Plasmacytoid mastitis, also called ductal dilatation, commonly known as ductitis, is referred to as plasmacytosis. Plasma milk is not caused by bacterial infection, but by the accumulation and overflow of fatty material in the ducts, which causes chemical irritation and immune response around the ducts, resulting in a large number of plasma cell infiltrates, hence the name plasmacytosis mastitis. Repeated episodes and fistulas are formed after rupture, which can be followed by bacterial infections that do not heal for a long time. So it is a special kind of inflammation of the breast. The lesions are mostly near the areola and are locally red, swollen and painful. Usually there is no fever. After a few days it can subside on its own, and when the resistance is low due to exertion, cold, etc., it attacks again, but more heavily than once, the lump gradually becomes larger and red, and generally the doctor considers it a small abscess, or uses antimicrobial injections, infusions, and finally incision and drainage, so that a fistula is formed, which is difficult to heal. Sometimes the redness breaks down on its own and also does not heal for a long time. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. However, it should not be too bitter and cold, the more you use cool medicine, the more the lumps do not disappear. (1) hormone oral dexamethasone, or prednisone treatment, gradually reduce the amount, with anti-inflammatory drugs oral anti-inflammatory treatment. (2) At the same time, Chinese herbal medicine oral warming Yang to resolve phlegm, swelling and dispersion. (2) Use warming medicine in the chronic period. 3. Choosing the best time for surgery is most important. The interictal period, i.e. the wound healing period, is the best time for surgery, but some people think that what surgery is done when the disease is well? Wait until the redness and swelling again, broken, so delayed a long time. (1) During the attack, you can take topical Chinese medicine to relieve pain if necessary. (2) At the same time with cephalosporin static drip anti-inflammatory, during the period of rupture, actively change the medicine, or take the hanging thread therapy. If the wound can not heal, wait for the acute inflammation to subside, the wound is most superficial when the surgery, when there is the possibility of infection after surgery. 4. The key to successful surgery is to flip the areola, remove the lesion thoroughly and clean all traumatic surfaces. Treatment depends on the different clinical manifestations, but the main point of treatment is to surgically remove the diseased breast ducts in order to achieve complete eradication. The lump may be excised in the case of a limited mass, an incision may be made to drain the pus if an abscess is present, and the fistula may be removed if a fistula is present. In some cases, a unit mastectomy may be considered for most chronic fistulas or severe breast deformities that are too long in duration.
