Aminoleveulinate photodynamic therapy (ALA-PDT) for Bowen's disease in a SLE patient: Case report and literature review

We reported a rare case of topical 5-aminolevulinic acid (ALA)-photodynamic therapy (PDT) in the treatment of a systemic lupus erythematosus (SLE) patient with lower limb multiple Bowen's disease (BD). At the end of the treatment, an excellent clinical response was observed and no recurrence of rash after 2 months of treatment. The recovery time was prolonged only after the first treatment, however, no photosensitive phenomena were observed during and after the treatment. This is the first report to describe ALA-PDT for patient-confirmed photosensitivity in an Asian patient. Whether PDT is contraindicated for SLE remains to be discussed, although our findings show that PDT can be used as an alternative therapy for SLE patients with BD who cannot tolerate surgery.
