Pedunculated seborrheic keratosis is a type of benign skin growth that typically appears as a raised, warty, or flesh-colored lesion on the skin. It is often referred to as a “barnacle of old age” because it is more common in older individuals. Here’s some information about pedunculated seborrheic keratosis, including its causes, appearance, and treatment:
Causes:
The exact cause of seborrheic keratosis is not well understood, but it is believed to be associated with genetic factors and aging. It is not linked to sun exposure or UV radiation, unlike some other skin growths and cancers.
Appearance:
Pedunculated seborrheic keratosis typically presents as a raised lesion attached to the skin by a narrow stalk or peduncle. The appearance can vary, but common characteristics include:
- Color: They are usually flesh-colored, light brown, or dark brown, but they can also be black in some cases.
- Surface: The surface can be rough or warty, and it may appear stuck onto the skin.
- Size: They vary in size, ranging from a few millimeters to a few centimeters in diameter.
- Location: These growths can develop on almost any part of the body, although they are most commonly found on the chest, back, neck, and face.
Treatment:
Pedunculated seborrheic keratosis is typically harmless and doesn’t require treatment unless it causes discomfort, irritation, or if you simply want it removed for cosmetic reasons. Treatment options include:
- Cryotherapy: Liquid nitrogen is applied to freeze and remove the growth. This method is quick and often used for small lesions.
- Excision: The doctor may use a scalpel to cut off the keratosis. This method is preferred for larger growths or if there is concern about the possibility of skin cancer.
- Electrocautery: A special tool that generates an electric current is used to burn off the growth.
- Laser therapy: Lasers can be used to vaporize the keratosis.
- Shave excision: The growth is shaved off using a scalpel or blade.
It’s important to consult a dermatologist or healthcare professional before attempting to remove any skin growth, as a proper diagnosis is necessary to ensure it is indeed a benign seborrheic keratosis and not a more serious skin condition. Additionally, some removal methods may leave scars, so you should discuss your options and preferences with a healthcare provider.
