Managing Skin Cysts: What to Do After Popping a Sebaceous Cyst

A sebaceous cyst being squeezed?

I was informed by a doctor at Taichung Veterans General Hospital that I have a lipoma that requires a biopsy.
However, before the biopsy could be performed, a dark object seemed to have been expelled from my back due to pressure while sleeping, leaving a small hole-like area approximately one centimeter in size.
The object was black before being expelled and has lightened in color afterward.
There is no discomfort when I gently touch the area.
What should I do about this situation?

No special treatment is required; a sebaceous cyst typically has an opening, and its contents often flow out after being compressed.

When dealing with skin cysts, particularly sebaceous cysts, it is essential to understand the proper management and care after popping or draining the cyst. A sebaceous cyst, also known as an epidermoid cyst, is a benign growth that can occur when a hair follicle becomes blocked with keratin and sebum. While these cysts are generally harmless, they can become inflamed or infected, leading to discomfort or cosmetic concerns.

In your case, it seems that you have experienced a sebaceous cyst that has been inadvertently popped, resulting in a small opening on your back. Here are some steps to manage the situation effectively:
1. Keep the Area Clean: The first step after popping a cyst is to ensure that the area remains clean. Gently wash the affected area with mild soap and water. Avoid using harsh soaps or scrubs that could irritate the skin further.

2. Avoid Picking or Scratching: It is crucial to refrain from picking at the area or scratching it, as this can introduce bacteria and lead to infection. Even if the area feels itchy or uncomfortable, resist the urge to touch it.

3. Apply an Antiseptic: After cleaning the area, you may apply an antiseptic solution or ointment to help prevent infection. Over-the-counter options like hydrogen peroxide or iodine-based antiseptics can be effective. Ensure that the product is suitable for your skin type and does not cause irritation.

4. Cover the Area: If the opening is significant or if you are concerned about dirt or bacteria entering the wound, consider covering it with a sterile bandage or dressing. Change the dressing daily or whenever it becomes wet or dirty.

5. Monitor for Signs of Infection: Keep an eye on the area for any signs of infection, which may include increased redness, swelling, warmth, pus, or worsening pain. If you notice any of these symptoms, it is essential to seek medical attention promptly.

6. Consult a Dermatologist: Since you mentioned that you have been advised to undergo a biopsy, it is crucial to follow up with your dermatologist. They can assess the cyst and determine whether further treatment is necessary, such as surgical removal or drainage. A biopsy may also be needed to rule out any other underlying conditions.

7. Avoid Future Irritation: To prevent future occurrences, consider wearing loose-fitting clothing that does not rub against the area. If you have a history of sebaceous cysts, discuss preventive measures with your dermatologist.

8. Follow Up on Treatment: If you have been prescribed any topical treatments or medications, be sure to follow your doctor's instructions carefully. This may include the use of antibiotics if there is a risk of infection.

In conclusion, while sebaceous cysts are typically benign, proper care and management are essential to prevent complications. Keeping the area clean, avoiding irritation, and monitoring for signs of infection are critical steps in managing the situation. Always consult with a healthcare professional for personalized advice and treatment options tailored to your specific condition.
