Continued sun protection and continued observation for the prevention of actinic keratoses and malignant neoplasms are needed.The first laser test treatment for this condition was given more than ten years ago. Two impacts of ruby laser with an energy density of 60 joules/sq cm with a target area of 2.1 sq cm were administered. After the initial crusting subsided, a soft white area, 2.1 sq cm, developed and remained white, without revascularization, for months. The patient did notThree weeks after argon laser surgery with the patient under general anesthesia; 5-mm probe; 2 W; 379.8 s; irradiance, 10 W/cm; energy fluence, 3,798 joules/cm. return for continued observation and therapy.Recently, another patient with an extensive postsolar poikiloderma of the neck requested a laser test treatment.
