title: Angiolymphoid hyperplasia with eosinophilia: good response to photodynamic therapy.
abstract: Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign vascular disease of unknown pathogenesis, that occurs as solitary or multiple nodules or papules. Lesions are located mainly on the head, forehead and neck, and may be persistent and difficult to eradicate. We report a case of ALHE treated with aminolaevulinic acid photodynamic therapy (ALA-PDT). Treatment consisted of two ALA-PDT sessions with a 2-week interval. Clinical evaluation, 8 weeks after treatment, showed marked improvement though not complete regression. The treatment was well tolerated. At follow-up 4 months after treatment, the lesions were stable. We believe that PDT could be an alternative therapeutic approach for ALHE or could be used as a neoadjuvant treatment to reduce lesion size especially where size or site of lesions limits the efficacy or acceptability of other treatments. The lack of cumulative effects allows repeated treatments with ALA-PDT, but long-term follow-up is advised for assessment of recurrence.
