The cytokines trigger an inflammatory response, which draws large numbers of white blood cells to the area and increases the regional blood flow. [ 24 ] The final structure of the abscess is an abscess wall, or capsule, that is formed by the adjacent healthy cells in an attempt to keep the pus from infecting neighboring structures.
Purulent inflammation: Inflammation resulting in large amount of pus, which consists of neutrophils, dead cells, and fluid. Infection by pyogenic bacteria such as staphylococci is characteristic of this kind of inflammation. Large, localised collections of pus enclosed by surrounding tissues are called abscesses.
The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches , staples or sutures .
Microscopically, the cystic space contains necrotic cell debris and macrophages filled with phagocytosed material. The cyst wall is formed by proliferating capillaries, inflammatory cells, and gliosis (proliferating glial cells) in the case of brain and proliferating fibroblasts in the case of abscess cavities. Brain cells have a large amount ...
Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules filled with progeny bacteria. These granules are often called "sulfur granules" due ...
