[|Human|] Phi,Hello, I am visiting my friends home in rural Alabama. Their daughter, age 16 years old, said she had a rash on her neck. She has perfectly round dark circular spots on the nape of her neck. They almost look as if the spots tanned and nothing else did.  Her skin is smooth and that area does not itch.  She does not spend much time outside and has fair skin. Other than moderate acne, she has no other symptoms.  What do you think it could be?
[|AI|]  Hi. Your friends' daughter seems to have Tina tricolor. It is fungal Infection. It is caused by Melanesia fur fur. It may be increased by perspiration. The fungus resides on scalp. Tell her to Apply ketoconazole cream. And shampoo with ketoconazole lotion. And to take ketoconazole tablet for 3 to 4 weeks. She should take healthy food to improve immunity. Tell her to avoid soap bath. I feel, She will be improved. I hope you got my answer. Thanks.
