Photobiomodulation Therapy for Multiple Painful Fixed Drug Eruptions: The First Case Report.

Fixed drug eruption (FDE), a very specific adverse drug reaction and one of the most common types of drug eruption, generally resolves spontaneously within 7-10 days upon withdrawal of the causative agent; however, extensive and severe cases may also require systemic drug therapy. The present study aimed to report a case in which a broad spectrum of severe, painful lesions of FDE was managed with photobiomodulation therapy (PBMT). A 31-year-old Caucasian woman presented with many extremely painful mucocutaneous lesions of FDE which had arisen 8 days before, following a long period of hospitalization.
