Dr. Sujay Khandpur and Dr. Vinod K Sharma of the Department of Dermatology and Venereology, All India Institute of Medical Sciences, New Delhi, India have completed another interesting study on the use of the pulsed dye laser (PDL) in treatment of vascular dermatoses.

They have successfully employed PDL to treat several non-vascular conditions in fair skinned individuals without producing significant pigmentary and textural complications. This study was undertaken to assess the efficacy of PD lasers in cosmetically distressing facial, vascular and non-vascular dermatoses in Indian patients with skin types IV and V.

Materials and Methods: Nine patients of ages 7 to 55 years, with facial verruca plana (VP- 4 cases), angiofibromas (AF- 4 cases) and multiple pyogenic granulomas (PG- one case) were recruited. They had no systemic complaints. Laser parameters used were (spot size/fluence/wavelength/pulse duration):VP- 5mm/5.5-7.5J/585nm/0.45ms; AF-5mm/6-8.5J/585nm/0.45ms;PG- 5mm/7J/585 and 595nm alternately/1.5ms. Response was assessed clinically and photographically.

Results and Conclusions: All VP lesions completely resolved after 2-4 sessions (mean 3.25 sessions), AF showed 50% regression in all cases after 2-3 sessions (mean 2.5 sessions) and ≥75% subsidence after 3-7 sessions (mean 5.5 sessions) and in PG, after 3 sessions, there was complete subsidence of small satellite lesions with moderate shrinkage of larger papules and complete resolution after 5 sessions. Complications included transient hyperpigmentation/hypopigmentation only. There was no recurrence during next 6 months. PDL offers significant cosmetic improvement in facial dermatoses in Indian patients.
