What Are Actinic Keratoses and How Are They Treated?

TL;DR

Actinic keratoses are rough, scaly spots on sun-damaged skin that can precede skin cancer, particularly squamous cell carcinoma. They develop due to UV-related DNA damage and are treated through methods like cryotherapy and topical medications. Preventative measures, including daily sunscreen use and taking nicotinamide supplements, can reduce their formation.

Key Insights

• 😎 Actinic keratoses are a common skin condition that occurs on sun-damaged skin.
• 😣 Individuals with fair skin and a history of severe sunburn are at a higher risk of developing actinic keratoses.
• 😱 Treatment options for actinic keratoses include destroying the lesions through cryotherapy or electrode desiccation and curettage, or treating a large area with medication creams or photodynamic therapy.

Questions & Answers

Q: What are actinic keratoses and why are they a concern in dermatology?

Actinic keratoses are rough, bumpy spots on sun-damaged skin that can develop into skin cancer. Dermatologists take them seriously because they are a pre-malignancy and can affect the quality of life.

Q: How are actinic keratoses diagnosed?

Actinic keratoses can be diagnosed based on their appearance, but occasionally a biopsy is needed. It is important to consult a healthcare provider or dermatologist for an accurate diagnosis.

Q: What are the treatment options for actinic keratoses?

Treatment options include cryotherapy (freezing the lesions), electrode desiccation and curettage (scraping and burning the lesions), field treatments (treating a large area at once), and photodynamic therapy (using photosensitizing agents and light to kill the abnormal cells).

Q: Can actinic keratoses be prevented?

Wearing a broad-spectrum sunscreen with SPF 50 or greater on a daily basis can help prevent the formation of actinic keratoses. Taking a supplement of nicotinamide has also been shown to reduce the number of lesions formed.

Summary & Key Takeaways

• Actinic keratoses are pre-malignant skin lesions that occur on sun-damaged skin, commonly on areas exposed to sunlight.

• They are caused by DNA damage to skin cells due to exposure to ultraviolet radiation from the sun or tanning beds.

• Multiple actinic keratoses increase the risk of developing squamous cell carcinoma, a type of skin cancer.
