liver, kidneys, prostate and oral cavity neoplasias. In. veterinary medicine it is still not broadly known and literature lacks information as to its application. It is an easily performed procedure, requiring however knowledge of the technique, of indications and possible complications and after-effects.
