What Is Seborrheic Keratosis?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Seborrheic keratosis (SK) is a common benign skin tumor that typically appears as a brown, black, or light tan growth on the face, chest, shoulders, or back. These lesions are non-cancerous and are often described as having a waxy, scaly, or slightly elevated appearance1 2 3. SKs are among the most frequently encountered benign epithelial tumors in clinical practice, particularly affecting middle-aged and older individuals8.

Causes and Risk Factors

The exact cause of seborrheic keratosis is not well understood, but it is believed to be related to genetic factors and aging. There is no known link between SKs and sun exposure, unlike other skin lesions. They are more prevalent in older adults, suggesting a correlation with the aging process4 9.

Symptoms and Diagnosis

Seborrheic keratoses are usually asymptomatic, but they can sometimes become irritated, itchy, or inflamed. Diagnosis is typically made through clinical examination, and dermoscopy can be used to confirm the diagnosis by evaluating the lesion’s surface characteristics9.

Treatment Options

While seborrheic keratoses are benign and do not require treatment, many patients seek removal for cosmetic reasons or due to discomfort. Various treatment modalities are available, including:

• Topical Treatments: High-concentration hydrogen peroxide solutions, such as A-101, have shown efficacy in clearing SK lesions with a favorable safety profile1 5 8.
• Cryotherapy and Lasers: Cryotherapy, CO2 laser, and Er:YAG laser are common treatments. Lasers, in particular, have been noted for their effectiveness and cosmetic outcomes, although they may cause temporary erythema2 3 4.
• Other Topical Agents: Ammonium lactate and diclofenac sodium gel have been evaluated for their effectiveness in reducing lesion size and improving cosmetic appearance6 9.

Conclusion

Seborrheic keratosis is a benign skin condition that is primarily a cosmetic concern. Various treatment options are available, ranging from topical solutions to laser therapies, each with its own efficacy and safety profile. The choice of treatment often depends on the patient’s preference, the size and location of the lesions, and the desired cosmetic outcome. While SKs are not harmful, their removal can significantly improve the quality of life for those who find them bothersome or unsightly.
