Abstract
|
|
|
|
Seborrheic keratoses are benign skin lesions, which present clinically as well-demarcated round to oval-shaped tumors. Laser devices used for treatment of seborrheic keratosis include ablative lasers, such as the erbium:YAG laser and carbon dioxide laser, and non-ablative lasers, such as the 532-nm diode laser, 755-nm alexandrite laser, and 532-/1064-nm Nd:YAG laser. Here, we report on a 77-year-old patient with light-browncolored seborrheic keratoses, which was effectively treated using a longpulsed 755-nm alexandrite laser without color enhancement. We suggested that the delivery of long-pulsed high fluence laser energy to seborrheic keratoses with protection of epidermis by an integrated dynamic-cooling device could have provided high efficacy and low risk of side effects even in light-colored lesions with few target pigments.
