Just found this thread a couple of weeks down the track, and thought I'd tell you that though my DD doesn't have a hemangioma, I certainly did have two of them when I was born. One was a whopper- about 4cm across- over the left side of my forehead (just above the hairline, though I didn't grown much hair to cover it for a couple of years!). The other was about the diameter of a 20c piece, but it was across my left eye/ eyebrow, so it couldn't have been much more obvious. Both were the bright red strawberry colour.

I'm 28 now and I don't have a mark on me Both had faded completely by the time I was about two years of age, with no treatment. The larger one on my head sank and a couple of times when I was younger I bumped it hard enough to make it bleed profusely, but I haven't had that problem for years.

I'm sure your DS will lose his with time too, especially if he gets a bit of treatment for it. Good luck!
