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 characterised 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

Seborrhoeic keratosis is commonly seen in people over 50 years of age, 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 seborrhoeic keratosis

Characteristic of seborrhoeic 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. These lesions are usually painless, but can cause itching or irritation, especially if exposed to friction.

How do you recognise skin lesions?

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

Causes and risk factors

Although the exact cause of seborrhoeic keratosis is not known, genetic factors are thought to play a key role. These lesions often have a familial occurrence, suggesting an inherited predisposition to their occurrence.

Environmental and lifestyle influences

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

The role of age and gender

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

Diagnosis of seborrhoeic keratosis

The diagnosis of seborrhoeic keratosis is mainly based 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 seborrhoeic keratosis is easily diagnosed, it can sometimes be confused with other skin lesions such as warts or melanoma. If in doubt, the doctor may order a biopsy to rule out other diseases.

Treatment of seborrhoeic keratosis

Treatment of seborrhoeic 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

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

Natural treatment methods

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

Seborrhoeic keratosis removal

Removal of seborrhoeic keratosis is usually a quick and safe procedure. There may be some minor irritation following the treatment, which usually resolves within a few days.

Medical procedures

Removal of skin lesions can be carried out 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.

Post-treatment recommendations

After the removal of seborrhoeic keratosis, it is important to take care of the skin by avoiding excessive sun and using UV filter creams to aid the healing process.

Seborrhoeic keratosis vs. skin cancer

Seborrhoeic keratoses 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 seborrhoeic keratosis does not lead to cancer, its early detection allows quick action if other potentially malignant skin lesions appear.

Prevention of seborrhoeic keratosis

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

Lifestyle tips

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

Seborrhoeic keratosis in different age groups

Children and adolescents

Seborrhoeic 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, seborrhoeic keratosis is much more common. In older people, multiple lesions may occur at the same time, which is normal and usually not a cause for concern.

Summary

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

Tips for patients

• Examine the skin regularly and look out for new lesions.
• Use sun protection to prevent new lesions.
• Consult your dermatologist if you have any concerns.
