Dermatophytid is a skin condition that is a reaction to a fungal infection in another part of the body. The condition is not caused by the fungus itself, but by the body's immune response to the fungus.

Causes

Dermatophytid is caused by a reaction to a fungal infection elsewhere in the body. The most common types of fungi that cause these reactions are dermatophytes, which are a group of fungi that can cause skin, hair, and nail infections. The body's immune response to the fungal infection can cause skin lesions to appear in areas of the body that are not infected with the fungus.

Symptoms

The main symptom of dermatophytid is a rash that appears on the skin. This rash is often itchy and may be accompanied by other symptoms such as redness, swelling, and blistering. The rash can appear anywhere on the body, but it is most commonly found on the hands, feet, and arms.

Diagnosis

Diagnosis of dermatophytid is usually made by a dermatologist, who will examine the skin and may take a skin scraping or biopsy to confirm the diagnosis. The dermatologist may also ask about any recent fungal infections, as this can help to confirm the diagnosis.

Treatment

Treatment for dermatophytid involves treating the underlying fungal infection. This can be done with antifungal medications, which can be applied topically or taken orally. In some cases, the skin lesions caused by dermatophytid may also need to be treated with topical steroids to reduce inflammation and itching.
