[|Human|] I have a rash on my buttocks that may have been acquired from an infected toilet seat;  I have applied anti-fungalcream, cortizon cream, Vitamin A& D ointment;  they appear to help in that the scaling goes a way, itchynessgoes away, but discoloration of skin remaines.  However, these creams unfortunately do not clear the rashcompletely.  Once I stop application, rash is there with discoloration of skin; the itch returns and scaling setsin once again.  What do you think might be going on?
[|AI|]  Hi, thanks for your query. It seems you have a fungal infection on your buttocks. For this you need to take oral antifungal medicine by prescription along with local application of antifungal creams. Don't scratch the lesions instead take oral antihistamines for itching. Avoid applying cortisone cream as infection may flare up with a steroid. You may apply vitamin A&D ointment. I suggest you to meet a dermatologist for exact diagnosis and treatment. Hope this helps you.
