With the “ice-breaking” of the national birth control policy, recent years may be a period of high incidence of breastfeeding mastitis and “non-breastfeeding” mastitis, either of which is a “painful” and benign disease. “In the upcoming “second child era”, in order to save you the worries, in order to better prevent and treat the disease, to avoid the pain, I would like to briefly introduce to your friends – granulomatous lobular mastitis, a It is often referred to as “non-lactating mastitis”, a benign disease. It is often misdiagnosed as breast cancer, so we would like to remind you of this. The majority of patients have breastfeeding disorders, such as poor lactation and milk stasis, and others such as hyperprolactinemia, depression, use of schizophrenia medication and emergency contraceptives. The manifestations of granulomatous lobular mastitis 1, mostly in young menstruating mothers, with onset within 6 years after childbirth, and in those who are not married, mostly related to drugs or pituitary lactinomas; 2, mostly breast lumps, with pain, and generally normal body temperature. The disease is intermittent or stage-specific, with some patients breaking down and turning into pus in the later stages, showing yellow water or rice soup-like, bloody pus or bleeding more than pus. 3.Few patients have obvious generalized joint swelling and pain or nodular erythema of lower limbs. 4.There is a tendency of bilateral onset, and about 11% of patients have simultaneous or sequential onset, and the interval is mostly within 1 year. Diagnosis: Patients are mostly in their 30s, children are 2-3 years old, the course of the disease is 2-3 months, the lump is peripheral, first painful and then erythematous, with erythema on the leg, followed by rupture and suppuration. Ultrasonography showed multiple hypoechoic and anechoic, scattered pus cavities and sinus tract formation. Puncture biopsies are sometimes not always detectable depending on the length of onset and timing of biopsy pathology. Treatment of granulomatous lobular mastitis There is disagreement about the treatment of this disease, often anti-inflammatory and anti-TB treatment is not ideal, hormonal treatment is still effective, but it is easy to relapse. Most patients can be cured with the addition of surgical treatment on the basis of TCM identification.
