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. 

Macules may develop as a result of [[cystic acne|cystic]] or otherwise severe [[acne]]. They occur after a pimple or cyst has healed, and may remain for up to six months. They are sometimes known in such cases as "pseudo-scars", but unlike true scars they are not permanent.
