Recently, many patients with plasmacytoid mastitis have been found, and they basically have similar manifestations: breast lumps that appear suddenly at the age of about 30, not during lactation, accompanied by pain, lumps that develop quickly and grow larger than a duck’s egg in 1-2 weeks, and in some cases, epidermal redness and even ulceration and pus flow. The cause of the onset of plasmacytic mastitis is not very, history of breast surgery, trauma, destruction of the ducts of the breast. The patient has a large accumulation of lipid secretions in the large milk duct behind the nipple and in the surrounding milk ducts, the milk ducts expand and thicken, the accumulated secretions stimulate the local tissues, the body therefore secretes a large number of plasma cells, these secretions overflow from the milk ducts, and an inflammation occurs that is dominated by plasma cell infiltration. Although the disease is “inflammatory”, the majority of patients do not have fever, except when the disease is prolonged and accompanied by other bacterial infections. The following are some of the characteristics of plasmacytosis: 1. Age of prevalence: The disease is most often seen in non-lactating women between the ages of 30 and 50, and has a slow or rapid onset. 2. 2, clinical manifestations: the lesion begins with breast pain may be accompanied by a lump around the areola, the lump is hard or tough in texture. The skin color is red, skin temperature is high, and pressure pain is obvious. The nipple may have a pimple-like discharge with a foul taste. However, when the lesion is slightly distant from the nipple, there may also be no nipple discharge. As the disease progresses, local abscesses may form. The abscess usually communicates with the nipple and forms a fistula. The ipsilateral axillary lymph nodes may be enlarged in patients with long duration of disease. The main symptom of plasma cell mastitis is overflow; some have lumps around the nipples; some have abscesses around the nipples; the abscesses break down on their own or are incised and drained, leaving fistulas that do not heal over time; more often than not, they are good and bad until the breast becomes an indescribably ugly monster! The problem cannot be cured by medication or injections. This is because the cause is not a bacterial infection, but actually an autoimmune disease. To put it bluntly, the organism attacks these acne-like substances in its own body as if they were the enemy. So, without getting rid of these substances that cause allergies, plasmacytoid mastitis will recur. Some patients end up with malignant breast cancer because of years of plasmacytoid mastitis, it’s so not worth it! Chinese medicine has a lot of insights in treating this ailment, however, it still requires oral herbal medicine or herbal replacement on top of surgical removal. However, it is still necessary to take oral medicine or herbal medicine to change the medicine on the basis of surgical excision, which usually takes more than a few months, and the scar is more obvious and the appearance of the breast is worse after healing. Currently, the procedure of “subcutaneous glandular excision with simultaneous implantation of the nipple and areola” has been carried out. In other words, the patient’s nipple and areola are completely preserved and the shape of the breast is symmetrical with the opposite side! While the diseased tissue is completely removed, the appearance of the breast is preserved, and patients no longer have to worry about the lack of breast shape.
