Images of Bowen's disease are available on PCDS.org.uk and AOCD.org. The images for Bowen's disease on these sites show small red, scaly patches on the skin.
Sometimes the patch has crust or oozes a gooey substance, according to the American Osteopathic College of Dermatology. Bowen's disease is also known as "squamous cell carcinoma in situ" and appears on the surface of the skin though it can grow inward, which is more dangerous. Treatment for Bowen's disease usually involves surgically removing the patch or using photodynamic therapy to burn off the area, according to the American Osteopathic College of Dermatology. If treated quickly, the prognosis is excellent.
