Bowenoid keratosis, often referred to as Bowen's disease (BD), is a form of squamous cell carcinoma in-situ. This means it is an early form of skin cancer where the abnormal cells are confined to the outer layer of the skin (epidermis) and have not yet invaded deeper tissues. According to reference [2], if left untreated, Bowen's disease may progress to invasive squamous cell carcinoma (SCC) in 3-26% of cases.
Understanding Bowenoid Keratosis
Bowenoid keratosis appears as a red, scaly patch on the skin that may resemble eczema or psoriasis. It is typically slow-growing and most commonly develops in sun-exposed areas, such as the face, hands, and lower legs. Although it is not immediately life-threatening, it requires medical attention because of its potential to become invasive.
Key Characteristics of Bowenoid Keratosis:
- Appearance: Red, scaly patch or plaque that is usually flat or slightly raised.
- Location: Most common in sun-exposed areas.
- Growth: Typically slow-growing.
- Potential: Can develop into invasive squamous cell carcinoma if not treated.
Treatment Options for Bowenoid Keratosis
Several treatment options are available for Bowenoid keratosis, focusing on removing the affected tissue and preventing further progression. These treatment methods are primarily ablative, meaning they destroy the abnormal tissue:
| Treatment Method | Description |
|---|---|
| Surgical Excision | Cutting out the affected area of skin, often with a margin of healthy skin around it. |
| Laser Destruction | Using a laser to burn or vaporize the affected tissue. |
| Electrocoagulation and Desiccation | Employing an electrical current to destroy the abnormal cells. |
| Cryosurgery | Freezing the affected area with liquid nitrogen. |
Reference [2] mentions these accepted ablative treatments. The chosen treatment method depends on factors like the size, location, and depth of the lesion, as well as patient-specific considerations.
Conclusion
Bowenoid keratosis is an early, in-situ form of squamous cell carcinoma that requires prompt treatment to prevent invasive progression. Early detection and management can effectively resolve the condition.
