Actinic Keratosis, also known as solar keratosis, is a scaly or crusty lesion on the skin that develops slowly and indicates the presence of sun damage. It is most commonly found on parts of the body frequently exposed to the sun including the bald scalp, face, ears, lips, backs of the hands or forearms, neck, and shoulders.

Actinic keratosis improves just two days after a freezing removal treatment.

Actinic keratoses are considered precancerous and can develop into a type of skin cancer called squamous cell carcinoma. In fact, some 40 to 60 percent of squamous cell skin cancers begin as untreated actinic keratoses.

Because of this, your doctor should be diligent in diagnosing, treating and monitoring actinic keratosis.

Annual Skin Examinations are yearly scheduled skin exams with a dermatologist. Did you know that skin cancer is the most common form of cancer in the U.S.? In fact, it is estimated that one in five Americans will develop skin cancer in their lifetime. Sun damage to the skin is cumulative over a person’s lifetime, so the average risk of skin cancer also increases as our life expectancy gets longer.

Just as you schedule your annual physical or trip to the dentist, it is important to conduct a self-examination of your skin each month and schedule a professional annual skin examination once a year. Skin cancer is a treatable condition, but early detection is key.

Basal Cell Carcinoma, also known as basalioma or basal cell cancer, is the most common type of skin cancer and carries the least amount of risk, though it still requires attention. If caught and treated early, basal cell carcinomas are not likely to be life-threatening, but they do have the potential to cause disfigurement of the skin tissue.

Almost one million new cases of basal cell carcinoma are diagnosed each year in the U.S., and up to 30% of Caucasians may develop basal cell carcinomas in their lifetime.

Basal cell carcinoma can be treated by removing the affected area.

Skin cancer is considered low risk when the affected cells remain clustered in a single group. Both basal cell carcinoma and squamous cell carcinoma are rarely life-threatening. Though it is unlikely to spread to other parts of your body, if left untreated, basal cell carcinoma can move into nearby bone or other tissue.

Basal cell carcinoma typically begins as a small, shiny bump on the face, although it can occur on any part of the body.

Cryotherapy, or “cryosurgery,” is a simple, non-invasive procedure in which liquid nitrogen is used to freeze and destroy growths on the surface of the skin. This is an effective treatment for precancerous skin lesions (actinic keratoses), as well as other skin conditions such as warts, skin tags and moles.

Applying liquid nitrogen to skin lesions allows dermatologists to target the damaged skin cells and destroy them at the cellular level. After freezing, the affected area may blister and scab over, and should heal within three to six weeks.

Our dermatology team uses cryosurgery to treat a wide range of conditions. It offers a number of advantages: Cryotherapy is a simple, affordable outpatient procedure, the discomfort level is minimal, and there is a low risk of infection.

In cryotherapy treatment, liquid nitrogen is applied to the skin to freeze and destroy the affected tissue.

Melanoma, the deadliest of skin cancers, only accounts for about 4 percent of all skin cancer cases, but causes about 79 percent of skin cancer deaths.

Melanoma is a cancer of the skin that begins in the melanocytes, which are the cells that produce the pigment melanin. It is the leading cause of cancer death in women 25 to 30 years old and the second leading cause of cancer death in women 30 to 35 years old.

In some cases, melanoma occurs in melanocytes throughout the body, even if those parts have never been exposed to the sun.

Skin cancer is the most common form of cancer in the U.S. with more than 3.5 million cases diagnosed each year.

Skin cancer is the result of uncontrolled growth of abnormal skin cells that takes place when skin cells suffer DNA damage and then mutate, causing them to multiply rapidly and form malignant (cancerous) tumors. Most skin cancers develop on the visible outer layer of the skin (the epidermis), particularly on sun-exposed areas such as the face, head, hands, arms and legs. They are usually easy to detect with a skin examination, which increases the chances of early diagnosis.

There are different types of skin cancer, each named for the type of skin cell from which they originate. The most common type of skin cancer is basal cell carcinoma. Almost one million new cases of basal cell carcinoma are diagnosed each year in the U.S. Most skin cancers fall into one of three categories:

• Basal Cell Carcinoma
• Squamous Cell Carcinoma
• Melanoma

There are often warning signs that cancer is developing. The most common are pre-cancerous lesions called actinic keratoses that often develop on sun-exposed areas. These tumors replace normal surrounding tissue and generally do not spread to other areas.

Skin cancer is considered low risk when the affected cells remain clustered in a single group. Both basal cell carcinoma and squamous cell carcinoma are rarely life-threatening.

Skin cancer is considered a high risk when cells have invaded surrounding tissues. The third most common skin cancer, malignant melanoma, can be life-threatening if not diagnosed and treated early.

