Normal-mode ruby laser therapy effectively treated congenital nevi, significantly reducing pigmented lesions with good cosmetic outcomes and minimal scarring in three patients. Further study is needed to determine recurrence risk.

Area of Science:

  • Dermatology
  • Laser Medicine
  • Aesthetic Surgery

Background:

  • Q-switched laser therapy is established for pigmented lesions.
  • Limited data exists on laser treatment for congenital nevi.
  • This study investigates normal-mode ruby laser efficacy for congenital nevi.

Observation:

  • Three patients with congenital nevi received normal-mode ruby laser treatment.
  • Treatments were administered at 1-4 month intervals.
  • Laser parameters: 0.3-1.0 x 10(-3)s pulse duration, 10-30 J/cm2 fluence, 10x10 or 15x15 mm spot size.

Findings:

  • Significant reduction of pigmented lesions to near-normal skin level after four treatments.
  • Excellent cosmetic results with minimal scarring and preserved skin texture.

  • Reduced unsightly hair growth in treated areas.

    • Implications:

    • Normal-mode ruby laser therapy is a viable option for treating congenital nevi.
    • The treatment offers good cosmetic results and potential hair reduction.
    • Long-term recurrence data is pending, though no recurrences were observed in the study period.
