Acanthotic seborrheic keratosis, also known as seborrheic keratosis, is a non-cancerous (benign) skin tumor that commonly affects older individuals. It is one of the most common types of benign skin lesions. Here’s some information about its causes, appearance, and treatment:
Causes:
The exact cause of seborrheic keratosis is not well understood. It is believed to be related to genetic factors, as it often runs in families. Ultraviolet (UV) radiation from the sun may also play a role in their development. While the precise cause is not known, seborrheic keratoses are not linked to skin cancer and are considered harmless.
Appearance:
Seborrheic keratoses typically appear as raised, brown, black, or tan growths on the skin. They are often waxy or scaly in texture and can vary in size from a few millimeters to several centimeters in diameter. The lesions are usually round or oval-shaped and have a well-defined border. They can appear on various parts of the body, including the face, neck, chest, back, and extremities. The color and appearance of these growths can vary, but they are usually not painful.
Treatment:
Seborrheic keratoses are typically benign and do not require treatment unless they become irritated or are cosmetically bothersome. If treatment is desired, several options are available:
- Cryotherapy: Liquid nitrogen is applied to freeze and remove the growth. This is a common method for removing seborrheic keratoses.
- Curettage and Electrocautery: The growth is scraped off with a curette (a sharp, spoon-like instrument) and then cauterized with an electrical current.
- Laser Therapy: Lasers can be used to vaporize the growth. This method is often used for smaller seborrheic keratoses.
- Topical Medications: In some cases, topical creams or ointments containing ingredients like retinoids or alpha hydroxy acids may be prescribed to help reduce the appearance of seborrheic keratoses, although they may not completely remove them.
It’s important to note that seborrheic keratoses are typically harmless and do not require treatment unless there is a specific medical reason to remove them. If you notice any changes in the appearance of a skin growth, or if you’re unsure whether a growth is a seborrheic keratosis, it’s advisable to consult a dermatologist for a proper evaluation and diagnosis. Additionally, it’s essential to practice good sun protection and maintain regular skin checks for any suspicious or changing skin lesions to detect and address potential skin cancer early.
