See Disclaimer regarding information on this site. Some links on this page may take you to organizations outside of the National Institutes of Health.

Overview


Nevus of Ito is a colored birth mark that is usually slate-brown or blue/gray. It is an unusual birthmark in which the melanocytes (pigment cells) are found deeper than normal in the skin. This type of birthmark is usually located on the shoulder and upper arm area on one side of the body. It can sometimes be associated with sensory changes in the involved skin area. Very rarely does nevus of Ito become cancerous. The exact cause is unknown. They are most commonly found in Asian populations and appear more frequently in females. They are very uncommon in Caucasians.[1][2]
