Bowen disease is a rare skin disorder. Affected individuals develop a slow-growing, reddish scaly patch or plaque on the skin. Sun exposed areas of the skin are most often affected. Bowen disease only affects the outermost layer of the skin (epidermis). Lesions are usually not painful or may not be associated with any symptoms (asymptomatic). In most cases, treatment is highly successful. Bowen disease is considered a pre-cancerous condition, although the risk of developing skin cancer is less than 10 percent. The disorder usually affects older adults. The exact cause of Bowen disease is unknown, although there are identified risk factors such as chronic sun exposure.
Bowen disease was first described in the medical literature by a physician named JT Bowen in 1912. Bowen disease is also known as squamous cell carcinoma in situ, and is generally considered an early, noninvasive form of intraepidermal squamous cell carcinoma. Intraepidermal means that the disease occurs inside the epidermal layer of the skin.
