Café-au-lait macules (CALM, termed "nevus spilus" in Japan) can be treated using a Q-switched ruby laser (QSRL). However, recurrence is a common problem.
The present retrospective study was undertaken to determine the efficacy of QSRL in 78 patients with CALM. Outcomes were assessed in terms of pigmentation reduction using a subjective grading score that included gender, age at onset, anatomical region of the nevus, and shape of the nevus. Our results suggested that it was possible to predict the response of CALM to QSRL treatment.
A high therapeutic effect of QSRL was obtained for flat nevi with an irregular shape, but CALM with smooth and well-defined borders tended to show a poor response.