If skin cancer is detected before it has spread to surrounding tissues, the chances of a complete recovery and cure are excellent. High-risk forms of cancer like melanoma require more aggressive treatments.

Suspicious moles should be watched closely, as they might indicate a cancerous growth.

Squamous Cell Carcinoma is a common form of skin cancer that develops in the squamous cells that make up the outer layer of the skin. Although it is usually not life-threatening, it can be aggressive in some cases.

If left untreated, squamous cell carcinoma can grow large or spread to other parts of your body, causing serious complications.

Your dermatologist will be able to examine your skin for signs of squamous cell carcinoma.

Acanthosis Nigricans is a condition that causes the skin to become discolored in the creases and folds of your body. This dark colored skin sometimes becomes thickened and often shows up in the armpits, groin and the folds of the neck.

Acne is a dermatological condition caused by inflammation and mild infection in clogged pores. If not properly treated, acne can cause emotional distress, low self-esteem, and depression. In severe cases, it can even lead to permanent scarring.

While not a serious physical health threat, acne is an embarrassing skin problem that can be life-altering for many patients. Though it is most common among teenagers, acne can affect anyone, regardless of age or gender, and can be mild, moderate or severe.

Alopecia Areata, also known as spot baldness, is a type of hair loss in which your immune system attacks hair follicles. This leads to areas of baldness on the scalp and body. In severe cases, a person with alopecia may even lose the hair of their eyebrows and eyelashes.

Athlete’s Foot earned its name because this contagious fungal infection is commonly seen in athletes, who may wear sweaty socks for long periods of activity. It affects the skin on the feet and, left untreated, can spread to toenails and even to your hands.

Skin affected by athlete’s foot appears crusty or scaly and is likely to itch.

Cold sores, which are also called fever blisters, are groups of blisters that appear on the lip and around the mouth. The blisters may break open and leak a clear fluid and then scab over. They may take up to two weeks to heal. They are caused by the herpes (HSV) virus.

Cold sores can be uncomfortable and embarrassing.

Cysts are pockets of tissue (sacs) that may become filled with pus, fluids, skin cells, and even air.

They are fairly common on the skin and can appear anywhere on the body. Cysts may feel like a pea under the surface of the skin, but without removal, they can grow significantly larger over time. In most cases, cysts are not painful, and they grow slowly. There are different types of cysts as we’ll discuss in the next section, and the vast majority of these skin growths are benign (not cancerous). Not all cysts will require treatment, but it is vitally important to have any lump under the skin evaluated and diagnosed by a board-certified dermatologist because some soft tissue malignancies (growths that are cancerous) can present like a cyst. Before recommending removal or other cyst treatments, your dermatologist will examine the growth to determine whether it is likely to cause you pain, become infected, or otherwise lead to skin health issues.

Skin cysts, which can appear anywhere on the body, are usually painless and grow slowly.

Dandruff is a condition of the scalp which causes flaking and itching of the skin. It is more common in people with the skin conditions seborrheic dermatitis, psoriasis and eczema, and also can be a reaction to hair or skin products.

Dandruff flakes can be visible on the shoulders.

Dermatitis, also sometimes referred to as eczema, is a common condition characterized by an itchy rash and inflamed skin. There are many different types of dermatitis and symptoms can range in severity from mild itching and redness to severe blistering and cracked skin.

Dermatitis is a group of diseases and comes in many forms, but all are characterized by inflammation of the skin, redness and itchiness.

Atypical moles, also known as dysplastic nevi, are unusual-looking benign (noncancerous) moles.

A dysplastic mole is one that, when viewed on a cellular level, has features unlike those of a healthy, benign mole. A benign mole will have a regular pattern of coloration and pigment, even borders, symmetry, and a tan or pink color. Dysplastic moles can be asymmetric, have indistinct borders, or contain multiple colors or very dark pigment.

Dysplastic moles are often spotted as the “ugly duckling” on a patient’s skin. Any departure from the typical mole a person’s skin makes may be dysplastic. They can appear anywhere on the body, but in most cases are found on the back, chest, buttocks, breasts, or scalp.

People with atypical moles are at a higher risk of developing melanoma.

Eczema, also sometimes referred to as dermatitis, is a common condition characterized by a certain type of inflammation in the skin. There are many different types of eczema and symptoms can range from mild itching and redness to severe blistering and cracked skin. Whether you’re newly diagnosed with eczema or you’ve struggled with this chronic skin condition for years, you know that finding a treatment that works for you isn’t just important – it’s essential. Without proper and effective interventions, people with eczema can experience significant discomfort, itching, and inflammation.

You might ask, what does hair loss have to do with skin?

