Nevus anemicus in Child
Nevus anemicus may also occur in association with several syndromes, including neurofibromatosis (up to 4% of cases) and phakomatosis pigmentovascularis (PPV), a syndrome consisting of combinations of cutaneous and vascular findings that may include capillary malformations, dermal melanocytosis, and nevus spilus, caused by mutations in the GNAQ / GNA11 pathways. Nevus anemicus has also been seen in patients with Legius syndrome with confirmed SPRED1 mutation and Noonan syndrome with lentigines, with a confirmed PTPN11 mutation.
