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.

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.

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.

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 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.

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.

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.

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.

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.

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.)

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.

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.

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.

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.
