Keratin implantation cyst

Keratin Implantation Cyst is a type of cyst that forms when keratin, a protein found in the skin, hair, and nails, becomes trapped beneath the skin surface. These cysts are benign and are characterized by their firm, round shape and their ability to move freely under the skin. They are commonly found on the fingers, hands, and feet, but can occur anywhere on the body where keratin may become implanted beneath the skin.

Causes

Keratin Implantation Cysts, also known as Epidermoid Cysts or Sebaceous Cysts, are primarily caused by the implantation of keratin due to trauma or surgical procedures. The skin naturally produces keratin as part of its protective barrier, but when an injury occurs, keratin-producing cells can become embedded in the deeper layers of the skin, leading to cyst formation.

Symptoms

The primary symptom of a Keratin Implantation Cyst is a small, round lump beneath the skin. These cysts are typically painless, but can become tender, red, or swollen if infected. In some cases, the cyst may rupture, releasing a thick, yellow substance that is primarily composed of keratin.

Diagnosis

Diagnosis of Keratin Implantation Cysts is usually based on a physical examination. In some cases, a doctor may perform a biopsy to rule out other conditions, such as skin cancer or lipoma. Imaging tests, such as ultrasound or MRI, are rarely needed but may be used to confirm the diagnosis or to examine the cyst more closely.

Treatment

Treatment for Keratin Implantation Cysts is not always necessary, especially if the cyst is small and asymptomatic. However, if the cyst becomes infected or causes discomfort, treatment options may include surgical removal or drainage. Antibiotics may be prescribed if there is an infection. It is important to avoid squeezing or attempting to pop the cyst, as this can lead to further infection or scarring.

Prevention

Preventing Keratin Implantation Cysts involves minimizing skin trauma and maintaining good skin hygiene. Protective clothing and gloves can help reduce the risk of skin injuries, especially in environments where physical injuries are more common.
