Extramammary Pagetʹs disease of the breast: an unusual location with prognostic implications

Extramammary Pagetʹs disease is a neoplastic process of intraepidermal origin; its management and prognosis are very different from those of mammary Pagetʹs disease. We present a case of extramammary Pagetʹs disease located in the breast. This is an exceptional location, whose differential diagnosis is important because of its therapeutic and prognostic implications.
