café au lait spot A flat spot on the skin that has a color similar to that of coffee with milk (café au lait) in persons with light skin or that has a darker appearance than the surrounding skin in persons with dark skin. About 10 percent of the general population has café au lait spots, which can be removed with a Yag laser technique. Café au lait spots are normally harmless, but in some cases they are a sign of neurofibromatosis. The presence of six or more café au lait spots, each of which is 1.5 cm or more in diameter, is diagnostic of neurofibromatosis. See also neurofibromatosis; Yag laser surgery.
