The body's <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/immune.html/">immune system</a> treats the hair as a foreign substance and forms a cyst around it that fills with fluid.</p> <p><img title="illustration" src="https://kidshealth.org/EN/images/illustrations/P-pilonidalCystA-415x233-enIL.png" alt="illustration" name="4955-PILONIDALCYST_A_ENIL.PNG" /></p> <p>Pilonidal cysts may become infected and fill with pus. They can also penetrate deeper in the tissues and form a channel called a sinus tract. A pilonidal cyst might have no visible symptoms other than a small dimple in the skin. Cysts that become infected can be painful, tender, and swollen and may begin to drain fluid or <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/blood.html/">blood</a>.</p> <h3>Keep in Mind</h3> <p>If pilonidal cysts get infected, they can really hurt and should be treated. Treatment depends on how severe the cyst is, but can involve sitz baths, warm compresses, antibiotics, and a minor procedure to incise (lance and drain) the infected cyst, or surgery to clean out the cyst and sinus tract. Surgery is&nbsp;relatively simple, and a person typically heals completely within a few weeks. However, pilonidal cysts can recur (happen again).</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
