Acanthosis nigricans (pronounced: ah-kan-THO-sis NY-gruh-kans) is a skin condition. It causes thicker and darker patches or streaks, usually in skin creases and folds, such as the sides and back of the neck, armpits, elbow pits, and groin.
Overview. Acanthosis nigricans is a condition that causes areas of dark, thick velvety skin in body folds and creases. It typically affects the armpits, groin and neck. Acanthosis nigricans (ak-an-THOE-sis NIE-grih-kuns) tends to affect people with obesity.
Acanthosis nigricans (AN)
This skin condition causes dark patches of velvety skin in body creases such as your neck, armpits, or groin. Sometimes patches appear on your hands, elbows, or knees. Diabetes can cause skin infections or changes such as dark patches on the skin.
There are many reasons why a rash develops on the neck. Some of the most common causes are allergies, infections, and skin conditions. Understanding the possible causes is the first step in finding an effective treatment to help clear the rash and relieve discomfort.
Neck rashes can be caused by various things ranging from infections to underlying health conditions. Skin disorders are often the most common cause of a neck rash. They often appear red and itchy and can develop into bumps or spots. When you have a rash, it's important to monitor symptoms and how long it lasts.
Diabetes can cause changes in the small blood vessels. These changes can cause skin problems called diabetic dermopathy. Dermopathy often looks like light brown, scaly patches. These patches may be oval or circular.
An anxiety rash may appear as an itchy rash or hives, which may occur anywhere on the body. It occurs due to high levels of anxiety rather than other causes, such as allergies. Anxiety can increase the release of certain chemicals in the body, which can produce physical reactions, such as a rash.
When your doctor or nurse did your exam, they pointed out a dark skin patch on your neck, armpit, under the breast or a skin crease. This dark patch is called acanthosis nigricans (AAY-can-THO-sis NIG-ruh-cans), or AN. It is usually a sign that your body is making extra insulin that it cannot use well.
Liver spots are darkened patches of skin. They often develop on areas that have been exposed to ultraviolet (UV) light. Contrary to the name, liver spots don't have to do with your liver's function. While liver spots don't usually need treatment, you may want to treat them for cosmetic reasons.
Neck lines can appear commonly as part of the natural ageing process and are usually defined by wrinkles and sagging skin due to a loss of elasticity. As you age, your natural skin cell turnover decreases and the collagen that you naturally produce depletes.
A hickey, also known as a love bite, is a dark red or purple mark on your skin caused by intense suction. The neck is a common site for hickeys because of its easy access, but you can get them anywhere. When your partner sucks on and bites your skin, the pressure breaks little blood vessels under the surface.
Visible Skin Damage: The effects of sugar on the skin manifest as wrinkles, sagging, and a loss of facial volume, particularly noticeable in areas like the jowls and cheeks.
Rash symptoms
According to the American Academy of Dermatology (AAD), people with chronic kidney disease may have: small, dome-shaped, very itchy bumps. small bumps that have joined to form raised, rough patches. blisters on the hands, face, and feet that may crust over.
Leukemia rashes appear as tiny red spots or purple areas that do not fade when pressed; these are caused by low platelet levels and the rupture of very small blood vessels in the skin. These spots are also known as petechiae or purpura, depending on their size.
Lupus is a chronic condition that can affect most of a person's body, including their skin. People may experience a lupus rash on their neck or other body parts following sunlight exposure. Lupus is an autoimmune disease that results in systemic inflammation.
People may have a reddish purple rash of tiny dots or larger splotches, caused by bleeding from small blood vessels in the skin. If the liver function has been impaired for a long time, people may itch all over.
The most common signs of an aging neck are the development of vertical muscle bands, sagging skin, and excess fat deposits. Muscle bands occur due to the regular use of the platysma muscle, with the vertical lines representing the muscle edges.
Age spots are caused by overactive pigment cells. Ultraviolet (UV) light speeds up the production of melanin, a natural pigment that gives skin its color. On skin that has had years of sun exposure, age spots appear when melanin becomes clumped or is produced in high concentrations.
