Metastasizing erythroplasia Queyrat. Report of a case

A typical clinical and histologic case of Queyrat's erythroplasia of the glans penis is presented. For several years the patient had been treated for balanitis and inflammation of the glans. A few months before the patient died, the correct diagnosis was established. Shortly after, metastases to the inguinal lymph nodes were found and treated with X-rays. At autopsy, metastases to other organs were revealed. It is concluded that erythroplasia of Queyrat might be Bowen's disease of a mucosal or mucocutaneous area, and this "carcinoma in situ" may metastasize. Consequently Queyrat's erythroplasia should be treated as a malignant disorder as soon as the diagnosis is established.
