Phrase skin lesions cover a wide range of color changes, lumps and bumps, patches, rashes and other things on or under skin. Freckles, moles, areas of itchy, dry skin and many other marks all qualify as skin lesions. Many are normal, but few can be deadly. University of Minnesota Health Dermatologist Lori Fiessinger, MD, shares five things you should know about skin lesions. But not all dark spots on your skin are Moles, Fiessinger note. They can also be harmless freckles or sun spotswhich are flat spots that occur in sun - expose areas due to UV exposure. Brown spots that occur after age 40 are often seborrheic keratosis, also know as wisdom or age spots. They are elevated brown bumps that can have a waxy or crusty texture. Though their appearance may be concerning, they are not made up of melanocytes, so they do not carry risk of skin cancer. Scar tissue can also appear as brown spots or bumps on skin. Dermatofibroma is a flat or slightly elevated bump with white to purple scar tissue center surrounded by brown rim. Dermatofibromas are benign. Asymmetry - Divide mole in half. If one side looks different than the other, that could be cause for concern. Borders - Moles should have defined cutoff at edges. Moles that appear to trail off into skin without distinct edge should be examined by dermatologist. Color - If a single mole contains more than two colorsincluding, different shades of brown, black, blue, or pinkit, may need to be evaluate. Diameter - If a mole is bigger than the width of a pencil eraser, it needs to be check. Evolving - Changes to the shape or appearance of existing mole are a red flag. So is the development of new mole after age 40. If you think personal care product may be causing rash, Fiessinger recommends switching from your current product to a gentler, fragrance - free version. People can develop sensitivities to products at any time, even if you have been using the same product for years without experiencing any negative effects. In addition, companies are always changing the ingredients and formulations of their products, so there may be new substance in your go - to product that you are reacting to. If you switch products and the rash doesnt go away, then it is time to visit a dermatologist to determine the cause.
This is the most severe and long - lasting form of eczema. It's characterized by inflamed skin that may crack and release clear fluid when scratch. People with atopic dermatitis often experience flares, during which symptoms worsen, and remissions, when symptoms improve or clear up, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Sometimes mistaken for dry skin, this form of eczema produces dry, thick, scaly patches on hands that may crack and bleed. Like contact eczema, hand eczema is triggered by various irritants and allergens. As such, it is most often found in people who work in cleaning, catering, hairdressing, healthcare, and mechanical jobs. Those who had atopic dermatitis or eczema are more likely to develop hand eczema compared with those who have had atopic dermatitis, according to the American Academy of Dermatology. Also know as scalp eczema or dandruff, this is a chronic condition in which white or yellow scaly patches of skin develop in oily areas, such as the scalp, face, ears, and groin. Unlike other forms of eczema, Seborrheic dermatitis is not a type of allergic reaction, and microorganisms that live on the skin can contribute to the condition.

Exactly what causes acne? Acne develops when cells and natural oils begin to block up tiny hair follicles in the skin. Bacteria work their way into plug up follicles and start multiplying. When the body's immune cells move in to attack bacteria, results of battle are classic symptoms of acne - swelling, redness, and pimples. Acne medications help by interrupting this process in different ways. Some over - counter and prescription acne creams help by unplugging follicles. Others - such as antibiotics - kill bacteria that move into follicles. Oral retinoid Accutane works differently by reducing the amount of oil secreted by glands in the skin. There is no best acne treatment. Some people do fine using one acne cream, although many need a combination of approaches to control their teen acne.
