595-nm long pulsed dye laser and 1450-nm diode laser in combination with intralesional triamcinolone/5-fluorouracil for hypertrophic scarring following a phenol peel.

Overview

Hypertrophic scars and keloids are a therapeutic challenge because of the low response to treatment and recurrences after treatment. A variety of treatment regimens have been used with different degrees of success, with no universally accepted treatment protocol resulting in their complete and permanent resolution. We offer this case to demonstrate a combination approach for the treatment of hypertrophic scarring. A 75-year-old woman (with Fitzpatrick skin type II) presented with a 4-month history of scarring, which had developed following a phenol peel for perioral rhytides. The patient underwent 10 treatment sessions with the 595-nm long-pulsed dye laser followed immediately by the 1450-nm diode laser in combination with intralesional triamcinolone and 5-fluorouracil. After the fifth treatment session, about 90% improvement was noted; at the last treatment session, greater than 95% overall improvement was noted. Two and a half years after the last treatment session, the patient and treating physician noted no regression. A limitation of this therapy is that the combination approach makes it difficult to determine what individual contributions each treatment modality had on the final result. We have illustrated a successful multifaceted treatment regimen for hypertrophic scars and keloids using a combination approach.
