- A skin abscess is better known as a common boil;
- A peritonsillar abscess is a persistent collection of pus behind the tonsils; and
- A perianal abscess is a pool of pus that forms next to the anus, often causing considerable tenderness and swelling in that area and pain on sitting down and on defecating.
