Invasive vulvar Paget's disease

Seven cases of invasive vulvar Paget's disease are presented. These are compared with 10 cases of intraepithelial vulvar Paget's disease. On the basis of both clinical and histopathologic observations, the concept of intraepithelial vulvar Paget's disease is supported, and this entity is distinguished from the invasive form. Therapy for the latter is discussed.
