Significant improvement of a nevus spilus-type congenital melanocytic nevus with oral selumetinib.

ABSTRACT

Giant congenital melanocytic nevi (GCMN) can be cosmetically significant and can lead to melanoma. There is no standard pharmacologic treatment for GCMN. We present the case of an 8-year-old female with kaposiform lymphangiomatosis caused by an NRAS mutation whose nevus spilus-type GCMN improved on oral selumetinib.
