  1. Epidemiology
    1. Infection occurs most often in males, age 16 to 30
  2. Predisposing factors
    1. Men
    2. Dark-skin
    3. Hirsutism
  3. Pathophysiology
    1. Pit forms at skin disruption in gluteal fold
    2. Pit plugs with hair and keratin
    3. Abscess forms when drainage of pit is blocked
  4. Symptoms

    2. No systemic symptoms
  5. Signs
    1. Midline tender swelling in gluteal fold over Coccyx
  6. Management
    1. Incision and Drainage under Local Anesthesia
      1. Do not make incision in midline (risk of non-healing)
      2. Make small incision lateral to midline
    2. Consider surgical referral for cyst and sinus excision
