When to get medical advice

See your GP if you have a persistent red, scaly patch of skin and don't know the cause. It's important to get a proper diagnosis, as Bowen's disease can look like other conditions, such as psoriasis or eczema . If necessary, your GP will refer you to a skin specialist (dermatologist) to determine what the problem is. If they're not sure about the cause, they may need to remove a small sample of skin so it can be looked at more closely (a biopsy ).
