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 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.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
