Sebaceous cyst

What is Sebaceous cyst

A sebaceous cyst is a noncancerous growth that can develop under the skin. It is usually filled with a thick, yellowish material called sebum, which is a natural oil produced by the skin's sebaceous glands. Sebaceous cysts can develop anywhere on the body, but they are most commonly found on the face, neck, back, and chest. They are usually harmless and do not require treatment unless they become inflamed, infected, or cause discomfort.

Symptoms of Sebaceous cyst

The symptoms of a sebaceous cyst can vary depending on the size and location of the cyst. Some common symptoms include:

  1. A small, round bump under the skin

  2. Skin discoloration over the bump

  3. A foul-smelling, cheese-like substance that may drain from the bump

  4. Pain or discomfort if the cyst becomes inflamed or infected

  5. Redness or tenderness around the bump

  6. An increase in the size of the bump over time

It is important to note that not all sebaceous cysts cause symptoms, and some may go unnoticed if they are small and located in an inconspicuous area. If you notice any changes in the appearance or size of a bump on your skin, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Causes of Sebaceous cyst

Sebaceous cysts are typically caused by a blockage or damage to the sebaceous glands, which are the oil-producing glands in the skin. Some common causes of sebaceous cysts include:

  1. Hormonal changes: Changes in hormones, such as during puberty, can cause an increase in sebum production and lead to the formation of cysts.

  2. Trauma: Injuries or damage to the skin can cause a blockage in the sebaceous glands, leading to the formation of cysts.

  3. Genetics: Some people may be more prone to developing sebaceous cysts due to their genetics.

  4. Medical conditions: Certain medical conditions, such as acne or basal cell nevus syndrome, can increase the risk of developing sebaceous cysts.

  5. Certain medications: Long-term use of steroids or other medications that affect hormone levels can increase the risk of developing cysts.

While sebaceous cysts can develop for a variety of reasons, they are usually harmless and do not require treatment unless they become inflamed, infected, or cause discomfort.

Treatment

Sebaceous cysts typically do not require treatment unless they become inflamed, infected, or cause discomfort. In these cases, treatment options may include:

  1. Incision and drainage: A healthcare professional can use a sterile needle or scalpel to make a small incision in the cyst and drain the contents. This can help relieve discomfort and reduce the risk of infection.

  2. Removal: If the cyst is large, painful, or recurrent, a healthcare professional may recommend surgical removal. This involves making an incision in the skin and removing the entire cyst, including the sac. This procedure is typically performed under local anesthesia on an outpatient basis.

  3. Injection: In some cases, a healthcare professional may inject a corticosteroid medication into the cyst to reduce inflammation and shrink it.

It is important to note that attempting to squeeze, pop, or puncture a sebaceous cyst at home can increase the risk of infection and may cause the cyst to return. It is recommended to seek medical advice before attempting any home remedies or treatments.
