Synonym: squamous cell carcinoma in situ
Bowen's disease is a form of intraepidermal (in situ) squamous cell carcinoma (SCC) of the skin. It was first described by John Bowen in 1912. Bowen's disease arises in the outer layers of the epidermis and the risk of progression to invasive SCC is relatively low at about 3% for typical cases.
