Causes of Thick Scaly Skin on the Neck

Causes of Thick Scaly Skin on the Neck

There are a few causes of thick, scaly skin on your neck. In most cases, the condition is chronic and will crop up again and again throughout your lifetime. Proper diagnosis is important so you can implement the proper treatment and clear your skin as quickly as possible.

Eczema

Eczema isn't a specific condition, but rather a collection of conditions that cause a thick, scaly rash to break out on the neck and other parts of the body. The most common form of eczema is atopic dermatitis. It usually begins in childhood and is often triggered by common allergens, such as detergents, animal dander or fruit juices. If you have eczema, you may find that clothing that rubs at the neck or excessive sweating can trigger an outbreak. Avoid scratching the rash, because doing so can cause an infection. Princeton University reports that eczema is not contagious, although it does tend to run in families.

Impetigo

If you've developed a crusty, yellow rash on your neck where there were formally blisters, you may have developed impetigo. Impetigo is a skin infection that is more common in children than adults. It is a bacterial infection caused by either group A streptococcus or staphylococcus aureus, according to KidsHealth from Nemours. The infection can be spread from person-to-person through direct contact or through contact with towels and clothing that touched the rash on an infected person. You should wash the area with soap and water and spread antibacterial ointment over it until the infection heals. If a fever accompanies the thick, scaly skin on your neck or if the impetigo seems to be worsening or spreading, contact your physician right away.

Psoriasis

Psoriasis is an auto-immune condition that affects the skin, and it can be triggered by stress, medications or changes in the weather. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, psoriasis occurs when a type of white blood cell mistakenly activates and triggers an immune response that causes your skin cells to rapidly duplicate and shed. A rash caused by psoriasis is usually red and appears to be covered with silvery scales. The "scales" are the excessive skin cells that are flaking off. Psoriasis can be difficult to diagnose because it mimics the symptoms of other skin conditions. Your doctor will likely start you off with a topical medication to treat psoriasis and may add additional therapies if your psoriasis does not respond to initial treatment.
