What is the treatment for a recurring rash behind the ear?

Hello,

Welcome to icliniq.com.

I saw the picture (attachment removed to protect patient identity).

You have erythematous (red) papules (bumps) behind the ear. I can list a few possibilities:

1. Papular eczema.
2. Allergic contact dermatitis.
3. Insect bite reaction.

I would like to know:

1. Is this rash itching or painful?
2. Are you on any medication for this?
3. Do you have similar rashes anywhere else on the body?
4. Since how many days do you have this?

Thank you for consulting me.

Hi,

Welcome back to icliniq.com.

I read and understand your concern.

Few bumps have central punctum. Features are more consistent with insect bite reaction. When an insect bites, there can be an irritant or allergic reaction to that bite forming some bumps in the area around the bite or even involving other body sites. If the lesion is recurrently appearing at the same site every time, then papular eczema should be ruled out. Any history of eczema? A family history of eczema? Did you have fever before these rashes appeared? Do you have similar bumps on the back and chest or scalp? Another possibility is folliculitis, but there will be pustules around the opening of hair follicles, usually seen on the back, chest, and arms.

Insect bite reaction responds well to:

1. Calamine (zinc oxide and 0.5 % iron oxide) lotion, it helps with redness.
2. Topical Hydrocortisone 2.5 % cream, apply to the bumps at night for not more than two weeks. Consult your specialist doctor, discuss with him or her and start taking the medicines with their consent.

Looking forward to your response in order to help you.

Thank you.
