A foreign growth on the skin can discolor skin or a change in your body's production of melanin.Skin patch discoloration could also be a symptom of a medical condition. If they worry you, get your doctor's opinion.

One disease that I can think of that causes discoloration of the skin is Vitaligo. My family members have been diagnosed with this, and it is nothing serious. This is the disease that Michael Jackson supposedly had.
