chloasma
(klō-ăz′mă )

[Gr. chloazein, to be green]
Tan to brown, sharply defined patches of skin pigment, usually found symmetrically on the forehead, temples, cheeks, or upper lip. The excess pigmentation often occurs in pregnant women, in women using oral contraceptives, or in patients with underlying liver disease. Women are affected more often than men. Sun exposure tends to worsen the condition.
