senile lentigo (lentigo seni´lis,) (solar lentigo) a small smooth round brownish patch appearing on the face, neck, or back of the hands of many older people, caused by an increase in pigment; these are entirely harmless. Although these spots are associated with aging, it is not age that is the principal cause but many years of exposure to sun and wind. Called also liver spot.
