Bowen’s Disease is a form of Squamous Cell Carcinoma which is confined to the top layer of the skin. It is characterized by a persistent, non-elevated, red, scaly or crusted plaque with a small potential to turn into an invasive SCC.

 

They can occur anywhere on the skin or mucosal surfaces. The lesions are often small, red, and scaly - and usually present without other symptoms. The surface of the lesion is usually flat, but may become thickened or crusted. Ulceration of the lesion is usually a sign of progression into invasive SCC.

 

Treatments available for Bowen's Disease are very similar to those for solar keratosis: Cryotherapy (freezing), a variety of topical creams, Curettage, Photodynamic therapy, and surgical excision.
