Q-switched alexandrite laser therapy for pigmentation of the lips owing to Laugier-Hunziker syndrome.
BACKGROUND
Laugier-Hunziker (LH) syndrome is a rare benign condition in which hyperpigmentation of the lips and buccal mucosa occurs with no systemic associations.


OBJECTIVE
We report the response to treatment with the Q-switched alexandrite laser (QSAL) because there are few reports on therapy for LH syndrome.


METHODS
The QSAL was used for pigmentation of the lips in a 63-year-old woman with LH syndrome. Laser irradiation was done at 5.0 J/cm2 with a 3 mm spot size.


RESULTS
There was 100% clearance of pigmentation of the lips with a single laser treatment, and recurrence was not observed after 6 months.


CONCLUSIONS
The QSAL is very effective for pigmentation owing to LH syndrome.
