My 3 yr old son has a small red flat dot above his lip. It has no drainage or swelling, and has remained the same size (like a pinprick). It doesn t go away. I have tried OTC cortisone and neosporin. If I put vasoline, it looks better but doesn t completely go away. It is a perfect circle and flat. He recently went through a round of antibiotics for an infection and the dot remained. It doesn t hurt him but my pedi and I don t know what it is. He has no significant medical history. I am looking for a pedi-dermatologist in my area. My pedi doesn t believe it s anything to be concerned about. My son does have sensitive skin and a hx of eczema - last bout was 2 yrs ago. He tends to wipe his and rub his mouth a lot.
