What is the cause of breast echinococcosis?
summary
The disease is prevalent in Ningxia, Qinghai, Tibet, Inner Mongolia and other pastoral areas. Echinococcosis takes dogs as the final host and cattle and sheep as the intermediate host. The adult worm is a dog tapeworm parasitizing on dog intestines, about 3-6 mm in length. The eggs of Echinococcus are excreted with dog feces, polluting pastures, livestock houses, vegetables, soil and water sources. It enters the digestive tract by mouth and infects humans. What is the cause of breast echinococcosis? Let's talk about it
What is the cause of breast echinococcosis?
In animal husbandry areas, it is often infected by contact with wild animals, or ingestion of eggs when drinking raw water or eating vegetables in epidemic areas. After the vegetables and drinking water contaminated by hydatid cyst eggs were swallowed, the eggs hatched in the stomach and twelve fingers to form hexahookworm, then penetrated into the peripheral veins of the stomach or intestinal wall, and then entered the portal vein system.
Most of the larvae are blocked in the liver and develop into hydatid cysts. A few of them can reach the lungs through the central hepatic vein, inferior vena cava and right heart. There is little chance for the larvae to invade the blood circulation through the lungs. Therefore, the involvement of other parts is rare, and parasitism in the breast is rare. The larvae can reach the subcutaneous tissue of breast with blood and lymph, gradually develop into Echinococcus granulosus, and echinococcosis occurs.
The mass was milky white, slightly hard, covered with a complete envelope, cystic in section, and clear colorless liquid inside. Microscopically, the wall of the capsule was composed of fibrous tissue with infiltration of eosinophils, lymphocytes, plasma cells and other inflammatory cells. There were also inflammatory cells infiltration in the breast tissue around the cyst, and germinal layer could be seen in the inner wall of the cyst.
