Breast hamartoma
Introduction
Introduction to breast hamartoma The hamartoma of the breast (hamartomaofmammarygland) is a mixture of adipose tissue, fibrous tissue, mammary duct and mammary gland leaflet. It is a rare type of benign breast tumor. basic knowledge The proportion of illness: 10% Susceptible people: more than 40 years old women Mode of infection: non-infectious Complications: breast lumps
Cause
Cause of breast hamartoma
(1) Causes of the disease
Some scholars believe that the occurrence of this disease has a certain relationship with hormonal changes such as pregnancy and lactation, and it is considered to be the main factor in the occurrence of this disease. From the pathogenesis, it is due to the normal tissue disorder combination in the mammary gland, that is, the residual mammary duct Germ and fibrous adipose tissue develop abnormally and constitute tumor-like malformation. In 1988, when the breast hamartoma was reported in the literature, the cause was that the mammary gland vagus or ectopic, or the abnormal development of the germ part caused the disorder of the normal structural components of the mammary gland.
(two) pathogenesis
1. The location and course of disease:
The disease mostly occurs in the upper quadrant of one side of the breast, and is mainly in the base of the breast, single-shot, more common, and has the growth characteristics of benign tumors, generally in 1 to 3 years, and the development is slow.
2. Pathological changes:
(1) General form: The tumors vary in size, ranging from 1 to 17 cm in diameter. They are round, oblate, and have a capsule. The texture is medium tough, the cut surface is pale yellow, and there is a grayish red color.
(2) Tissue morphology: The tumor is composed of different numbers of mammary epithelial components and mesenchymal components. According to the proportion of epithelial components and mesenchymal components, the tumors are divided into three types: The above skin components are mainly called glandular hamartoma; the fibrous tissue is dominant, called fibrous hamartoma; the adipose tissue is dominant, called glandular pimeloma. ), this is a sign that the disease has its characteristics. The glandular components in the tumor still maintain the function of secreting milk.
Prevention
Breast hamartoma prevention
1. Adequate nutrition, keeping the muscles of the breasts strong and full of fat. Sitting at the side of the line, maintaining a beautiful posture, especially can not contain the chest, should be chest, head up, abdomen, straight knee, so that the beautiful breasts can proudly stand out, women's style fully displayed.
2. Pay attention to protect your breasts from accidental injuries, especially when you are on a crowded bus and teasing children.
3. According to the condition of your breasts, wear a soft, sized bra. I am not a casual person. I am not a human being ! It makes the breasts look good and can be well fixed and supported.
4. Perform self-examination on the breast, regular physical examination of the breast at the specialist, and regular mammography if necessary . When you feel uncomfortable or have problems with your examination, you should seek medical advice promptly to diagnose and treat various breast diseases early.
Complication
Mammary hamartoma complications Complications breast lumps
Hypertrophy of the breast, thickening of the glands outside the upper quadrant of the breast.
Symptom
Breast hamartoma symptoms Common symptoms Breast lumps
The patient inadvertently found a lump in the milk, and the tumor grew slowly. It is more common in the upper left upper quadrant and the left lower inferior quadrant. It can also be located under the breast. The tumor is often single, different in size, round and flat. Round, clear boundary, good movement, generally no tenderness, located in the skin of the breast, soft, very similar to breast lipoma, located in the gland is more solid, like breast hyperplasia or breast fibroadenoma, difficult to preoperative the difference.
Examine
Examination of mammary hamartoma
Fine needle aspiration cytology can sometimes extract milk.
The mammogram of the mammography showed that the density of the breast tissue increased, the structure and shape of the tumor were clear, round or elliptical, the edges were smooth, the boundary was clear, the density of the tumor was uneven, and the outer tissue was tightly wrapped, and the breast tissue was lost. Pointing to the triangular structure of the nipple, the tumor pushes the normal breast tissue to one side, and the low-density area where the X-ray film exhibits uneven density is the characteristic of this disease.
Diagnosis
Diagnosis and diagnosis of breast hamartoma
diagnosis
The diagnosis of this disease is: more than 40 years old women, the tumor is round, oval, with a capsule, soft and uneven, slow growth, sometimes stop growth, X-ray shows on a low-density basis The density is not uniform, and the fine needle aspiration cytology can sometimes extract milk.
Differential diagnosis
The disease needs to be differentiated from breast fibroadenoma and mammary gland hyperplasia. Breast fibroadenoma usually occurs in young women. Breast mass hyperplasia is often multiple, and both breasts are affected at the same time. The tumor has no capsule. If the diagnosis is difficult before operation, At the time, postoperative pathological examination can be identified.
