Bowen Disease

Bowen disease is an early form of skin cancer in which abnormal cells are found in the epidermis, the outermost layer of skin. The cells have not usually grown into deeper skin at this stage, but the area still needs medical assessment and treatment. It most often affects adults over 60, particularly on sun-exposed areas such as the face, hands, arms and lower legs. Bowen’s disease, also called Bowens skin cancer in some patient information, is usually treatable when found early.

Bowen disease may look like a minor skin problem and can be mistaken for eczema, psoriasis or an injury that is taking a long time to heal. It often develops slowly as a patch that changes gradually over months or years. The appearance can vary with skin tone and with the area of the body affected.

Bowen disease develops when accumulated DNA damage causes cells in the epidermis to grow abnormally. Ultraviolet radiation from sunlight is the most common driver, although other exposures and health conditions can contribute. Bowen disease is not contagious and cannot be spread through touch or close contact.

Factors that cannot usually be changed

Factors that can be reduced

Bowen disease is usually slow-growing and treatable, but an untreated lesion can enlarge or become irritated and bleed. It can return after treatment, and some people develop additional precancerous or cancerous lesions elsewhere on the skin. In a small proportion of cases, abnormal cells can progress to invasive squamous cell carcinoma, which grows into deeper layers of skin.

A clinician examines the skin patch and considers its size, border, surface, location and how long it has been present. They may ask whether it has changed, bled, crusted or become painful. Because eczema, psoriasis, infection and other skin cancers can look similar, these conditions need to be distinguished before treatment is chosen.

Skin biopsy

A skin biopsy removes a small sample of the affected area for examination in a laboratory. Local anaesthetic is used to numb the skin, and the clinician will explain how to keep the wound clean and covered while it heals. The results can confirm whether abnormal cells are confined to the epidermis or whether invasive cancer is present, helping guide treatment options and follow-up.

Treatment aims to remove or destroy the abnormal cells. A dermatologist may recommend one treatment or combine approaches based on the lesion’s size, number, location, depth, recurrence history and your general health. The options below are examples; the most suitable choice should be discussed with your healthcare team.

Follow your wound-care instructions and protect treated skin from ultraviolet light while it heals. Complete any prescribed topical course, even if the area becomes inflamed, unless your clinician tells you to stop. Attend review if the area does not heal, returns, or develops new changes. Cryotherapy for Bowen’s disease is one option for selected lesions, but it is not suitable for every site or situation.

Sun protection lowers ultraviolet damage but cannot eliminate the risk of Bowen disease, particularly when past exposure or other risk factors are involved. If you have had Bowen disease or another skin cancer, follow your clinician’s plan for regular skin checks and report new or changing areas.

Bowen disease usually has an excellent outlook when treated. The expected outcome depends on the lesion’s size and location, the treatment used, your immune status, and whether testing finds invasive cancer. Ongoing monitoring remains important even after successful treatment.

Check treated areas and the rest of your skin regularly, use sun protection, and attend scheduled dermatology reviews. Follow-up may be especially important after recurrence or for people with immune suppression. Report a new or changing patch rather than waiting for the next routine appointment.

A primary care clinician, dermatologist or skin cancer service can examine the area and arrange a biopsy when needed. Early assessment does not mean the lesion is definitely cancer, but it helps identify Bowens skin cancer and other conditions while they are easier to treat. The same advice applies if you notice signs described as enfermedad de bowen in Spanish-language health information, including a persistent or changing scaly patch.
