- Abstract
Peutz–Jeghers syndrome (PJS) is a rare genetic disorder characterized by multiple gastrointestinal polyps and mucocutaneous pigmentation. Abnormal pigmentation typically develops in infancy or childhood. As PJS-related facial pigmentation can lead to psychological burden due to its effects on esthetics, treatment is required. Herein, we report on the efficacy and safety of treatment of lip mucosal pigmentation using a Q-switched 755 nm Alexandrite Laser in children with PJS, aged 2–12 years of age. A topical anesthetic was used prior to the application of laser therapy. A treatment efficacy of 100% was achieved with one to three treatments, with an excellent outcome achieved in five cases (62.5%) and a good outcome in three (37.5%). Recurrent pigmentation was observed in one case over the 6-month follow-up period. There were no adverse effects, such as scarring or hyperpigmentation or hypopigmentation. The treatment did cause pain, apprehension, and crying in some children, requiring special attention. Although our sample size is small, our findings do provide support of the high efficacy and safety of the Q-switched 755 nm Alexandrite Laser for the treatment of lip mucosal pigmentation in children with PJS. Further studies are required to confirm these findings.
