Abstract
A common but under-recognized complication of Mohs micrographic surgery is the development of surgical site telangiectasias after repair. Treatment with pulsed dye laser has shown good results in treating periscar telangiectasias, while treatment with KTP laser has never been studied for this complication. We report the findings in six patients with persistent telangiectasias post-Mohs micrographic surgery and their response to treatment with KTP laser. After one treatment with KTP laser, the severity of telangiectasias, scar erythema, and patient and physician-rated improvement were recorded. Response to KTP laser was variable. However, this case series suggests that KTP laser may have the potential to improve the appearance of periscar telangiectasia after Mohs micrographic surgery.
