[3 min read] Long-term outcomes of laser for congenital melanocytic naevi
What are the long-term outcomes of laser treatment for congenital melanocytic naevi? Although various laser treatments have been tried for congenital melanocytic naevi, only small retrospective studies with short-term follow-up have been performed to assess outcomes.
A study published in the Journal of the American Academy of Dermatology analysed the long-term outcomes of laser treatment for congenital melanocytic naevi and compared these outcomes with those of a combination treatment including partial excision and lasers.
In the study, patients with congenital melanocytic naevi treated with lasers were retrospectively reviewed, and patients with three or more years of follow-up were categorised as the long-term follow-up group. A total of 67 cases of congenital melanocytic naevi were reviewed.
Among 20 patients with near total clearance during laser-only treatment, 11 patients were in the long-term follow-up group, and five of 11 showed repigmentation. In total, 15 patients showed repigmentation regardless of clearance, and the average period until repigmentation was 3.93 years from the initial treatment.
Patients with partial excision and laser combination treatment showed higher Investigator’s Global Assessment scores, fewer laser treatments, and shorter treatment periods compared with patients with laser-only treatment.
The study concluded that more than four years of follow-up is required to evaluate the efficacy of lasers in congenital melanocytic naevi, and partial excision and laser combination treatment might be an effective treatment option.
