<s>[INST] My 14 month old has a bump on her labia. It started out looking like a mosquito bite and then had a yellow ulcer type look to it. Or similar if you scratch yourself and then ahve the film of yellow over it. (not a blister type) It doesnt seem to hurt her when I touch it or put vasealine on it during diaper change. It is now looking as if it is going to scap over. It doest apprear to itch either, like I said it doesnt bother her it seems. What could it be? [/INST] Hi...by what you quote I feel that it could, be a pyoderma or skin infection which is scabbing over. But skin conditions are best diagnosed after directly seeing them. I suggest wither you upload a photograph in this website or get the consultation of a pediatric dermatologist.Regards - Dr. Sumanth </s>
