From the Guidelines
Acantholytic actinic keratosis should be treated with ultraviolet protection, topical imiquimod, topical 5-fluorouracil, or cryosurgery, as these methods have been shown to be effective in managing the condition and preventing progression to squamous cell carcinoma 1.
Treatment Options
- Topical therapies: 5-fluorouracil (5-FU) applied twice daily for 2-4 weeks, imiquimod 5% cream applied 2-3 times weekly for 4-16 weeks, or ingenol mebutate gel (0.015% for face/scalp applied once daily for 3 days, or 0.05% for trunk/extremities applied once daily for 2 days) are effective treatment options for acantholytic actinic keratosis.
- Cryotherapy with liquid nitrogen is another effective option for isolated lesions.
- Photodynamic therapy may be recommended for extensive or recurrent lesions.
Prevention and Management
- Sun protection is essential for prevention, including daily broad-spectrum sunscreen (SPF 30+), protective clothing, and avoiding peak sun hours.
- Regular skin examinations are important as patients with acantholytic actinic keratosis have increased risk for developing skin cancers, with the acantholytic variant potentially showing more aggressive behavior than standard actinic keratosis.
Considerations
- Treatment should be individualized based on the patient's specific needs and circumstances, taking into account factors such as lesion location, size, and thickness, as well as the patient's overall health and medical history 1.
- Education and patient involvement in their own care are important for effective management of acantholytic actinic keratosis.

From the Research
Acantholytic Actinic Keratosis
- Acantholytic actinic keratosis is a type of actinic keratosis characterized by the presence of acantholysis, which is the loss of intercellular connections between keratinocytes 2.
- Actinic keratosis is a chronic skin disease that can progress to invasive squamous cell carcinoma, and its treatment is crucial to prevent malignant transformation 3, 4.
- The management of actinic keratosis can be divided into lesion-directed and field-directed therapies, with options including cryotherapy, topical creams, and photodynamic therapy 5, 6.
- Acantholytic actinic keratosis may require more aggressive treatment due to its potential for rapid progression to squamous cell carcinoma, although the exact treatment approach may vary depending on the individual case 2, 3.
Treatment Options
- Lesion-directed therapies, such as cryotherapy and excision, can be effective for treating individual lesions 5, 6.
- Field-directed therapies, such as topical creams and photodynamic therapy, can be used to treat large areas of skin with multiple lesions 5, 6.
- Combination therapy, using both lesion-directed and field-directed approaches, may be necessary for optimal treatment outcomes 3, 4.
- Novel therapies, such as resiquimod and betulinic acid, are being investigated for the treatment of actinic keratosis, including acantholytic actinic keratosis 3.
Prevention and Education
- Prevention of actinic keratosis through sun protection and avoidance of UV radiation is essential 6.
- Education on sun exposure prevention and the importance of early treatment can help reduce the risk of malignant transformation 3, 4.
- A high-fat diet may be associated with an increased risk of developing actinic keratosis, and dietary modifications may be beneficial in preventing the disease 6.
