Acne is the most common skin condition that people experience. Most people develop acne to some degree during their lifetime. Though it primarily affects teenagers undergoing hormonal changes, many people will develop acne as adults. Acne might be mild (few, occasional pimples), moderate (inflammatory papules), or severe (nodules and cysts). Scarring can occur. Treatment depends on the severity of the condition.
Rosacea is a common disorder that most usually affects facial skin. It causes redness on the nose, chin, cheeks, and forehead. Over time, the redness may become more intense, taking on a ruddy appearance. Small blood vessels may become visible. If rosacea is not treated, red solid bumps and pus-filled pimples can develop. The disorder can cause the nose to take on a bulbous, swollen appearance called rhinophyma. Rosacea can affect the eyes, causing them to feel irritated and to appear bloodshot or watery. Styes may occur. This is called ocular rosacea.
Lichen planus is a chronic, itchy rash that can appear in just one area of the body or affect several parts of the body at the same time. Most commonly, it is seen on the skin of the arms and legs and inside the mouth. Lichen planus can also affect the nails and the skin in the genital area.
Atopic dermatitis is a skin condition that may be passed on from parents to children. It can occur at any time in life, but usually first appears when children are infants, and may not diminish until early adulthood. More than half of infants with atopic dermatitis grow out of the condition by school age, though flare-ups can occur throughout life.
The condition is most common among families who have a history of environmental allergies. Though food allergies may cause flare-ups, removing suspected foods (such as eggs, milk, fish, wheat, and peanuts) from your child's diet is not likely to cure the problem. If you suspect that a food is worsening the rash, discuss this with your healthcare provider.
Atopic dermatitis can also worsen when the skin comes into contact with irritating substances such as harsh soaps and scratchy, tight-fitting clothing. Scratching can also promote infections that require treatment.
Eczema is a general term for a group of conditions that cause the skin to become inflamed, red, dry, bumpy, and itchy. However, this term is most often used to refer to a condition called atopic dermatitis. In atopic dermatitis, skin barrier function (the "glue" of the skin) is damaged. This loss of barrier function makes the skin more sensitive and more prone to infection and to becoming dry.
Vitiligo (vit-il-EYE-go) is a skin disorder that causes the skin to lose its color. Smooth lighter or white areas (called macules or patches) appear on a person’s skin. If vitiligo occurs in a hair-bearing area, the hair in those areas also may turn white.
The condition occurs when melanocytes (the skin cells that produce melanin, the chemical that gives skin its color, or pigmentation) are destroyed by the body’s immune system.
fungal, bacterial and viral skin infections
The skin provides a remarkably good barrier against bacterial infections. Although many bacteria come in contact with or reside on the skin, they are normally unable to establish an infection. When bacterial skin infections do occur, they can range in size from a tiny spot to the entire body surface. They can range in seriousness as well, from harmless to life threatening.
There are two main categories of hemangiomae — red and pigmented hemangiomae. Red hemangioma are a vascular (blood vessel) type of birthmark. Pigmented hemangioma are areas in which the color of the birthmark is different from the color of the rest of the skin.
Throughout our lives, we have experiences that injure our skin, leaving behind a scar. The formation of scars depends on many factors, including:
How large the wound is;
The person’s age, sex, and ethnicity (nationality/heritage); and
Genetic (inherited) factors.
autoimmune skin diseases
Autoimmune blistering disorders are a group of rare skin diseases. They happen when your immune system attacks your skin and mucous membranes -- the lining inside your mouth, nose, and other parts of your body. This causes blisters to form.
Researchers have found many types of this disorder. Although there's no cure for them, your doctor can give you treatments to help heal the blisters and prevent complications.
urticaria and angioedema
Most people recognize hives - those sudden instances of swelling of the skin that usually itch, burn, or sting. Less familiar, however, is the condition's close cousin, angioedema, a similar kind of swelling of the deeper tissues beneath the skin.
Hives and angioedema are related because they are similar reactions to the same basic cause, a release in the skin of chemicals including histamine. In most cases, histamine and these other chemicals are a byproduct of the body’s specialized mast cells as they go about their job of destroying allergens, which are any substances that cause allergic reactions. Fighting allergens is not the only way that histamine is produced, however. Irritation caused by sunlight, some medications, and unknown sources can make mast cells release histamine, too.
Whatever the reason for its release, histamine produces hives and angioedema by dilating the small blood vessels in the skin and causing fluid to leak from them. This in turn generates swelling.
Hives (urticaria) can appear anywhere on the body in splotches as small as a pencil eraser and as large as a dinner plate. These splotches sometimes join together to form larger areas. Whether large or small, hives often fade within a few hours, but are replaced by new ones in the same or different areas.
Angioedema usually causes deep swelling around the eyes and lips, and sometimes swelling of the genitals, hands, and feet. In rare instances, angioedema of the throat, tongue, or lungs can block the airways, making breathing difficult and potentially endangering the life of the victim.
