What Is Actinic Keratosis?

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 two days after a freezing removal treatment

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.

What Is an Annual Skin Examination?

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.

 

What Is Basal Cell Carcinoma?

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 treatment

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.

What Is Cryotherapy?

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.

What Is Melanoma?

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.

 

What is Merkel Cell Carcinoma?

Skin cancer is a common concern in the U.S.  Estimates reported by the American Academy of Dermatology suggest one in five people in the U.S. will develop some form of skin cancer. Merkel cell carcinoma is among the rarest forms of skin cancer, wherein estimates by the Skin Cancer Foundation suggest that only one in 130,000 people in the U.S. will be diagnosed with Merkel cell carcinoma. Like melanoma, Merkel cell carcinoma is an aggressive form of skin cancer with a high mortality rate.  As with most potentially aggressive malignancies, early detection is the best way to decrease the risk of death associated with Merkel cell carcinoma. You can learn more about diagnosis and treatment options for Merkel cell carcinoma on this page.

Merkel cell carcinoma is a rare form of skin cancer that arises from Merkel cells, cells that reside deeper in the skin and function to send ‘touch’ signals from outside the skin to the inside of the body.  The diagnosis of Merkel cell carcinoma is ultimately made by an assessment under the microscope after a skin biopsy has been performed.  Skin biopsies are interpreted by dermatopathologists, doctors who specialize in evaluating skin under the microscope.  Dermatopathologists are well equipped to make this diagnosis accurately when skin tissue is submitted in a biopsy specimen.  Unfortunately, when Merkel cells become cancerous, they also become aggressive.  Merkel cell carcinoma can metastasize (spread) quickly, making it one of the most aggressive types of cancer.  While treatment for Merkel cell carcinoma may be successful, even with treatment Merkel cell carcinoma may evade what appears to be disease remission, and recur.

 

What Is Mohs Surgery?

Mohs surgery offers the highest cure rates for all non-melanoma skin cancers. For certain cases of the most common types of skin cancer — squamous cell carcinoma and basal cell carcinoma — the cure rate can be as high as 99 percent.

Mohs surgery is a highly specialized surgical technique used to treat non-melanoma skin cancers in which the surgeon removes all of the visible cancer, plus a small margin of the surrounding healthy tissue and examines it to ensure that all cancer cells have been removed at the time of surgery.

Before and After Mohs Surgery Technique

During Mohs micrographic surgery — named after Dr. Frederic Mohs, who first performed it in the 1930s — cancer is removed from the skin layer by layer until all cancerous cells have been removed. This type of surgery is most commonly used for cancers that have a high risk of re-occurrence. This technique allows for complete removal of the skin cancer while minimizing the removal of surrounding healthy skin.

What Is Sebaceous Carcinoma?

A rare and aggressive form of skin cancer, sebaceous carcinoma is sometimes referred to as sebaceous gland carcinoma, sebaceous gland adenocarcinoma or meibomian gland carcinoma.

Sebaceous carcinoma can develop in any sebaceous glands, which lubricate the skin, but it most often begins on or around the eyelids. If it is found and treated early, treatment is often successful. However, if sebaceous carcinoma spreads, it can be deadly.

Because sebaceous carcinoma can appear to be a benign growth such as a stye, diagnosis is often delayed, which increases the risk of death. If you notice a growth on your eyelid, it’s important to make an appointment with your dermatologist. The sooner sebaceous carcinoma is diagnosed and treated, the better the outcome.

What Is Skin Cancer?

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:

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.

What Is Squamous Cell Carcinoma?

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.

What Is Acanthosis Nigricans?

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.

Effective Acne Solutions

If you’ve struggled with moderate to severe acne, including cystic or nodular acne, you know that many common acne treatments aren’t effective for everyone. Fortunately, the physicians at U.S. Dermatology Partners commonly prescribe Accutane (isotretinoin) for the treatment of those patients with acne that is unresponsive to other therapeutic options.

What Is Acne?

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.

What Is Alopecia Areata?

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.

Benign Lesion Destruction means the ablation of benign, premalignant, or malignant tissues by any method and not usually requiring closure.

What Are Benign Lesions?

