My 2 yr old has had a small blister looking bump on her chest for about 2-3 weeks now. It looked as though it was filled with bright red blood, not dark blood like a blood blister. I searched the internet for what it might be. The closest thing I could find was a cherry angioma. The way it felt to my touch was telling me it was filled with fluid, not a blood colored growth. So, today when I came home from work I decided to take a tiny sterile needle left over from a medication I used to have to inject, and I gently poked her blister looking thing. She didn't even notice but blood gushed out the same way the clear fluid from a blister would. It just kept bleeding (no longer gushing) so I put a band-aid on it and let her go play. And now I'm here asking about it. I figure she is fine but what the heck is it?
