What Is Bowen’s Disease?

This skin disease is considered an early stage squamous cell carcinoma caused by sun exposure. It presents as a gradually enlarging red patch of skin with a distinct but irregular border, and the surface often becomes crusted or scaly. It is rare for people under 30 years old to develop Bowen’s disease, and most affected patients are females over the age of 60 with the lesion(s) on their lower legs.
