Etiology of Abscess Formation
An abscess is a localized collection of pus resulting from an infectious process, often caused by bacteria such as Staphylococcus aureus. The formation of an abscess occurs due to tissue destruction initiated by an infection, leading to the accumulation of inflammatory cells and necrotic debris.
Gross Features
- Purulent material enclosed by a fibrous capsule
- Central liquefactive necrosis
- Surrounding hyperemic tissue
Microscopic Features
- Presence of neutrophils and macrophages
- Tissue necrosis and fibrin deposition
- Fibrotic capsule formation during chronic abscess development
Complications of Abscess
If untreated, abscesses can lead to systemic infection, rupture causing spread of bacteria, or chronic abscess formation requiring surgical intervention.