Benign lesion is an umbrella term that may reference any number of non-cancerous lesions of the skin. These lesions may develop on any part of the body with soft tissue. They are classified (named) according to their specific sets of features, where they develop, and other characteristics. Determining if a lesion is non-cancerous requires an accurate diagnosis from a dermatologist.

What Are Cold Sores?

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.

Contact dermatitis is inflammation of the skin that results from direct contact of a substance with the surface of the skin, possibly related to an allergy.

What Are Skin Cysts?

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.

What Is Hidradenitis Suppurativa?

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.

What is Hyperhidrosis?

Hyperhidrosis, often referred to as excessive sweating, occurs when people experience disproportionate and/or unnecessary sweat production. While sweating is a natural function of the body’s systems to keep itself cool and maintain the best temperature, sweating too much or sweating that is not necessary to cool the body can create many difficulties that impact your overall health and wellbeing. Generalized hyperhidrosis may affect the whole body. Others have localized cases of excessive sweating that impact only certain areas. Specifically, there are three main types of localized hyperhidrosis: axillary (impacting the underarms), palmar (impacting the palms), and plantar (impacting the feet). If you experience general or localized excessive sweating at least once per week, you should talk to a dermatologist about a treatment plan.

What Is a Lipoma?

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.

A lipoma is a common, non-cancerous, soft tissue growth just below the skin made up of fat cells. Learn more about lipomas here.

What Is Melasma?

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.

What Are Moles?

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.

What Is Molluscum Contagiosum?

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.)

What Is Psoriasis?

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.

What Is Ringworm?

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.

What Is Rosacea?

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.

What Are Shingles?

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.

What Are Skin Tags?

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.

What Is Sun Damage?

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.

Sunscreen 101

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.

What Is Vitiligo?

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.

What Are Warts?

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.

Understanding Birthmarks & Treatment Options

Birthmarks are common, benign skin conditions, and for the most part, their only negative effect is to mar the cosmetics appearance of the skin. If you or your child have a birthmark that causes you concern, a dermatologist can examine it to ensure it isn’t a more serious skin condition and provide treatment to remove or diminish the appearance of the birthmark. On this page, you can learn more about the different types of birthmarks and the available treatment options.

 

What Is Botox?

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.

What Is Cosmetic Dermatology?

Looking to improve and recover your skin’s youthful appearance?

As we age, our skin naturally loses collagen and elasticity. At the same time, repetitive movements and expressions can create facial wrinkles. In addition to comprehensive medical procedures, dermatologists also provide a wide range of minimally-invasive, low impact treatments designed to address a number of aesthetic desires to help you look and feel your best.

While many conditions from unwanted hair and tattoos to wrinkles and rosacea may not be physically harmful, they can be uncomfortable and even cause emotional distress.

What Are Dermal Fillers?

Loss of facial fullness and volume is one of the many age-related changes that people want to address with their dermatologist. From store-bought topical treatments to advanced dermatologic and surgical procedures, there are numerous cosmetic dermatology treatments available to help restore youthful volume. However, dermal and soft tissue fillers are often the most conservative and impactful solutions to restore volume without undergoing more invasive treatments. There are many different types of dermal and soft tissue fillers, and each one is formulated to address a specific area or issue related to volume loss. You can learn more on this page.

At U.S. Dermatology Partners we offer premier dermatology services for patients of all ages. Book your appointment today to find the best facial filler treatment for you and your skin, using our simple, online scheduling request form.

What Are Keloids?

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.

What Is Keratosis Pilaris?

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.

Understanding Scar Development & How to Address These Skin Flaws

We all want healthy, beautiful skin. But scars, a natural part of the healing process, leave a lasting mark and cause some people to struggle with the negative impact on the appearance of their skin and in some cases, limitations in function or other concerns. If you’re unhappy with the appearance, texture, or health of your skin after an injury, surgery, or other damage that leads to scarring, the U.S. Dermatology Partners team can offer treatment to improve the appearance of scarring.

5 Stars  My first visit, and I was really impressed with her. The last dermatologist I seen for a problem told me I'd have to see a plastic surgeon, but Dr Lyer said she could take care of it right here in her clinic. So I'll be seeing her again soon!! –
