I am 41 years old and my Vitiligo first showed up when I was 5.  I developed a rather large patch on my left leg right away, with only a few smallish patches on other areas of my body.  No real spreading after the first year or so, and I actually had some repigmentation in my teens(no treatment, totally spontaneous)  Fast-forward to age 38, after I had my first and only child.  Vit went CRAZY soon after I gave birth.  I also had major post-partum depression and anxiety(my stress level was OFF THE CHARTS).  Large new areas on my knuckles, back of one forearm, tops of feet.  Very discouraging considering I'd spent MANY years thinking it probably wouldn't spread anymore.  No one has Vitiligo in my family, but my father did have age-onset Diabetes, my grandmother had prenicious anemia, and my sister (2 1/2 years older) has thyroid issues.
