Echinococcosis of the breast
Introduction
Introduction to breast hydatid disease Echinococcosisofbreast, also known as echinococcosis, is a disease in which the hydatid (the worm) parasitizes in the breast tissue. In the human body, the hydatid is parasitic on the liver (70%), in addition to the lungs ( 20% to 30%), other organs such as brain and bone can also be parasitic. Parasitic on the breast is extremely rare. The clinical manifestation is painless mass. In the surgical treatment, cyst rupture can cause planting and should be paid attention to. basic knowledge The proportion of illness: 0.003% Susceptible people: women Mode of transmission: spread by parasites Complications: breast lumps
Cause
Causes of breast hydatid disease
(1) Causes of the disease
In the livestock areas, they are often infected with wild animals, or when they drink raw water or eat vegetables in infected areas.
(two) pathogenesis
1. Pathogenesis: After the vegetables and drinking water contaminated by Echinococcus granulosus are swallowed, the eggs hatch into the six hooks in the stomach and the fingers, and then drill into the stomach wall or the peripheral vein of the intestinal wall, and then enter the portal vein system. Most larvae are blocked in the liver and develop into hydatid sacs. A few can reach the lungs through the central vein of the liver, through the inferior vena cava, and the right heart. The larvae have few chances to invade the blood circulation through the lungs. Therefore, other parts are rare. It is rare in the breast. The larva can reach the subcutaneous tissue of the breast with the blood and lymph, and gradually develop into a granule echinococcosis, and hydatidosis occurs.
2. Pathological morphology
(1) General form: The mass seen is milky white, the texture is slightly hard, the outer part is completely enveloped, the cut surface is cystic, and the inside is a clear colorless liquid.
(2) Histomorphology: under the microscope, the wall of the capsule is composed of fibrous tissue, which may have infiltration of inflammatory cells such as eosinophils, lymphocytes and plasma cells. Inflammatory cells infiltrate the breast tissue around the cyst, and germinal cells are visible on the inner wall of the capsule. Floor.
Prevention
Breast hydatidosis prevention
1. In the epidemic area of hydatid disease, pay attention to food hygiene, do not eat raw meat, do not eat raw vegetables, do not drink raw water.
2. Herders living in epidemic areas of hydatid disease should receive regular quarantine and preventive treatment at epidemic prevention stations.
Complication
Complications of hydatidosis in the breast Complications breast lumps
Breast lumps.
Symptom
Breast hydatid symptoms common symptoms breast lumps breasts huge breast pain
Breast lumps are the main symptoms of the disease, mostly single, but also multiple, no obvious pain and discomfort; the growth of the mass is slow, progressive increase; palpation: the tumor is round or oval, the diameter is more than 3 ~ 5cm; The surface is smooth, the texture is medium, the capsule is sexy, the activity is good, the epidermis has no obvious change, the nipple has no depression, and the axillary lymph node is not swollen.
Examine
Examination of hydatidosis in the breast
1. The complement fixation test is positive in 60% to 70% of patients.
2. The positive rate of the Carson Pione test is up to 90%.
3. Eosinophilia in the blood, but generally not more than 10%, and some can reach 70%.
4. The red blood cell agglutination test can be positive, which is helpful for the diagnosis of this disease.
5. Histopathological examination showed a gray-white mass with a cystic surface and a clear, colorless liquid. Under the microscope, the wall of the capsule was composed of fibrous tissue. There was a germinal layer on the inner wall of the capsule, and inflammatory cells infiltrated in the wall and surrounding tissues.
Breast hydatid disease should avoid cyst puncture, in order to prevent recurrence of hydatid sputum outflow, so it is not suitable for fine needle aspiration cytology.
1. The molybdenum target X-ray film can be seen as a circular or elliptical shape with a neat and smooth "envelope" image.
2. The B-ultrasound shows a typical liquid level reflected wave.
Diagnosis
Diagnosis and diagnosis of hydatidosis in breast
1. Patients with medical history have a history of pastoral life and often have a history of contact with dogs, and there are slow-growing masses in the breast.
2. Palpation There are 1 or several masses in the breast, the diameter can reach 3~5cm, it is round or oval, the surface is smooth, the capsule is sexy, medium hardness and good activity.
3. Auxiliary examination of the pathological section showed a complete envelope with a clear liquid inside; the mammographic X-ray film showed a circular or elliptical shape, and the border was neat and smooth, and the B-ultrasound showed typical liquid level reflection. wave.
