Paget's disease of the breast

Paget's disease of the breast (also known as mammary Paget's disease) is a rare skin change at the nipple nearly always associated with underlying breast cancer. Paget's disease of the breast was first described by Sir James Paget in 1874. The condition is an uncommon disease accounting for 1 to 4% of all breast cancers cases. 92% to 100% of patients with Paget's disease of the breast have an underlying breast cancer.

The condition in itself often appears innocuous, limited to a surface appearance and it is sometimes dismissed, although it is actually indicative of underlying breast cancer.
