Milk stasis

Introduction Milk stasis is caused by the leakage of milk from a gland leaf during lactation, resulting in the accumulation of milk in the milk. The main clinical manifestation is the intraductal mass, which is often misdiagnosed as a breast tumor. The initial symptoms are usually breast masses, which are more common on one side. The peripheral part of the breast outside the areola area is round or elliptical. The boundary is clear, the surface is smooth, slightly active, and the cystic nature of the cyst is slightly tender. In 2~3cm, the lymph nodes are generally swollen in the innocent area. Young women find breasts with clear breasts during or after breastfeeding, and complain that they have had mastitis during lactation.

Cause

Etiology and pathology clinically more common breast dysplasia, inflammation, tumor compression, breast glandular or lobular duct epithelial shedding or other substances obstruct the catheter, the milk discharge is not smooth and stagnated in the catheter, causing the catheter to expand to form cysts, cysts Secondary infection can lead to acute mastitis or breast abscess. If there is no secondary infection, it can exist for a long time, the contents of the capsule become thicker, and the water in the capsule can be absorbed over time, and the cyst becomes hard. The wall of the cyst is composed of a thin layer of fibrous tissue, the inner surface is lined with a thin layer of epithelial cells, and some areas even fall off. The inside of the capsule is a light red amorphous structure material and a foam-like cell that phagocytizes milk. A large number of single cells are visible in the interstitial space around the cyst. Infiltration of nuclear cells, epithelial cells, multinucleated giant cells, lymphocytes and plasma cells, small duct dilatation and glandular lobules in lactation can also be seen.

Differential diagnosis

Smooth and tough spherical mass in the breast: one of the characteristics of breast fibroma. Slow growth, the mass is spherical or oval, the surface is smooth, the texture is tough, the boundary is clear, and the touch is slippery. Common in 20 to 25 years old young women, mostly single, slow growth, no symptoms, often inadvertently found in the breast spherical mass.

Breast lumps: A breast lumps usually refer to a disease in which the interior has a mass due to differences in the composition of the breast tissue. Breast lumps are the most common breast disorders, and many benign diseases are also manifested in the form of breast lumps, so the most important aspect of breast lumps is the distinction between benign and malignant. In addition to breast cancer is malignant, breast fibroadenomas, breast hyperplasia, breast cysts, breast fat necrosis and other lumps are benign, can be treated by acupoints and reflex zones massage.
