Hello and welcome to "Ask a Doctor" service,

I carefully read your query.

There are many causes of an itchy rash on the buttock area ranging from infective causes such as folliculitis or fungal infection to eczema, dermatitis, or heat rash, and in rare cases systemic conditions (conditions that affect other systems but may also cause skin lesions).
It is important for us to have a picture or two of the lesions. Also, it would be helpful if you let us know about the following:
- have you tried any treatment for the rash and how were the results?
- have you had the rash all the time for the last year or it comes and goes?
- is there anything that makes the rash better or worse?
- is the rash raised (bumps) or flat?
- do you have skin problems in other areas of your body?
- do you have any chronic condition or take any medications (prescription or over the counter) regularly?
- do you have any joint pains, fever, or other concerns?
- do you have any specific diet? How are your bowel movements?

Knowing the above information and also examining the rash will help us further determine the possible cause of it and which would be the proper further steps.

I hope to hear from you soon, I remain at your disposal for further medical assistance.

Brief Answer:
Lichen sclerosus is very likely the cause- helpful treatment explained below

Detailed Answer:
Hello and welcome back,

Thank you for your reply and the extra information and the photo provided. I carefully checked it.

The lesion seems like lichen sclerosis. This is a chronic skin condition that is thought to be due to the immune system affecting the skin and the dry skin may make it even worse.

As for treating it:
-You may use betamethasone ointment twice a day in the area for 2-3 weeks. Sometimes, longer treatment may be needed for it to completely go away but you should start to see an improvement within the first 7-10 days.

- The lesion tends to recur so you may need to repeat the treatment if it comes back or you may choose to apply the ointment 2-3 times a week for the next few months to prevent a recurrence.

- Also, it is helpful if you use vaseline ointment during the midday and when you are not using the betamethasone ointment so you can keep it moisturized.

- Try to not scratch the lesion. The betamethasone ointment will help settle the itchiness but also you can use cold compresses or oatmeal solutions to ease the itchiness.

- Avoid strong soaps and prolonged baths that may dry the skin.

- If you notice no improvement within 2 weeks with this treatment, you will need to see your doctor. The doctor may in some cases need to do a biopsy of the lesions for a more exact diagnosis.

I hope this answers your query. I remain at your disposal for further medical assistance.
