Cryosurgery is an alternative treatment option to surgical excision for len
tigo maligna. Clinical evidence of recurrence is usually characterized by r
epigmentation at the treated site. We report two patients who developed ame
lanotic malignant melanoma following cryosurgery for a pigmented lentigo ma
ligna. These cases illustrate the potential risk of treating lentigo malign
a with cryosurgery.
