We’re not sure what exactly causes nummular eczema, but certain things can trigger it. These include:
- Very dry or sensitive skin
- Being hurt by insect bites, scrapes, or chemical burns

|---|---|---|
| Coin-shaped lesions | Very dry skin | History of eczema |
| Itching and burning | Skin trauma | Trauma to the skin |
| Crusted lesions | Poor blood flow | Sensitive skin |
Seborrheic Dermatitis
Seborrheic dermatitis is also known as scalp eczema. It mainly affects oily areas of the body such as the scalp, face, and upper back. The condition can lead to discomfort and can impact daily activities.
Characteristics and Symptoms
The main signs of seborrheic dermatitis are scaly skin patches, redness, and dandruff. People may notice these flakes can be greasy or dry and may cause itching. About 3–10% of adults will face this issue sometime in their lives. It often affects adult males and teenagers the most.
Infants can get seborrheic dermatitis too, often showing up as cradle cap. This looks like yellow or flesh-colored flaky patches on the head. For adults, it might link to a history of psoriasis. This is different from the pattern of atopic dermatitis common in children.
Stress, hormonal changes, and illnesses can make seborrheic dermatitis worse. It might also appear with atopic dermatitis, affecting different body parts. It’s most common in adults aged 30 to 60. African Americans and those with darker skin may see a severe form known as petaloid seborrheic dermatitis.
Treatment for seborrheic dermatitis has improved. Recent breakthroughs include the FDA’s approval of Zoryve (foam 0.3%) for those 9 years and older. These treatments control flare-ups and ease symptoms, improving life quality for sufferers.
| Group Affected | Estimated Percentage |
|---|---|
| Adults | 3–10% |
| Infants (cradle cap) | N/A |
| Males (teens and adults) | Most common |
| Affected age range for peak prevalence | 30-60 years |
| Individuals with skin of color | Higher severity risk |
Neurodermatitis
Neurodermatitis is also known as lichen simplex chronicus. It leads to itchy, thick patches of skin that are very troubling. The symptoms of neurodermatitis appear as leathery lesions. They are often on the neck, scalp, ankles, and wrists. Adults aged 30 to 50, especially women and those with a history of certain skin conditions, are mainly affected. Stress, tight clothing, and dry skin are common triggers.
Symptoms and Affected Areas
The main symptoms of neurodermatitis are severe itching and a cycle of itch and scratch. This can cause more skin damage. The skin may become thick and change color in these spots. Although it’s rare in kids, those with atopic dermatitis can get it. There’s a higher risk for individuals with anxiety or psoriasis, which underscores the need for effective eczema management.
Management Strategies
To manage neurodermatitis, it’s crucial to stop the itch-scratch cycle. Doctors might suggest creams, like topical corticosteroids or salicylic acid. Wrapping the affected area and using cool compresses are also helpful. Oral meds, including antihistamines and some anxiety medications, can reduce scratching. Cognitive therapy and relaxation methods, such as yoga, greatly benefit overall health.
