Cysticercosis of udder pigs
Introduction
Introduction to breast cysticercosis Cysticercosis of breast is caused by the larvae of the chain-like aphid (cysticercus) in the subcutaneous or breast tissue of the breast, forming a cystic nodules. This disease is rare in clinical practice, the First Affiliated Hospital of Henan Medical University ( 1980) Analysis of 1100 cases of breast mass biopsy, 5 of which were breast cysticercosis. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: fecal-mouth transmission. Complications: nausea and vomiting
Cause
Causes of cysticercosis in breasts
(1) Causes of the disease
The chain-like aphid eggs are mature when excreted from the feces, containing six hooks, when people eat uncooked pork with worms, or eat vegetables or fruits with chain-like aphid eggs, drink After contaminating the raw water of the eggs of the swine mites, the scorpionfish is oozing into the intestinal wall in the duodenum, and then enters the mesenteric vein and lymphatic circulation, and is transported to the breast to cause the disease.
(two) pathogenesis
Pathologically, the nodules were the size of soybeans, and the cysticercus was milky white. The capsule was filled with liquid. There was a white spot on the wall of the capsule, which was the head section. Its structure was similar to that of adults.
Prevention
Breast cysticercosis prevention
1. Go to the regular meat station to buy quarantine-qualified pork.
2. If you suspect that you have eaten pork that is not cooked or has cysticercosis, you should go to the hospital for physical examination regularly to make early diagnosis and timely treatment.
Complication
Breast cysticercosis complications Complications, nausea and vomiting, coma
Because of the differences in the parasitic parts of the brain, the degree of infection, the time of parasitism, the survival of the worms, and the differences in host reactivity, the clinical symptoms vary from no symptoms to sudden sudden death. The incubation period is from 1 month to 5 years, and the longest period is up to 30 years. The following complications can occur when a transfer occurs:
1, cerebral cysticercosis: complex performance, epilepsy, headache as the most common symptoms, sometimes memory loss and mental symptoms or hemiplegia, aphasia and other neurological symptoms, severe cases can cause increased intracranial pressure, leading to vomiting, Blurred vision, optic nerve head edema, and even coma.
2, subcutaneous and muscular cysticercosis: some patients with cysticercosis have subcutaneous cysticercus nodules. When the cysticercosis is parasitic, submucosal or muscle parasitic, the local sputum and the soy bean are large (0.5-1.5 cm), similar to the cartilage hardness, slightly elastic, no adhesion to the surrounding tissue, can be moved under the skin, the skin A round, or elliptical nodule with no tenderness. The nodules have more trunks, heads and upper thighs. Generally no obvious feeling, a small number of patients have a slight numbness and pain.
3, cysticercosis: accounted for less than 2% of cysticercosis, mostly monocular infection. Cysticercus can be parasitic in any part of the eye, but most of it is deep in the eye, such as vitreous (50% to 60% of cases of cysticercosis)
) and subretinal (28% to 45%). In addition, it can be parasitic under the conjunctiva, in the anterior chamber of the eye, in the eyelids, in the eyelids and in the eye muscles. Located in the lower retina can cause vision loss and even blindness, often one of the reasons for retinal detachment.
4, other parts of cysticercosis: cysticercosis can also parasitize organs such as myocardium or tissue, can appear corresponding symptoms or asymptomatic. But they are all rare.
Symptom
Symptoms of cysticercosis in breasts Common symptoms Subcutaneous nodular lymphadenopathy
Breast cysticercosis often coexists with systemic subcutaneous cysticercosis, the number of breast nodules varies, the size is like soybean, round or oval, smooth surface, medium texture, good activity, no adhesion to surrounding tissues, no obvious tenderness Sometimes it can be accompanied by a swollen lymph nodes.
Examine
Examination of cystic rickets in breasts
1. The pathological biopsy section can be confirmed in the cyst containing the cystic sacral head section.
2. Immunological examination, high sensitivity and specificity.
(1) Indirect hemagglutination test (IHA): The positive rate was 89.6%.
(2) Enzyme-linked immunosorbent assay: the positive rate is 92.9% to 100%.
Diagnosis
Diagnosis and diagnosis of cysticercosis in breast
Diagnostic criteria
1. The patient has a history of intestinal mites, or a mites or gestational plaque found in the feces. It is an important reference for the diagnosis of this disease, and has a history of eating cystic worms.
2. Changes in typical cysticercosis in the breast, especially those with whole body skin nodules.
3. The pathological section of the biopsy can be confirmed by seeing the cysticer's head section.
Differential diagnosis
The disease should be differentiated from breast fibroadenomas, lipomas, and sebaceous cysts.
1. Fibroadenomas: The texture is hard, the mass is located deep in the mammary gland, and the cystic disease nodules are often subcutaneous.
2. Lipoma: The texture is soft.
3. Sebaceous gland cyst: more adhesion to the skin, soft texture, oily spills when squeezed, often easy to make a differential diagnosis.
