ABSTRACT
BACKGROUND AND OBJECTIVE:
Labial lentigines associated with Peutz-Jeghers syndrome are cosmetically disfiguring and distressful. Although multiple treatment modalities including Q-switched ruby laser and Q-switched alexandrite laser have been proposed, experience with Q-switched NdYAG laser has been lacking. This study aimed to retrospectively evaluate the efficacy and safety of Q-switched NdYAG laser (532 nm) for labial lentigines in Peutz-Jeghers syndrome. PATIENTS ANDMETHODS:
Demographic and clinical data of 11 patients diagnosed with Peutz-Jeghers syndrome were analyzed. A quartile grading system was used. All patients were treated with a Q-switched NdYAG laser system with the following parameters wavelength 532 nm; spot size 3 mm; pulse duration 5-20 ns; fluence 1.8-2.2 J/cm(2) .RESULTS:
After two to six (mean 3.6) treatment sessions, an average grade of 3.73 was achieved. Eight patients (72.7 %) showed an excellent response with more than 75 % lesion clearance. Three patients (27.3 %) showed a good response. Repeated treatments led to improved clearance of labial lentigines. Age, gender, and Fitzpatrick skin type were not statistically associated with efficacy grades after the first treatment session. Neither recurrence in treated areas nor significant complications were observed.CONCLUSIONS:
Q-switched NdYAG laser provides an effective and safe treatment option for labial lentigines associated with Peutz-Jeghers syndrome.