Hair is actually a protein filament that grows from follicles deep in the skin up through the top layer of your skin. Your hair helps to regulate body temperature and also serves to protect your scalp. Almost everyone experiences some degree of hair loss at some point in life.

Head lice is a common condition, especially among children. While it may sound creepy or embarrassing to have small mites (or nits) in your hair, it’s actually a very manageable condition that is typically easy to treat right at home. On this page, you can learn more about how to get rid of lice from your head and your home.

Herpes simplex virus, often referred to simply as HSV, is an extremely common viral infection impacting millions of people in the U.S. alone.

Hidradenitis suppurativa is rare skin condition in which small, painful lumps develop under the skin, usually in areas where the skin rubs together (armpits, groin, between the buttocks, under the breasts, etc.) or in areas near hair follicles where many oil and sweat glands are present. Sometimes, the lumps may break open and smell, or they may create tunnels under the skin.

It can continue for many years, may worsen over time and can have serious effects on your daily life and emotional well-being, particularly during outbreaks.

If left untreated, Hidradenitis suppurativa can cause longstanding problems in your day-to-day life.

Lipomas: Understanding & Addressing Benign Fatty Growths

A lipoma is a benign fatty growth, most often located in the deep aspect of the skin (subcutaneous tissue).  These growths arise from the normal fat cells in our subcutaneous tissue and are benign (non-cancerous).  However, there is a very rare form of cancer called liposarcoma, which is a malignant growth from these fat cells.  Lipomas are relatively common, impacting about 1% of people.  However, researchers suspect that lipoma incidence is significantly underreported.

Melasma is a fairly common skin condition that creates the appearance of brown to gray-brown patches of skin, usually on the face. It can also occur on the neck and forearms and is the result of the body producing too much melanin, that natural substance that colors our hair, skin, and eyes.

If you’re dealing with dark spots or patches on your skin from the chronic condition melasma, the U.S. Dermatology Partners team can help you to improve the appearance of these spots and minimize the risk for future flare-ups of the condition.

Molluscum contagiosum is a contagious skin disease that appears as pink or flesh-colored bumps on the skin. It is caused by skin-to-skin contact as well as from sharing towels, clothing or touching infected surfaces. It can also be acquired through sexual contact.

For adults, bumps are most often found on the face, neck, armpits, arms and hands. They may also appear on the genitals, abdomen and inner thighs.

Once you are infected with the virus, it can spread to other parts the body, especially if you pick or scratch at the bumps or touch other parts of your skin after touching the bumps. (This is called self-re-infection.)

Molluscum contagiosum is a contagious skin disease that appears as pink or flesh-colored bumps on the skin.

A fungal infection of the toenails or fingernails typically looks like white or yellowed nails that may also be thick and brittle. The infection could affect one nail or part of a nail, or it could affect multiple nails. If left untreated, fungal infections can lead to permanent nail damage.

Fungal infections of the nails lead to white or yellowing nails that can be thick or brittle.

Telemedicine, also known as online dermatology, telehealth, or teledermatology, is the use of telecommunications technology to provide care across a distance. This includes using the Internet, cell phones, SMS messaging and even satellites to allow physicians and patients to communicate medical information. This technology has been available for over a decade now, but as it has gotten better and better, telemedicine has now become much more available, easy to use, and secure. If used in the right way, it is one of the best ways that we can improve access to care.

Because dermatology is a very visual field and a specialty in high demand, patient access is often challenged by long wait times. Meeting a dermatologist online can be a great way to provide patients with increased access to skin care. Teledermatology involves the use of real-time video streaming, or more commonly the transmission of still images, pictures, and video in combination with a patient’s medical information collected via questionnaire. Teledermatology can be utilized in many ways including physician-to-physician consultations, triage, follow-up care, and patient education.

When your child develops a persistent rash or other skin condition, your goal is to find the appropriate treatment as quickly as possible to keep them comfortable and healthy.

Psoriasis is a chronic autoimmune inflammatory condition that causes patches of skin to become red, inflamed, and bumpy. This disease affects more than 8 million people in the U.S.

Psoriasis occurs when the immune system mistakes skin cells for a virus or other infection and responds by producing more skin cell growth. This can be triggered by stress, anxiety, injuries to the skin, infections and hormonal changes.

Despite the name, ringworm is not caused by worms; it is a skin infection caused by a fungus. It can be caused by touching another person who has the infection, or by sharing items that the person has been in contact — such as towels, bedding, chairs and clothes. It can also be caught from animals with fungal infections and, rarely, from contact with fungi in the soil.

Ringworm has a reddish, circular appearance.

