My newborn daughter appears to have a pale and slightly pink, bumpy hairless patch near the crown of her scalp. While in the hospital the Pediatrician didn t mention anything about it so I assumed it was eczema or something of that nature. We had a hospital f/u appointment today with a different Pediatrician who again did not mention anything about it until I brought it up. He basically said not to worry about it and that they ll check it again in 2 weeks; that it may be gone by then. If not, he said it could be a sebaceous nevus, a type of birthmark that had been linked to cancer (although it is not as serious as once was believed). He basically told me not to look it up online because what I would find might scare me. Of course, once you say the word cancer to a new mother you can expect them to do just the opposite for fear of their baby s life. What I found online was alarming...developmental delays, CNS abnormalities and mental retardation. My questions are: What really is sebaceous nevus? How dangerous is it? Are all cases linked to mental retardation, developmental delays, etc? Is there a cure/treatment? Should I be worried and scared or is this something that is harmless and can removed rather easily? With no information given to me, you can imagine the stress I ll endure over the next 2 weeks until we see the doctor again. 4 days post-partum and my emotions are already on overload. Any help/advice would be greatly appreciated. I can email a picture if necessary. Thank you.
