What Is Breast Inflammation?

The disease is a purulent infection of the breast caused by the invasion of Staphylococcus aureus, most of which occur during lactation, and most of the first mothers. It can occur at any time during lactation, and it is common at 3 to 4 weeks after delivery.

Breast inflammation I. Causes and common diseases:

Breastfeeding: milk accumulation and nipple cracking are common causes.

Non-lactating mastitis (NPM), also known as chronic mastitis, can be divided into specific mastitis and non-specific mastitis according to the cause. The former mainly refers to mastitis caused by specific infections such as tuberculosis, fungi, and parasites. It is rare. The cause is generally clear and the treatment effect is relatively good. The latter mainly refers to granulomatous mastitis and plasmacytosis. Mastitis, subareolar abscess (Zuska disease), lymphocytic sclerosing lobular mastitis, etc., the two most common clinical diseases are granulomatous mastitis and plasma cell mastitis, due to unknown etiology.

Breast inflammation 2. Differential diagnosis:

The diagnosis of acute purulent mastitis is relatively easy. The diagnosis can be made based on breast swelling and pain, body temperature as high as 39 ° C to 40 ° C, and increased blood white blood cell count. If the abscess is deep, the pus cavity is located in the posterior gland space, and the skin is often not obvious. At this time, the puncture is required to extract the pus to confirm. If it is not treated properly, the abscess formation is slow, the local mass does not disappear, the skin is swollen and the systemic symptoms are not obvious, and the chronic inflammation is formed, it needs to be distinguished from other diseases.

Acute mastitis should be distinguished from inflammatory breast cancer:

Acute mastitis usually occurs in a certain section of the breast from the beginning, and inflammatory breast cancer cells extensively infiltrate the reticular lymph vessels of the skin, so the lesions affect most breasts, and the skin has an orange peel-like appearance;

Inflammatory breast cancer can touch a huge lump in the breast, and the skin has a wide range of redness and swelling, but local tenderness and systemic poisoning are mild. Puncture cytology can find cancer cells to confirm the diagnosis.

Breast inflammation

(1) CT examination:

Because CT has a high soft tissue resolution, cross-section scanning without tissue overlap is adopted. The examination method is simple and there are no special contraindications. It has now become a routine inspection method for breast diseases.

(B) B-ultrasound inspection:

The first choice for non-destructive examination is the characteristics of acoustic imaging: Inflammatory mass with unclear boundaries, thickened internal echo, and uneven light spots; Retention of milk, a small dark area without echo; Abscess formation, and the image shows the interior Heterogeneous liquid dark areas, blurred edges, localized thickening of the mass, sometimes stratification, and enhanced echo in the abscess.

(3) Bacteriological examination:

1. Pus smear: Gram-positive cocci can be found by taking pus smear, and acid-fast staining can also be used to check acid-fast bacilli to help determine the type of pathogenic bacteria.

2. Pus culture and drug sensitivity test: guide clinical selection of antibiotics.

3. Blood bacterial culture: When acute mastitis is complicated by sepsis, blood should be drawn once every other day for bacterial culture until negative. The best time to draw blood is to increase the positive rate before a chill or high fever is expected. For those whose clinical manifestations are very similar to bacteremia and have multiple negative blood cultures, the possibility of anaerobic infection should be considered, and blood can be drawn for anaerobic culture.

Breast inflammation IV. Principles of treatment:

Early ultrashort wave physiotherapy can be used; hyperthermia can be treated with infusion, penicillin, cephalosporin antibiotics; acute mastitis to the stage of abscess formation, need timely incision and drainage.
