My 3.5 yr old son has two random white spots on his body. One is near the pelvis on his upper right thigh, which has been there since he was a baby though not since his birth. It's an irregular shape no more than half an inch across, definitely hypopigmented. The other one I just found on his chest, about the size of a small pea. He is a bir on the ADD side--any cause for concern of Tuberous Sclerosis? Plus, what does a seizure look like in a baby, can it take more than one form?
