Bowen's disease, also known as squamous cell carcinoma in situ, is a type of skin cancer that affects the upper layer (epidermis) of the skin. It is important to be aware of the symptoms, causes, diagnosis, and treatment options for this condition.
Bowen's disease typically causes reddish or sometimes brown patches on sun-damaged skin, most commonly on the legs. Other areas where patches may appear include:
Head
Neck
Palms of the hands
Soles of the feet
Genital area
Most people develop only one patch, but multiple patches can occur. These patches are usually:
Flat
Larger than a half-inch wide
Scaly, crusty, or oozing
Itchy or sore
The exact causes of Bowen's disease are not fully understood. However, several factors may increase the risk of developing this condition:
Long-term sun exposure
Aging
Arsenic poisoning
Human papillomavirus (HPV) infection (for Bowenoid papulosis)
Bowen's disease can be difficult to diagnose based on appearance alone, as it can resemble other skin conditions such as rashes, eczema, or even melanoma. To confirm the diagnosis, your doctor will typically perform a skin biopsy, which involves taking a sample of the affected skin for laboratory testing.
Treatment for Bowen's disease aims to remove the cancerous cells and prevent the cancer from spreading to deeper layers of the skin. The most common treatment options include:
Surgical excision: The cancerous area and a small margin of surrounding skin are removed.
Mohs surgery: A more detailed procedure for larger patches, involving the removal and examination of thin layers of tissue until no cancer cells are found.
Curettage and electrodessication: The patches are scraped off, and an electric current is used to stop bleeding and destroy any remaining cancer cells.
Topical medications: Fluorouracil or imiquimod may be applied to the skin to slow the growth and reproduction of abnormal cells.
Cryosurgery: Liquid nitrogen is used to freeze and destroy the affected area.
Laser removal: Light energy is used to burn off the cancerous cells.
Photodynamic therapy: Ultraviolet light rays, sometimes in combination with light-sensitizing medication, are used to treat the affected skin.
Radiation therapy: Electrically charged particles (electrons) are used to target and kill cancer cells in the upper layers of the skin.
If you have been diagnosed with Bowen's disease, it is crucial to have regular follow-ups and skin checks with your doctor, as you may be at a higher risk for developing other types of skin cancer, especially if you have a weakened immune system.
