Non-lactating mastitis is not uncommon, with 1-2 cases of non-lactating mastitis out of 20-30 cases seen daily in the outpatient clinics of maternity hospitals. The main common types of non-lactating mastitis are plasma cell mastitis and granulomatous mastitis, both of which are similar in presentation but different in nature. Plasmacytoid mastitis occurs most often in patients with congenital nipple invagination. This is because the metabolic wastes in the breast ducts cannot be eliminated for a long time, and over time, they become numerous and begin to stimulate the body to have an immune response, and a large number of leukocytes (which can be described as a field army) engulf the metabolic wastes and even septicize them, while the predecessor of the leukocytes, plasma cells (which can be described as a reserve force), go forward and come back, accumulating more and more at the breast lesion, if a pathological examination of the focal mass by Bard’s coarse needle aspiration is performed. A large number of plasma cells can be seen under the microscope, so it is called plasma cell mastitis. Granulomatous mastitis is a localized pathological manifestation of systemic inflammation in the breast. Although the etiology is unknown, it is considered to be related to the local distribution of receptors in the breast tissue, such as the abundance of prolactin receptors, and if a focal mass is examined by Bard’s coarse needle aspiration pathology, a large number of granulocytes, phagocytes, lymphocytes and other granulocytes formed around the lobules can be seen under the microscope, so it is named granulomatous mastitis. If you have congenital nipple invagination, please go to the hospital in time to perform nipple invagination correction, Shijiazhuang City Maternity Hospital homemade nipple invagination corrector is simple, inexpensive, can effectively avoid the occurrence of plasma cell mastitis and other breast diseases caused by nipple invagination, if the plasma cell mastitis has occurred, to promptly consult the doctor, and actively perform the complete removal of the mass to prevent the development of the disease. Granulomatous mastitis is a systemic disease, do not rush the treatment process, but in the early stages of the disease, breast lumps do ultrasound can not yet see the hypoechoic dark areas, give coarse needle aspiration of inflammatory mediators, acupuncture injection of trimethoprim, with the appropriate breast treatment equipment and methods, often can be successful conservative treatment, while there is already significant redness and swelling, puncture can be extracted cream-like pus, need to be patient conditioning, and eventually in the condition After stabilization, surgical radical treatment is performed.
