Extra-mammary Paget's disease is an uncommon entity. It has been associated with a underlying sweat gland carcinoma. This paper presents a patient with metastatic endocervical carcinoma and vulval Paget's disease. We believe that the Paget's disease developed as a direct consequence of the cervical tumour. In patients with extra-mammary Paget's disease with no sweat gland carcinoma a careful search to exclude other primary malignant tumours is advised.
