Abstract

BACKGROUND AND OBJECTIVES:

Both the diagnosis and the treatment of lichenoid dermatosis are often difficult and can be time-consuming. There are now more and more publications about the use of laser systems--especially the flashlamp-pumped pulsed dye laser--in the treatment of inflammatory dermatoses, although the laser's exact mechanism of action in these cases is not yet clear.

STUDY DESIGN/PATIENTS AND METHODS:

We report on a female patient with lichenoid dermatitis that was presumably drug-induced (roxatidine, H(2) receptor antagonists). After a 10-month treatment with local corticosteroids, without significant clearance the drug was discontinued and the pulsed dye laser was used (wavelength 585 nm, pulse duration 450 microseconds).

RESULTS:

Six laser treatments resulted in complete clearance of the lesions. No recurrence occurred during the follow-up period of 54 months. Scars were not observed. A post-operative biopsy showed no evidence of lichenoid dermatitis.

CONCLUSIONS:

The pulsed dye laser seems to accelerate the clearance of presumably drug induced corticosteroid-resistant lichenoid dermatoses. No permanent pigmental changes or scarring were observed.
