    Abstract:
    BACKGROUND: Verrucae vulgaris can be removed in a variety of ways but a specific therapy of choice has not yet been developed. Doctors are faced with a challenge, especially in the treatment of recalcitrant warts. It has been suggested that the success of pulsed dye laser treatment lies in the fact that warts contain an increased number of dilated blood vessels. METHODS: Seventy-three patients (42 female, 31 male) with verrucae vulgaris on their hands or feet (1:1.5) were given a maximum of 12 treatments with a flashlamp-pumped pulsed dye laser every 2 weeks over a period of 24 weeks until complete clearance had been achieved. A laser energy density of 8 to 12 J/cm2 with a spot size of 5 mm and a pulse duration of 450 microsec were used. The minimum follow-up period was 6 months. RESULTS: A total of 15.1% patients achieved complete clearance after 1 session and 47.9% after 2 to 5 sessions, resulting in a remission of 63.0% patients after a maximum of 5 treatment sessions. A remission of 23.3% patients was seen after 6 to 9 treatments and a total of 89.0% of patients showed remission after a maximum of 10 sessions. Only three patients (4.1%) failed and five patients (6.9%) stopped the treatment on account of pain/noncompliance. Only one patient, from a group of patients treated between January 2003 and April 2004, has relapsed. CONCLUSION: Pulsed dye laser treatment is effective and safe in the treatment of recalcitrant viral warts.
