café au lait spots
pigmented cutaneous lesions, ranging from light to dark brown, and due to an excess of melanosomes in the malpighian cells, rather than to an excess of melanocytes; café au lait spots are one of the major cutaneous manifestations of neurofibromatosis (von Recklinghausen disease); six or more café au lait spots, some exceeding 1.5 cm in diameter, can almost always be found in type 1 (peripheral) neurofibromatosis. These are often accompanied by frecklelike spots in the axilla.