Herpes simplex infection of mouth and face, known as orofacial herpes simplex, herpes labialis, cold sores, or fever blisters, is a common, recurrent skin condition associated with infection by herpes simplex virus. Orofacial HSV usually appears as small blisters or sores around the mouth, nose, genitals, and buttocks, though infections can develop almost anywhere on skin. Furthermore, these cold sores may periodically come back to the same sites. Infections with HSV are very contagious and are spread by direct contact with skin lesions. There are 2 types of HSV: herpes simplex virus type 1 and herpes simplex virus type 2. Hsv - 1 infections usually occur around the mouth, lips, nose, or face, while HSV - 2 infections usually involve genitals or buttocks. However, HSV - 1 can sometimes cause infections in the genitals or buttocks, while HSV - 2 can occasionally cause infections around the mouth, lips, nose, or face. Both types of virus produce 2 kinds of infections: primary and recurrent. Because it is so contagious, HSV causes primary infection in most people who are exposed to the virus. However, only about 20% of people who are infected with HSV actually develop visible blisters or sores. Appearing 2 - 12 days after person's first exposure to HSV, sores of primary infection last about 1 - 3 weeks. These sores heal completely, rarely leaving scar. Nevertheless, viruses remain in the body, hibernating in nerve cells. Certain triggers can cause hibernating viruses to wake up, become active, and travel back to the skin. These recurrent HSV infections may develop frequently, or they may never develop. Recurrent infections tend to be milder than primary infections and generally occur in the same location as primary infection. Most people get cold sores as children, through contact with friend or family member who is already infected with HSV. It can be spread by kissing, sharing eating utensils or drinking vessels, or by using the same towel.
A blister, which is also called vesicle by medical professionals, is a raised portion of skin that is filled with fluid. Youre probably familiar with blisters if youve ever worn ill - fitting shoes for too long. This common cause of blistering produces vesicles when friction between your skin and shoe results in layers of skin separating and filling with fluid. Blisters are often annoying, painful, or uncomfortable. But in most cases, they are symptoms of anything serious and will heal without any medical intervention. If you ever have unexplained blistering on your skin, you should see your healthcare provider for diagnosis.
Hives appear on skin as wheals that are red, very itchy, smoothly elevated areas of skin often with a blanch center. They appear in varying shapes and sizes, from a few millimeters to several centimeters in diameter anywhere on the body. It is estimated that 20% of all people will develop urticaria at some point in their lives. Hives are more common in women than in men. One hallmark of hives is their tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours. Individual hives usually last no longer than 24 hours. Outbreaks that look impressive, even alarming, first thing in the morning can be completely gone by noon, only to be back in full force later in the day. Very few skin diseases occur and then resolve so rapidly. Therefore, even if you have no evidence of hives to show doctor when you get to the office for examination, diagnosis can be established based upon accurate recounting of your symptoms and signs. Because hives fluctuate so much and so fast, it is helpful to bring along photographs of what the outbreak looks like at its most severe point. Swelling deeper in the skin that may accompany hives is called angioedema. This swelling of hands and feet, as well as face, can be as dramatic as it is brief. Hives appear when histamine and other compounds are released from cells called mast cells, which are normally found in skin. Histamine causes fluid to leak from local blood vessels, leading to swelling in the skin. Hives are very common and are not considered contagious. Although annoying, hives usually resolve on their own over a period of weeks and are rarely medically serious. Some hives may be caused by allergic reaction to such things as foods, infections by different organisms, medications, food coloring, preservatives and insect stings or bites, and chemicals; but in the majority of cases, no specific cause is ever find. Although people may find it frustrating not to know what has caused their hives, maneuvers like changing diet, soap, detergent, and makeup are rarely helpful in preventing hives unless there is excellent temporary relationship. Since hives are most often produced by immune mechanism,ss condition is not contagious. If infectious disease were cause of hives in a particular person, then it is possible, but not likely, that infected contact could develop hives. Having hives may cause stress, but stress by itself does not cause hives. Hives fall into two categories on the basis of time they have been present: acute urticaria and chronic idiopathic urticaria. Since hives are so common and acute urticaria, by definition, resolves spontaneously, physicians do not generally expend much time or expense on evaluating the cause of hives of less than eight weeks duration. Symptoms of ordinary hives flare up suddenly and usually for no specific reason. Welts appear, often in several places.
