Synopsis

Nevus anemicus is a cutaneous finding characterized by well-defined, hypopigmented macules coalescing into larger irregular patches due to congenital local hypersensitivity of cutaneous blood vessels to catecholamines. This results in persistent vasoconstriction and subsequent pallor of the affected skin. Nevus anemicus is most commonly found on the trunk, but may be found on the face and extremities as well. It is usually first noticed at birth or in early childhood, but because it can often be subtle and is asymptomatic, it is frequently an isolated incidental finding. Nevus anemicus may also occur in association with several syndromes, including neurofibromatosis and phakomatosis pigmentovascularis, a syndrome consisting of combinations of cutaneous and vascular findings that may include capillary malformations, Mongolian spots, and nevus spilus.
