In recent years, plasmacytoid mastitis has become more and more common. Patients with recurrent inflammation of the breast, which is sometimes festering and sometimes healing, have to undergo multiple surgeries, and are often seen in outpatient clinics who have lost their confidence in healing. Plasmacytoid mastitis is a chronic non-bacterial infectious purulent breast disease based on dilated ducts and plasma cell infiltration. It is characterized by the onset of non-lactation or non-pregnancy, often with nipple indentation or overflow, initial lump in the areola, pus ulceration with lipid-like material in the pus, recurrent fistulas, and a mild systemic inflammatory response. The incidence is about 4-5% of benign breast diseases. The actual fact is that you can find a lot of people who are not able to get a good deal on this. Since it is not a bacterial infection, there is no need to use antibiotics, and since it is not cancer, there is no need to remove the breast completely. We use a combination of Chinese and Western medicine (oral plus external post), the drugs are adjusted to the smallest lesion, the least reaction, with surgery, the root of the disease is removed, well. The treatment period is a little longer, about one month. About the key to success or failure of surgery There is an abscess, without incision, can be operated directly. If there is an ulcer with a wound, surgery is possible. The extent of excision is determined before surgery and stained and marked to avoid residue. Only removing the lesion under the nipple and removing the root of the disease can cure it. Only internal reshaping (nipple, gland) can save the shape as much as possible. Negative pressure drainage under the incision, combined with pressure dressing to eliminate the dead cavity Pre- and post-operative, according to the patient’s condition, identification and typing, using different herbs to maintain the efficacy. Comprehensive treatment refers to drug therapy supplemented by physical therapy and external treatment, with the principle of minimal surgical trauma and the goal of one-time cure.
