Symptomatic dermatographism treated with narrowband UVB phototherapy

摘要

Dermatographism occurs when there is an exaggerated response to physical stimulus. There are both simple and symptomatic forms. Symptomatic dermatographsim can be exceedingly difficult to treat. Treatment modalities include H1 and H2 antagonists, leukotriene antagonists, cyclosporine and oral steroids. In a few small case series and studies, phototherapy has been used. We report a further two patients who were treated successfully with TL01 UVB narrowband (NB) phototherapy.
