Argon laser treatment of lentigo maligna.
A 64-year-old man had an irregularly pigmented lentigo maligna over the bridge of his nose. Melanin readily absorbs argon light, and the superficial location of this pool of epidermal and appendageal chromophore suggested that laser therapy might permit relatively selective lesion destruction. Argon laser surgery was performed on Nov. 9, 1981, and the treated site had remained clear to the time of writing. Selected patients with pigmented lesions may respond well to argon laser radiation, but close posttreatment clinical and histologic assessment is essential.
