Clonal seborrheic keratosis, also known as seborrheic keratosis (SK) or senile wart, is a common benign skin growth that typically occurs in middle-aged or older individuals. They are non-cancerous and do not pose any serious health risks. Here’s some information about clonal seborrheic keratosis:
Causes:
The exact cause of seborrheic keratosis is not well understood, but they are believed to result from a combination of genetic factors and aging. They tend to run in families, suggesting a genetic predisposition. Sun exposure may also play a role in their development, as they are more common on sun-exposed areas of the skin.
Appearance:
Seborrheic keratoses can vary in appearance but typically have the following characteristics:
- Color: They are often tan, brown, black, or sometimes flesh-colored.
- Texture: They are usually raised and have a waxy, scaly, or slightly rough surface. They may resemble a stuck-on or pasted-on lesion.
- Size: Their size can range from a few millimeters to several centimeters in diameter.
- Shape: They can be round or oval and may have a well-defined border.
- Location: They commonly appear on areas of the skin that are exposed to the sun, such as the face, neck, chest, back, and shoulders, but they can occur anywhere on the body.
- Quantity: Multiple seborrheic keratoses can develop, and they often increase in number as people get older.
Treatment:
Clonal seborrheic keratoses are typically harmless and do not require treatment unless they become irritated, itchy, or if there is concern about their appearance. In such cases, treatment options include:
- Cryotherapy: Freezing the seborrheic keratosis with liquid nitrogen, causing it to fall off over time.
- Electrocautery: Using an electrical current to burn off the growth.
- Curettage: Scraping the growth off with a special instrument.
- Laser therapy: Using a laser to vaporize the keratosis.
- Shave excision: A doctor may use a scalpel to shave off the growth.
It’s important to note that even with treatment, new seborrheic keratoses can develop in other areas. If you notice any changes in the appearance of these growths, such as bleeding, rapid growth, or an irregular border, it’s essential to consult a dermatologist to rule out any concerning conditions, as they can sometimes be mistaken for more serious skin lesions like melanoma. Regular skin checks and professional evaluation are crucial for maintaining skin health.
