Types of Pigmented Defects

Age spots/lentigines: Flat tan spots due to long-term sun exposure. These may lighten, but do not clear in the absence of sun. They also are called liver or wisdom spots.

Freckles: Flat brown, pigmented spots. These clear totally in the absence of sun.

Melasma: Facial discoloration that is tan in color and is associated with female hormones seen in pregnancy and with taking oral contraceptives.

Seborrheic keratosis: Benign skin growths unrelated to sun exposure that can be flat or raised; colors range from pink to brown.
