Laugier-Hunziker syndrome: complete clearance of mucosal lentigines with a single session of Q-Switched Nd:YAG laser.

Background

Laugier-Hunziker (LH) syndrome is a rare condition in which melanocyte overactivity produces lentiginous lesions of the lips and buccal mucosa.

Objective

Given the paucity of reports on therapeutic options in LH syndrome, this case is herein reported to show the response to treatment with the Q-Switched Nd:YAG laser in a 32-year-old man with LH Syndrome.

Methods

The Q-Switched Nd:YAG laser was used to treat the lentiginous lesions on the mucosal surface of the lower lips using a single pass at 532 nm.

Results

There was complete clearance of the mucosal lentiginous lesions with a single laser session, and recurrence was not observed after 12 months.

Conclusion

The Q-Switched Nd:YAG laser is an effective treatment option for cosmetic benefit in LH Syndrome.
