Seborrheic keratoses are among the most common benign skin growths seen in adults, often developing in the third or fourth decade of life and increasing in number over time. While these lesions are non-cancerous and generally harmless, many individuals choose to have them removed for cosmetic reasons or due to irritation from clothing or jewelry.
At Pacific Plastic Surgery, Dr. Demianczuk offers expert evaluation and treatment of seborrheic keratosis with precision and an aesthetic eye, ensuring minimal scarring and optimal skin appearance.
What is Seborrheic Keratosis?
Seborrheic keratoses are often referred to as “wisdom spots” due to their tendency to appear with age. They can develop anywhere on the skin, including the face, chest, back, shoulders, or scalp. These growths typically have a waxy, rough, or “stuck-on” appearance, and may vary widely in color, ranging from light tan to dark brown or even black. They can affect individuals with light and darker skin tones.
Although seborrheic keratoses are not dangerous and do not turn into skin cancer like actinic keratosis, their appearance can mimic more serious conditions, which is why evaluation by an experienced provider is important.
While seborrheic keratoses are benign, patients often seek removal for a variety of reasons, including:
- Cosmetic concerns, especially on visible areas like the face or neck
- Itching or irritation caused by friction
- Uncertainty about whether the lesion is cancerous
- Bleeding or crusting
- Peace of mind
What Caused Seborrheic Keratosis?
The exact cause of seborrheic keratosis is not fully understood, but several factors appear to contribute to their development. These benign lesions are not contagious, cancerous, or caused by a virus; instead, they are considered a normal part of the skin’s aging process for many individuals.
Common factors that may play a role include:
- Aging: Seborrheic keratoses often begin to appear in individuals over the age of 40 and become more common with time.
- Genetics: There seems to be a hereditary component. If your parents or close family members have seborrheic keratoses, you’re more likely to develop them as well.
- Sun Exposure: Although not a direct cause, chronic sun exposure may increase the number of lesions, especially on sun-exposed areas like the face, chest, and back.
- Skin Friction: Areas of frequent friction, such as under the breasts, on the back, or in the armpits, may be more prone to developing these lesions.
How is Seborrheic Keratosis Diagnosed?
Seborrheic keratosis is typically diagnosed through a visual skin examination performed by a trained medical professional. These growths have a distinctive appearance that is usually easy to recognize, often described as waxy, rough, scaly, or “stuck on”. Their color can range from flesh-toned to deep brown or even black, and they may appear slightly raised or flat.
In most cases, a clinical diagnosis is sufficient. However, if a lesion has an unusual appearance or if there’s any concern that it could be something more serious, such as melanoma or another type of skin cancer, a skin biopsy may be recommended. This involves removing a small portion of the lesion and sending it to a laboratory for microscopic analysis.
How is Seborrheic Keratosis Treated?
Seborrheic keratoses are removed using techniques that prioritize both efficacy and cosmetic outcome. Depending on the size, location, and texture of the lesion, one or more of the following methods may be recommended by Dr. Demianczuk to treat seborrheic keratosis:
Cryosurgery (Freezing)
A probe containing liquid nitrogen is used to freeze the seborrheic keratosis, causing it to gradually fall off. This is a common and well-tolerated method, particularly for smaller lesions.
Electrodesiccation (Electric Cautery)
This technique uses a controlled electric current to gently burn the lesion on the affected skin at the skin’s surface. It’s ideal for raised growths and allows for precise treatment with minimal damage to surrounding tissue.
Surgical Excision
For larger or deeply textured lesions, surgical excision may be the most effective option. The lesion is carefully removed, and the skin is sutured for optimal healing and minimal scarring.
Why Choose a Plastic Surgeon for Seborrheic Keratosis Removal?
While seborrheic keratoses are often treated in dermatology settings, many patients prefer removal by a board-certified plastic surgeon to ensure the best cosmetic result, especially for lesions located on the face or other visible areas. Dr. Demianczuk is skilled in both medical and aesthetic treatment techniques, with a focus on minimizing scarring and enhancing skin appearance.
