Seborrheic Keratoses

Among the most common skin disorders is Seborrheic Keratoses (Scleroderma), a chronic, inflammatory skin condition that affects the skin, mainly on the face and scalp. It can be painful and can result in discoloration. There are several treatments available, depending on the cause and the severity of the condition. There are also some steps you can take to prevent it from occurring.


Whether they are small or large, seborrheic keratoses can be a cosmetic problem. They can become unsightly and cause itching, rashes, and friction-induced irritation. When they cause discomfort, you may want to have them removed. There are many ways to treat seborrheic keratoses, including cryotherapy and electrosurgery.

Seborrheic keratoses are benign skin growths that are found on the epidermis. They are often waxy or raised, and they can be tan or brown in color. They are not contagious, and the majority of patients don’t need treatment. However, there are times when you might have a larger number of them, and you may want to have them examined by a doctor.

If you have a lot of seborrheic keratoses, you may be referred to a dermatologist. They can remove the growths and do testing to determine the cause of your condition. This may include a skin biopsy. They can also determine whether you have a malignancy, and they may recommend other treatments if you have a high suspicion of malignancy.

Seborrheic keratoses usually appear in middle-aged and older people, but they can also appear in younger people. They appear as warty growths, and they are often seen on the neck, back, and torso. They are usually round or oval, and they can be raised or flat. The surface of the growths is a brownish yellow or a light tan. They can be itchy or painful, and they can cause bleeding.

The best way to tell if you have seborrheic keratoses is to look at them closely. You can do this by using your fingers, or by looking at them under the microscope. They are usually round, oblong, or rectangular in shape, and they can have a waxy, crusty, or scaly appearance. They are sometimes tan, but they can also be white, black, red, or yellow.

If you have several seborrheic keratoses, or if you have a sudden increase in them, you should see a doctor. These may be signs of an underlying malignancy, and they may be a symptom of colon cancer.


Usually, the diagnosis of seborrheic keratoses is made by examining the patient’s skin. The lesions are found on the trunk, chest, or neck. They may have a waxy appearance. They can range in size from a few millimeters to a few centimeters. They can appear round, oval, or flat. They can appear dark, light brown, or tan. They are typically not contagious.

Although the exact cause is unknown, seborrheic keratoses can be confused with squamous cell carcinomas, malignant melanoma, or precancerous skin lesions. In some cases, the lesions can become larger and develop rapidly.

In most cases, the onset of the lesion occurs in later adulthood. However, in people with a history of skin cancer, the growth may appear suddenly.

A new diagnostic test for SK has been developed. It does not require a skin sample. It allows physicians to perform a confocal microscopic examination of a small patch of the patient’s skin. This method has been proven highly effective in identifying SK.

Generally, the skin lesions will heal on their own. However, patients may wish to have them removed to prevent future growth. A variety of methods can be used to remove seborrheic keratoses. Some are surgical, while others are cosmetic procedures. The treatment depends on the patient’s needs.

In many cases, a simple curettage will be sufficient to rid the patient of seborrheic keratoses. In some cases, it will be necessary to take a sample for histological examination. This procedure can be performed after local injection of lidocaine. The mark can then be shaved off. It is important to keep in mind that the affected area will often blister. If this happens, the wound will need to be treated with an antibiotic. The patient will be asked to return for a follow-up appointment to check the healing process.

During a consultation, the dermatologist will examine the skin growths to determine their presence and location. During the examination, the doctor may place a dressing to prevent an infection. The doctor may also prescribe an antibiotic. If the growths continue to recur after removal, the doctor will consider the growths to be a sign of skin cancer.

Treatment options

Unlike skin cancer, seborrheic keratoses are benign growths that appear on the surface of the skin. They are usually brown or black and tend to be raised above the skin. They may have a waxy, velvety appearance, and can resemble warts. They are not contagious, though they can be cosmetically unattractive.

There are many treatment options for seborrheic keratoses. These treatments include curettage, electrosurgery, and cryosurgery. Depending on the severity and location of the growth, your healthcare provider will recommend the best course of action.

Electrosurgery uses an electric current to burn away the growth. This method can produce slight scarring, but the risk is very low. If the entire growth is not removed during the first procedure, the doctor will repeat the procedure. If the growth is too large, curettage may be a better option.

Another type of treatment involves freezing the growth with liquid nitrogen. This will cause the growth to harden, but it will eventually fall off. This may not be a good option for thicker or irregularly shaped seborrheic keratoses.

Surgical removal of seborrheic keratoses is also an option. This type of surgery is performed by a dermatologist. This is a minor procedure that doesn’t involve stitches. During this process, the growth is scraped off, and a sample is sent to the lab for analysis.

The use of topical hydrogen peroxide has been FDA-approved for treating seborrheic keratosis. However, this solution can cause skin irritation. If your doctor recommends this treatment, you should discuss the risks and benefits of it with your health care provider.

If you’re worried that you have seborrheic keratoses, talk with your health care provider to see which treatment will work for you. Your provider can guide you through the process, but it’s important to remember that some treatments can be painful or cause scarring.

It’s important to get the seborrheic keratoses treated quickly. In addition to cosmetic concerns, the growth can be uncomfortable and could be a sign of a more serious problem. If you have a family history of these skin cancers, or if you’ve had a lot of sun exposure in your life, you should consider having them checked out by a physician.


Several factors may play a role in the prevention of seborrheic keratoses. These include skin friction and exposure to ultraviolet light. People with a family history of these skin growths have an increased risk of developing them.

Symptoms of seborrheic keratoses may include itchiness, bleeding, and irritation. Often, they appear on the face and arms, but they can also appear on the trunk, chest, and mucous membranes. They can look like warts or skin tags and range in color from brown to black.

Some types of keratoses are caused by a virus called human papillomavirus. In most cases, the growths are benign and do not become cancerous. If multiple lesions appear, a biopsy may be necessary to confirm the diagnosis.

The best way to prevent seborrheic keratoses is to avoid excessive sun exposure. These growths are commonly found in older adults, but they are also seen in younger people. It is not known why some people are more prone to them than others. However, some researchers believe that long-term exposure to sunlight plays a part.

Occasionally, seborrheic keratoses are mistaken for skin cancer. In these cases, a dermatologist will remove the growth for testing. In some cases, a healthcare professional will use liquid nitrogen or electrosurgery to treat the problem. These techniques are cosmetic, but will not be covered by insurance.

If your keratoses are large and hard to remove, your healthcare professional may recommend shaving excision. This procedure is performed by using a curette to cut the growth away.

Chemical peels are also used to remove these growths. Trichloracetic acid is used in a solution to dissolve the growths. If you are worried about the risks of scarring, you can also apply concentrated hydrogen peroxide, but you should be extremely careful.

If you have multiple seborrheic keratoses, you may be at high risk for other types of cancer. You should call your health care provider if you experience any symptoms. It is important to discuss your condition with a physician to determine the best course of action.

Seborrheic keratoses can be removed, but they usually do not reappear. They are not contagious.
