Pilonidal Disease and Hidradenitis Suppurativa



  • Pilonidal disease is a subcutaneous infection in the upper half of the gluteal cleft.

  • The acute form is an abscess.

  • The chronic form is a sinus that is an indolent wound resistant to healing.

  • Pilonidal disease is most commonly found in young adults, with increased body hair, in their 20’s.

  • Men outnumber women 3–4 to 1.

  • Occupations associated with the development of pilonidal disease include those in the military, hairdressers, and sheepshearers.

  • Possible predisposing factors include obesity, being a vehicle driver, a sedentary occupation, a history of a furuncle at another site on the body, a deep natal cleft, and a positive family history.

  • The actual incidence is unknown but reported to be 0.7 % in adolescents and 26 per 100,000 in all ages.

  • Pilonidal is not really a “cyst” as no epithelialized wall exits in the cavities this disease creates.
