A superficial precancerous squamous cell cancer, slow growing (i.e. has not started spreading) skin malignancy.
Red-brown, scaly or crusty patch on the skin that resembles psoriasis, dermatitis or eczema that can occur on any part of the body.
Bowen's disease affects both males and females. Women are affected in the genital area three times as often as men. The disease can occur at any age, but is rare in children.
Causes and symptoms
The exact cause of Bowen's disease is unknown. Like many forms of cancer, long-term sun exposure may be a cause. The skin usually indicates sun damage, such as wrinkling, changes in pigmentation, and loss of elasticity. Ingestion of arsenic has been associated with cases of Bowen's disease found in skin areas unexposed to light or mucous membranes. Human papillomavirus 16 DNA is found repeatedly in Bowen's disease lesions, which suggests that this virus might be a cause. The role of heredity is not well understood. There are cases of Bowen's disease for which a cause cannot be determined.
The symptoms of Bowen's disease include:
- plaque located on or within the skin (intraepidermal)
- open sore that bleeds and crusts and persists for weeks
- wart-like growth that crusts and occasionally bleeds
- persistent, scaly red patch with irregular borders that sometimes crusts or bleeds
- pinkish or brownish raised areas of skin
Bowen's disease can be confused with the other common skin disorders, such as psoriasis or types of dermatitis. Paget's disease of the breast and malignant melanoma are other types of cancer which may be confused for Bowen's disease. A medical history, physical examination, and biopsy establish the diagnosis.
Clinical staging, treatments, and prognosis
Treatment usually involves surgical removal of the lesion. Curettage and cautery methods, which include carbon dioxide lasers, liquid nitrogen, and topical fluorouracil (5-FU) compose the most efficient treatment for management of small solitary lesions.
There can be difficulties with the liquid nitrogen, 5-FU (Efudex, fluoroplex), scraping and burning because Bowen's lesions can hide deep in pores, and cells may extend into the surrounding area where lesion is visible.
Dr. Colin Morton and colleagues at the Western Infirmary in the UK have been developing a photodynamic therapy using topical 5-aminolaevulinic acid(5-ALA).
Dr. Lee and colleagues at the University College of Medicine in Korea have been developing a specially designed radioactive skin patch.
As with most skin cancers, prolonged exposure to the sun can increase the risk of developing the disease.
All treatment options have a recurrence rate of 5 to 10%, and no treatment modality seems superior for all clinical situations.

Laura Ruth, Ph.D.
—General term for abnormally growing (malignant) cells.
—Inflammation of the skin that may be due to an allergic reaction.
—Abnormal growth in melanin cells which are most commonly found in the skin or in the eye.
Paget's disease of the breast
—Cancer of breast nipples which occurs in both men and women. Paget's is characterized by oozy and crusty skin inflammation (dermatitis).
—Common inherited condition that is characterized by reddish, slivery-scaled maculopapules, predominantly on the elbows, knees, scalp, and trunk.
Squamous cell carcinoma
—Type of skin cancer
QUESTIONS TO ASK THE DOCTOR
- How do I know I have Bowen's disease rather than psoriasis, Paget's disease, dermatitis or another skin cancer?
- Is surgical removal of the affected skin area the best treatment?
- What other treatments for Bowen's disease are available other than surgical removal?
