Summarize this article:

To effectively treat breast eczema or an outbreak of psoriasis on your breast, you will likely need a prescription strength corticosteroid product. Topical corticosteroid products, including those available over-the-counter, should not be applied to your breast area without first consulting your physician. Psoriasis outbreaks occur anywhere on the body, including the breast tissue.  Psoriasis patches appear as thick, silvery, sometimes reddened patches, that are itchy and often painful. If you develop a psoriasis outbreak on your breast area, contact your doctor before you apply any medication. Be sure your doctor intends for you to apply medications you may already have on your breast tissue. Breast eczema outbreaks most often occur in the area of the nipple. The area often appears as an itchy, reddened area, and is sometimes accompanied by crusty formations and drainage from the sores. Due to the similarity in the rash associated with breast eczema and a more serious condition, Paget's disease, a medical examination is warranted. Take care to keep the area dry, and avoid harsh soaps or perfumed products. In addition to topical products, your doctor may prescribe oral medications to help treat any infection that may have started, as well as medications that can help control the itching.  Topical products that may be prescribed include corticosteroids that reduce inflammation and promote healing, as well as newer agents, called calcineurin inhibitors. The newer agents are only used in people with severe and repeated flare-ups of eczema. Examples of the newer agents include tacrolimus and pimecrolimus. These agents help your skin to heal, and prevent further flares of eczema or atopic dermatitis. These medications alter the way your immune system works. With outbreaks of both psoriasis and eczema, regardless of where they form on your skin, scratching the areas can lead to complications.  Scratching can cause the condition to spread beyond the immediate area, can cause further skin irritation, and possibly lead to infection. Many people scratch at night without realizing it. Try putting band-aids over your fingertips when you sleep, or sleep with socks over your hands to help avoid scratching.
Make an appointment with your doctor. Identify psoriasis patches. Recognize breast eczema. See your doctor to clarify the diagnosis as breast eczema. Take oral medications. Avoid scratching.
