fading skin coloring. See Arabian fading syndrome (below). Declining in body condition, general health, activity and productivity.

Arabian fading syndrome
general health is unimpaired. Affected horses, usually Arabians, gradually lose their skin coloring on round, depigmented macules and multiple patches, most obviously around the muzzle and the perineum. It is a noninflammatory leukoderma. The cause is unknown. See also vitiligo. Called also pinky syndrome, lavender foal.
