blocked milk ducts
Introduction
Introduction The milk duct is blocked, the milk duct itself is inflamed, the tumor and the external pressure are pressed, and the fibers that are shed by the bra can be caused, eventually leading to milk deposition. 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.
Cause
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 the secondary sensation can persist for a long time, the contents of the sac become thicker, and the water in the sac 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.

Diagnosis
Differential diagnosis
Mastitis: Mastitis is an acute suppurative infection of the breast. It is a common disease in the puerperium and one of the causes of postpartum fever. It is most common in breastfeeding women, especially primipara. It can occur at any time during lactation, and the beginning of breastfeeding is most common.
Breast duct dilatation: plasma cell mastitis, referred to as pulp or ductitis, also known as ductal dilatation, Chinese medicine called acne chyle. It is the most common non-bacterial inflammation in non-lactation. In the past few years, we have cured more than 160 cases, indicating that this disease is not uncommon. However, many people, even some surgeons do not recognize this disease, as a general small abscess, repeated incision and drainage, the wound is long-term unhealed, or repeated redness, spontaneous ulceration, formation of fistula, and finally breast Thousands of holes, nipple retraction, distortion.
