Seborrhoeic Keratosis.

What is seborrhoeic keratosis?

Seborrhoeic keratosis, also known as seborrhoeic keratosis, is a benign skin lesion that often appears with age. It is characterized by scaly, raised patches that can be various shades of brown, black or yellow. These lesions are not malignant and rarely lead to more serious health problems.

Epidemiology and incidence

Seborrheic keratosis is commonly seen in people over the age of 50, although it can also occur in younger adults. It is estimated to affect about 30% of the population at this age, and its incidence increases with age.

Symptoms of seborrheic keratosis

Characteristic of seborrheic keratosis are skin lesions that can resemble waxy, "sticky" growths on the skin. They can appear all over the body, but most commonly on the face, chest, back and shoulders. The lesions are usually painless, but can cause itching or irritation, especially if exposed to friction.

How do you recognize skin lesions?

These lesions are usually oval, with irregular edges and a surface that may look like it is covered with wax. These features help distinguish seborrheic keratosis from other skin lesions.

Causes and risk factors

Although the exact cause of seborrheic keratosis is unknown, genetic factors are thought to play a key role. These lesions are often familial, suggesting the inheritance of a predisposition to their occurrence.

Environmental and lifestyle influences

Environmental factors, such as overexposure to the sun, can contribute to seborrheic keratosis. Lifestyle, including diet and stress levels, can also affect skin conditions.

The role of age and gender

Seborrheic keratosis is more likely to affect older people and is slightly more common in men than in women.

Diagnosis of seborrheic keratosis

The diagnosis of seborrheic keratosis is based mainly on physical examination and visual analysis of the lesion. Dermatologists usually diagnose this disease based on the characteristic appearance of the lesions.

Differentiation with other skin diseases

Although seborrheic keratosis is easily diagnosed, it can sometimes be confused with other skin lesions, such as warts or melanoma. If in doubt, your doctor may order a biopsy to rule out other diseases.

Treatment of seborrheic keratosis

Treatment of seborrheic keratosis is not always necessary, as these lesions are benign. However, if the lesion is irritated or unsightly, various therapeutic options may be considered.

Therapeutic options

• Drug treatment: Some creams can help reduce symptoms, although they do not remove the lesion completely.
• Surgical treatments: Procedures such as cryotherapy, electrocoagulation or spooning can be effective in removing lesions.
• Lasertherapies: Laser therapy is a modern method of lesion removal that offers precise and effective results.

Natural treatments

Some patients seek natural methods, such as the use of essential oils or herbs, but their effectiveness is not scientifically proven.

Seborrheic keratosis removal

Seborrheic keratosis removal is usually a quick and safe procedure. Minor irritation may occur after the procedure, which usually subsides within a few days.

Medical procedures

Removal of skin lesions can be performed in a dermatologist's office, using methods such as cryotherapy or spooning. Each of these procedures has its own advantages and limitations, which are discussed with the patient before the procedure.

Recommendations after the procedures

After the removal of seborrheic keratosis, it is important to take care of the skin by avoiding excessive sunlight and using UV sunscreen creams to help the healing process.

Seborrheic keratosis vs. skin cancer

Seborrheic keratosis are benign lesions that do not develop into cancer. However, if the lesion is unusual or changes rapidly, it is worth consulting a dermatologist to rule out other, more serious skin diseases.

The importance of early detection

Although seborrheic keratosis does not lead to cancer, its early detection allows quick action in case other potentially malignant skin lesions appear.

Preventing seborrheic keratosis

Prevention of seborrheic keratosis focuses on protecting the skin from environmental damage.

Lifestyle tips

• Sun protection: Regular use ofSPFsunscreen, wearing hats and protective clothing can help prevent skin lesions.
• Healthy diet: A balanced diet rich in antioxidants supports skin health.
• Regular checkups: Regular visits to a dermatologist can help detect any changes early.

Seborrheic keratosis in different age groups

Children and adolescents

Seborrheic keratosis rarely occurs in children, but in exceptional cases it can occur at a young age. In such situations, it is particularly important to consult a dermatologist.

Adults and the elderly

Among adults and the elderly, seborrheic keratosis is much more common. Older people may have multiple lesions at the same time, which is normal and usually not a cause for concern.

Summary

Seborrheic keratosis is a common benign skin lesion that appears with age. Although not malignant, its appearance can be unsightly, prompting some patients to seek treatment options. It is crucial to understand that while seborrheic keratosis does not develop into cancer, any skin lesion should be monitored.
