Butt-centric abscesses are ordered by their area in connection to the structures involving and encompassing the rear-end and rectum: perianal, ischioanal, intersphincteric and supralevator. The perianal region is the most incessant and the supralevator the slightest. On the off chance that any of these specific kinds of boil spreads incompletely circumferentially around the rear-end or the rectum, it is named a horseshoe sore.
