Synopsis
Melasma is characterized by irregularly bordered, evenly pigmented tan macules on the face. Darker macules may sometimes be seen ("dermal melasma"). Although the pathophysiology of melasma is poorly understood, thyroid autoimmunity, ultraviolet radiation, hyperestrogenism (pregnancy, contraception), genetics, and anti-epileptic medications are known to be contributing factors.
