Aminolevulinic Acid Photodynamic Therapy in the Treatment of Erosive Pustular Dermatosis of the Scalp: A Case Series.
JAMA Dermatology 2016 June 2
IMPORTANCE: Erosive pustular dermatosis of the scalp (EPDS) is an inflammatory skin condition that develops on sun-damaged skin in older individuals. Patients with EPDS present a therapeutic challenge because medical treatments and surgical modalities have met with limited success. Methyl aminolevulinate photodynamic therapy has been effective in 1 case but induced the disease in others.
OBSERVATIONS: Eight patients with EPDS with mean (range) age 84 (67-93) years underwent gentle curettage of the hyperkeratotic lesions followed by aminolevulinic acid photodynamic therapy (PDT) 1 to 2 weeks later. Lesions resolved in 6 patients, whereas 2 patients had residual lesions at 6-week follow-up and underwent a second cycle of curettage and aminolevulinic acid PDT with resolution. One patient experienced a partial recurrence 5 months after the procedure and was successfully retreated with curettage + aminolevulinic acid PDT. No adverse effects were noted, and patients were satisfied with the treatment.
CONCLUSIONS AND RELEVANCE: This series of patients demonstrated EPDS successfully treated with PDT. Lesions resolved in all patients with a protocol that included curettage followed by aminolevulinic acid PDT. Therefore, this protocol represents an efficacious modality for EPDS.
