Infected Sebaceous Cyst

Infected Sebaceou Cyst

An infected sebaceous cyst is a sebaceous cyst that has become inflamed and filled with pus due to a bacterial infection. It requires medical attention for proper treatment, which may include antibiotics, drainage of the cyst, and wound care.  Whether you're experiencing pain, swelling, redness, or drainage from the affected area, our team is here to help.

Cause of sebaceous cysts

The exact cause of sebaceous cysts is not always clear, but they typically develop due to the following factors:

  • Blocked sebaceous glands: Sebaceous cysts form when the ducts of sebaceous glands become blocked or damaged. This blockage can be caused by an injury, infection, or abnormal cell growth.

  • Hormonal changes: Hormonal fluctuations, such as those that occur during puberty, pregnancy, or menopause, can influence the production of sebum and contribute to the formation of sebaceous cysts.

  • Excessive sebum production: Individuals with naturally oily skin or those who have overactive sebaceous glands may be more prone to developing sebaceous cysts.

  • Hair follicle damage: Trauma or damage to hair follicles, such as from ingrown hairs or skin conditions like acne, can lead to the formation of sebaceous cysts.

  • Genetic predisposition: There may be a genetic component to sebaceous cyst development, as some people may be more susceptible to developing them based on their family history.

It's important to note that attempting to squeeze or pop a sebaceous cyst at home is not recommended, as this can increase the risk of infection or other complications. 

Symptoms of sebaceous cysts

The symptoms of sebaceous cysts can vary depending on the individual and the specific characteristics of the cyst. Here are some common symptoms associated with sebaceous cysts:

  • Visible lump: A noticeable round or dome-shaped lump beneath the skin is a typical symptom of a sebaceous cyst. The size can range from small to medium-sized.

  • Skin texture: The skin over the cyst is usually smooth and may appear normal or slightly yellowish in color.

  • Painless: Sebaceous cysts are typically painless unless they become inflamed, infected, or put pressure on surrounding tissues.

  • Discomfort or tenderness: If the cyst becomes inflamed or infected, it may cause discomfort, tenderness, or mild pain in the affected area.

  • Redness and swelling: Inflammation or infection can lead to localized redness and swelling around the cyst.

  • Drainage: In some cases, a sebaceous cyst may develop a central punctum (a small hole) on the skin's surface, through which a thick, cheesy, or foul-smelling material may occasionally drain.

If you experience severe pain, rapid growth, increasing redness or swelling, signs of infection (such as fever or pus), or if the cyst interferes with your daily activities, it is recommended to seek medical attention. 

Treatment for an infected sebaceous cyst

The treatments involves a combination of medical interventions to address the infection and promote healing. Here are common treatment approaches for an infected sebaceous cyst:

  • Antibiotics: If the sebaceous cyst is infected, your doctor may prescribe oral antibiotics to help clear the infection. It's important to take the full course of antibiotics as prescribed, even if the symptoms improve before completing the medication.

  • Incision and drainage: the cyst may need to be lanced or surgically opened by your doctor to drain the accumulated pus. This helps relieve pain and pressure and allows the infection to heal.

  • Wound care: After drainage, proper wound care is essential. The area should be kept clean and dressed with sterile gauze or a bandage to prevent further infection. 

  • Antibiotic ointment: Applying an over-the-counter antibiotic ointment to the wound can help prevent infection and promote healing. 

  • Follow-up care: It is important to follow up with your doctor to monitor the healing process, ensure the infection is clearing up, and discuss any further treatment or follow-up steps that may be necessary.

It's crucial to seek medical attention if you suspect an infected sebaceous cyst. Infected cysts can worsen if left untreated and may require professional intervention to prevent complications and promote proper healing.
