What is pus swelling
Forms of inflammation
In principle, all inflammations follow a common pattern, but different forms are differentiated depending on which effects are particularly pronounced.
At serous inflammation the escape of blood plasma and the swelling dominate (e.g. in the case of an insect bite or a cold), usually they heal without consequences.
A purulent inflammation (Pyogenic inflammation) mainly occurs when bacteria such as streptococci or staphylococci are involved.
- When the pus encapsulates itself in a cavity created by the inflammation, an abscess develops. It often leads to severe swelling and is very painful. Encapsulated collections of pus in hair follicles or sebum glands are called boils.
- Pus can also accumulate in existing cavities in the body (empyema), e.g. B. in a joint or in the sinuses.
- There is a particular danger with flat, diffusely spreading purulent inflammations (phlegmon), e.g. B. the orbital phlegmon of the eye socket. You will be treated with antibiotics, and if necessary, the doctor will also remove the pus and dead tissue from the inflamed area.
At proliferative inflammation The new tissue formation overshoots the target and produces too much new, fiber-rich connective tissue (fibrosis). It may limit the function of the affected part of the body.
At granulomatous inflammation Connective tissue cells and anti-inflammatory cells collect and form nodules (granulomas), e.g. B. in tuberculosis.
Ulcerative inflammation (ulcer inflammations) are characterized by the fact that the inflammation "dissolves" the affected tissue - extensive, deep-reaching defects arise in the skin, mucous membranes or inner walls of the blood vessels (e.g. on the intestinal mucosa in ulcerative colitis). These defects will Ulcer (Ulcer) called.
A cyst is a cavity in the tissue that is filled with thin or thick, clear to bloody, purulent fluid. Their contents are held together by an outer skin, the cyst bellows. If an accumulation of fluid is only surrounded by connective tissue, it is called one Pseudocyst.
A minor surgical procedure is often required to remove it. At a Cystectomy (Cyst removal) the cyst and its follicle are removed in one Cystostomy (Cyst opening) on the other hand, the cyst is only opened and emptied.
