My 2 year old was born with this same bump. I took him into his pediatrician and was referred to Children's Hospital for a 2nd opinion. After evaluating him, the specialist explained that it was common and called a water cyst. It was simply explained as a "water pouch" which is found under the skin. The doctor explained that they could extract it once my son aged. He also explained that the water pouch could be drained out with a syringe but that the pouch would just create more water. So the best option would be to remove the whole pouch by having a small incision made once he became older or if the pouch became bigger. He explained this bump didn't cause him pain. And sure enough it didn't. Well my son is about to turn 2 years old and I am happy to say that the bump disappeared on its own! Just make sure to keep your eye on it.View Thread
