Is a localised collection of pus.

Abscesses start as inflammatory lesions, which then softens and become fluctuant because of the presence of liquefied tissues and the remnants of the inflammatory response.

The only effective treatment for abscesses is drainage (I/D)

Deep abscesses can often be localised and drained under the guidance of ultrasound.
