Although the term ‘intraepidermal carcinoma’ is often used synonymously with Bowen disease, it is used here in a broader sense to include not only carcinoma in situ of the skin (Bowen’s disease), and penis (erythroplasia of Queyrat), but also intraepidermal epithelioma of Jadassohn, a controversial entity of disputed histogenesis.
Paget’s disease is sometimes included in this category because of the presence of cytologically malignant cells within the epidermis.
