Macules
The macule is the simplest dermatological lesion. It is flat and can only be seen and not felt. The macule is noted by a change in color of the skin. It may be brown, blue, red or exhibit a lesser pigment or an absence of pigment. The color of the lesion is one way in which a diagnosis may be focused.
