My 3 year old has strange bumps/nodules on his chest, stomach area. When they first appeared, my husband and I thought it was just raised moles, as my husband has a few of them. My son has had them for approximately 6 months. But just recently, the largest became red around the base and then turned completely white and looked as if it would burst. My husband pinched the skin around the largest lump slightly to examine it better and firmer, white stuff popped out of it, similar to a zit. He repeated the same step on another and the same thing happened. It looks as if the condition is spreading, as we found another one on the inside of his arm and more have appeared on his stomach. My son says they don't hurt at all. We considered a boil or something, but they have lasted a long time and seem to be spreading like it's contageous. We also thought it may be warts, but they are more soft and rubbery like moles. Plus with the recent white debris coming out, we figured it wasn't warts.
We plan on taking him to see his pediatrician next week. But any ideas about what this could be and is this something that needs more immediate attention?
