It has been reported that some patients have been misdiagnosed with Breast Eczema, when in fact the correct diagnosis in their specific case was Paget's Disease Of The Nipple.
Paget disease of the breast is a rare cancer of the skin of the nipple and areola. It occurs when other breast cancers are already present in the patient and occurs in 1-4% of cases. Malignant cells called Paget cells are found in the skin of the nipple. Symptoms include itching, flaking, crusty skin or around the nipple. A flattened nipple or discharge from the nipple that is yellow or bloody. The early symptoms look similar to many other dermatological skin conditions. It is so rare that is it very easily misdiagnosed.
