Conversation: The conversation between human and AI assistant.
[|Human|] My 7 year old has what looks like dirt on his neck. It s not, it s just discolored in the creases. He s not overweight in any way. He eats pretty well most days. He s ADHD if that needs to be added. What should I be looking into? What would his doctor test him for? Is this normal in kids or should I be worried?
[|AI|]  Hi... By what you quote I feel that it could be acanthuses Nigerians. But you say he is not obese. Acanthuses Nigerians occurs commonly in obesity. Skin conditions are best diagnosed only after seeing directly. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
