Pilonidal cyst

Pilonidal cyst

A Pilonidal cyst is a type of skin condition that occurs in the buttock crease or natal cleft. The condition is characterized by the presence of a cyst or abscess that often contains hair and skin debris. It is a common condition that primarily affects young adults, and is more prevalent in males than females.

Causes

The exact cause of pilonidal cysts is not known. However, they are believed to be caused by loose hairs that penetrate the skin. The body considers this hair as a foreign substance, which triggers an immune response. This results in the formation of a cyst around the hair.

Symptoms

The symptoms of a pilonidal cyst may vary depending on whether the cyst is infected or not. An infected pilonidal cyst can cause severe pain, redness, swelling, and drainage of pus or blood. Fever may also occur. A non-infected pilonidal cyst may not cause any symptoms.

Diagnosis

Diagnosis of a pilonidal cyst is usually based on a physical examination. The doctor may also order an ultrasound or MRI to rule out the presence of any other conditions.

Treatment

Treatment for a pilonidal cyst depends on its severity. A small, non-infected pilonidal cyst may not require treatment. However, an infected pilonidal cyst usually needs to be drained. In some cases, surgery may be required to remove the cyst.

Prevention

Prevention of pilonidal cysts involves maintaining good personal hygiene and avoiding prolonged sitting. Regular shaving or hair removal in the area can also help prevent the formation of pilonidal cysts.
