A pilonidal cyst is a chronic infection of the skin near the buttocks. It usually occurs near the formation of the crease between the buttocks. This condition results from the body's reaction to hairs which are embedded within the skin. It usually occurs in women between puberty and age 40. Patients who are obese or those with thick body hair also have an increased incidence of pilonidal cysts.
A pilonidal cyst usually presents with pain. The cyst may be a small or a large painful mass. Often the area will drain some fluid which may have a foul odor. When a foul odor is detected an infection is usually present. An infection will also usually have surrounding red skin as well as exquisite tenderness when touched. Clear or bloody fluid may also exude from this area.
Treatment of this problem is surgical. Initial therapy includes identification of the problem as well as antibiotic therapy if an infection is present. If an abscess (a collection of pus which is deeper in the tissues) is present an incision and drainage is required. This will assist resolution of the infection when antibiotics are also used.
Multiple surgical procedures are available for resolution. The exact surgical technique should be discussed with your surgeon.
