Bowen’s disease (BD) (also known as squamous cell carcinoma in situ) is a neoplastic skin disease; it can be considered as an early stage or intraepidermal form of squamous cell carcinoma. It was named after John T. Bowen. (Erythroplasia of Queyrat is a particular type of squamous cell carcinoma in situ which can arise on the glans or prepuce in males and vulva in females and may be induced by HPV.)
