Photodynamic Therapy in Bowen Disease of the First Web Space of the Hand

ABSTRACT

Bowen disease (BD), or intraepithelial squamous cell carcinoma (SCC), may progress to an invasive SCC. Although surgery is preferred because of the low recurrence rate, it can result in hypertrophic scarringor contracture, particularly in lesions on the hands. We report a case of BD in the first web space of the hand, which was treated with ablative fractional laser-assisted photodynamic therapy (AFXL-assisted PDT). After multiple AFXL-assisted PDT sessions, the lesion showed no clinical or pathological abnormalities. Thus, we believe that PDT can be an alternative treatment for BD occurring in the web space of the hand.
