Nipple eczema and Paget's disease are both inflammatory conditions that affect the nipple area, but they have different symptoms.
Nipple eczema, or dermatitis, is an inflammation of the skin of the nipples and areola caused by an allergic reaction or irritation. Symptoms include red, scaly, itchy, and sometimes cracked skin on the nipples and areola. The skin may be dry and flaky, and may become cracked and bleed.
Paget's disease is a rare form of cancer that affects the nipple and areola. Symptoms include red or inflamed skin on the nipple and areola, itching, burning, or tingling sensations, and a discharge from the nipple that may be clear, bloody, or contain pus. The skin may also appear crusted, thickened, and scaly. In some cases, the nipple may become inverted.
To differentiate between nipple eczema and Paget's disease, it is important to look for signs of inflammation and changes in the skin of the nipple and areola. Nipple eczema is usually characterized by dry, scaly, and itchy skin, while Paget's disease is usually associated with redness, thickening, and crusting of the skin. Additionally, Paget's disease may also cause changes in the nipple, such as inversion or discharge. If you are concerned that you may have either condition, it is important to seek medical advice to receive a diagnosis and treatment plan.
