Background and aims: Molluscum contagiosum is caused by the molluscum contagiosum virus (MCV) and is a very common skin disorder mainly involving young children Cryotherapy, curettage or some topical therapies have been applied for MC, but all of these treatments need several sessions, can be somewhat ineffective, and very painful. The present study assessed the impact of a single session of pulsed dye laser treatment of MC lesions which had proved resistant to other approaches
Subjects and methods: Fifteen children comprised the study subjects, 11 boys and 4 girls, 3-5 years of age (mean 4.2 yr) with recalcitrant MC. Lesions were counted at baseline, and a single shot from a 585 nm pulsed dye laser was applied to each lesion (3 mm, 300 ms, 8.0 J/cm2). Lesions were counted again at 1 week post-treatment and followed for up to 3 months thereafter.
Results: All patients completed the study and no patient dropped out through pain or discomfort. Purpura was seen at each treated lesion immediately after irradiation, but at 1 week after treatment, lesion clearance was virtually complete which was maintained for 1 month, and no recurrence was seen at 3 months in 8 of the 15 patients who remained available for followup.
Conclusions: A single treatment of MC lesions with the pulsed dye laser successfully cured even recalcitrant lesions with no recurrence on follow up, and was well tolerated by the young subjects.