Rosacea is a fairly common skin condition that causes redness in your face. In some cases, it may also produce small, red, pus-filled bumps. Typically these signs and symptoms may flare up for a period of weeks to months and then diminish for a while.

Rosacea may sometimes be mistaken for acne, an allergic reaction or other skin problems. It is believed to be caused by a combination of hereditary and environmental factors.

Seborrheic keratosis is one of the most common noncancerous skin growths found in older adults. It most commonly appears as a brown, black or light tan growth on the face, chest, shoulders or back. Although they are not cancerous, they can look like skin cancer.

Seborrheic keratosis is also known as seborrheic verruca or a senile wart.

Shingles, also known as herpes zoster, is a painful skin rash that occurs when the virus that causes chickenpox reactivates.

Typically, shingles appears on a small area on one side of the face or body. The rash is often painful because it travels up nerve roots (which supply sensation to your skin) to the area of skin supplied by those specific nerve roots.

Shingles is a painful skin rash that occurs when the virus that causes chickenpox reactivates.

Skin tags are small, soft skin growths that can occur anywhere on the body but are most common on the eyelids, neck, armpits, groin folds and under the breasts. They are harmless but they can be annoying, particularly if they are in an area where they are rubbed on by clothing. They may be flesh-colored, pink or may darken.

Skin tags are small, soft growths that can be skin-colored, pink, or may darken.

The sun can age and burn your skin, and it can also cause damage on the cellular level, leading to skin cancer. The good news is, the U.S. Dermatology Partners team can help you formulate a plan to prevent sun damage and repair the effects of the sun’s UV rays so that you can go out and enjoy a sunny day. Learn more on this page or contact U.S. Dermatology Partners to schedule an appointment with us.

Individuals who are prone to sunburn are thought to be genetically predisposed to skin cancer. Risk is also increased when exposure to UV rays is excessive. Sunscreen helps prevent the damaging effects of ultraviolet radiation, including skin aging and skin cancer like melanoma and squamous cell carcinoma.

Sunscreens are rated and labeled with a sun protection factor (SPF) that measures the fraction of sunburn-producing UV rays that reach the skin. The higher the SPF, the greater the protection.

Sunscreen is a topical product that is used to reflect or absorb some of the ultraviolet rays from the sun.

Vitiligo is an autoimmune disease in which white patches of skin appear on different areas of the body. This happens when melanocytes, the cells that make pigment in the skin, are destroyed. In addition to the skin, it can affect the mucous membranes of the mouth and nose as well as the eyes. Its cause is not known.

Vitiligo causes white patches on different areas of the body.

Warts are benign, non-cancerous growths that appear on the skin as the result of a virus called human papillomavirus, or HPV. They are contagious and are spread by contact – either with the wart or something that touched the wart. Cut or damaged skin is more vulnerable to warts.

Botox, the commercial brand name for botulinum toxin (BTX), is an injectable cosmetic dermatology treatment that reduces the appearance of fine lines and wrinkles on the face.

Unlike injectable wrinkle fillers, which work by filling a crease in your skin with another substance, Botox actually relaxes targeted muscles to reduce the look of lines in the face. This results in smoother skin with a more youthful appearance.

Each Botox injection relaxes key facial areas by temporarily paralyzing specific muscles. This temporarily removes wrinkles and improves the look of laugh and frown lines, skin bands on the neck, crow’s feet, forehead creases and more.

Botox is a quick procedure that is done in just minutes in your doctor’s office.

Although it was originally developed to treat eye muscle disorders, Botox has become popular cosmetically and this is now its primary use. In fact, Botox injections are now the most common cosmetic treatment in the U.S., with 6.3 million procedures done in 2013. Because Botox inhibits the release of certain neurotransmitters, it is also sometimes used to treat chronic migraines.

Keloids are raised, red scars created by excessive healing of skin wounds, such as burns, cuts and acne. They are the result of an overproduction of collagen as the skin tries to repair itself. Keloids also can occur after piercings, tattoos or surgery and often times are itchy and painful. They can grow for years and sometimes show up three months or longer after the injury occurred.

Keloid are caused by an overproduction of collagen as the skin tries to repair itself.

Keratosis pilaris is a common skin condition characterized by small, hard bumps that may make your skin feel like sandpaper. Most often they appear on your upper arms, thighs and buttocks, and sometimes are accompanied by redness or swelling. In some cases they may appear on your face.

It is caused by a buildup of keratin, a protein that protects skin from infections. When a buildup forms, it blocks the opening of a hair follicle and creates the bumps, but doctors don’t know what triggers the buildup.

Keratosis pilaris, a condition where keratin overproduction causes clogged pores, can lead to red bumps and irritation on the skin.
