Cyst vs Abscess
Though both abscess and cyst are sac like structures containing fluids enclosed by walls, abscess forms due to an infection or a foreign body, and cyst forms spontaneously. However, if a cyst is infected, it can easily turn into an abscess. Ultrasonically both look the same. This article will talk about both in detail highlighting their clinical features, causes, prognosis, and also the course of treatment abscess and cyst require.
什么是脓肿?
Abscess is a sequel of acute inflammation.Infectionsand foreign bodies may cause an abscess. Acute inflammation is the body’s reaction to injurious agents. Acute inflammation featuresdilatationof blood vessels, increasedcapillary渗透性和液体渗出。血细胞还退出发炎部位的循环。这被称为细胞渗出。细菌分泌的各种化学物质吸引了这些化学物质white blood cellsto the infection site. This is called chemotaxis.Neutrophilsin bacterial infections, eosinophils in parasitic infections andlymphocytesin viral infections reach the inflamed site in abundance. These cells secrete toxic substances that damage the causative bacteria. Oxygen freeradicals,peroxides, superoxides, and digestiveenzymesdamage the surrounding host tissues, as well as invading bacteria, causing massive cell breakdown. Neutrophils remove the cellular debris. When the infection isvirulentthere is extensive tissue damage. When the infection is persistent or virulent, there is continuous pus formation. Dead and dying neutrophils, organisms, cell debris, and fluid exudate are collectively known as pus. Fibrous tissue walls the pus off. This enclosed space filled with pus is called an abscess.
What is a Cyst?
囊肿是带有墙壁的液体腔。囊肿可能发生在体内的任何地方。卵巢囊肿,伪胰囊肿,阴道壁囊肿,输卵管囊肿是一些常见的囊肿。囊肿中的液体不含高蛋白质量。由于液体的积累过多而形成了囊肿。卵巢有很多吸收液体并变成涂鸦卵泡的卵泡。涂鸦卵泡含有一个充满液体的腔。什么时候ovulationdoes not occur, the follicle continues to absorb fluid, and cyst forms.
In the pancreas, when the outflow ducts are blocked,secretionsaccumulate in the glandular parts, to give rise to cyst. There arebenign and malignantcysts.Malignant cysts form due to cancerous cells. When there are cancer cells,almost always there is excessive secretion of fluid, and cysts are the end result. Malignant cysts contain multiple thick half walls inside the cavity partially dividing it into compartments. The outer wall of malignant cysts is normally very vascular. The outer wall may have irregular protrusions. Some malignant cysts secrete specific markers that can be used in the assessment. Malignant epithelial cysts in ovary secrete a chemical called CA-125. Serum CA-125 level is above 35 in malignant cysts.
What is the difference between Abscess and Cyst?
• Cysts form due to excessive fluid secretion while abscess form due to persistent ongoing tissue damage.
• Cyst wall is usually made up of surrounding normal tissue while fibrous tissue makes up the abscess wall.
• There is no regional inflammation in cysts unless infected while abscesses cause regional inflammation.
• Fluid inside cysts has low protein content while abscesses contain pus which is protein rich.
• Cysts disappear spontaneously while abscesses need drainage to accelerate healing.
• Antibiotics promote healing by killing off injurious microorganisms while cysts do not need antibiotics unless infected.
