If a sebaceous cyst has just appeared and is small like a comedo and not inflamed, what preventive measures can be taken to remove the sac and prevent it from growing larger?
Hello Doctor, I have discovered two black, open comedones on my back that may have just formed.
They are flat on the surface and small, similar to acne.
Since I have previously undergone surgery for a sebaceous cyst, I recognize that these are cysts and not just comedones, so I have refrained from squeezing or irritating them.
I would like to ask what preventive measures can be taken to remove the cysts to prevent them from growing larger.
I found online that doctors generally say to just observe them as long as they are not growing.
However, I would prefer to take preventive action now that they have just appeared, rather than waiting for them to grow larger before considering surgery.
Thank you.

Hello: It is recommended to consult a nearby dermatologist to see if a small incision can be made locally to completely remove the cyst sac of the epidermoid cyst (sebaceous cyst).
Thank you!

More Info
Sebaceous cysts, also known as epidermoid cysts, are common benign growths that can occur on various parts of the body, including the back. They are typically filled with keratin and can appear as small, round lumps beneath the skin. The presence of black openings on the surface of these cysts indicates that they may be clogged, which can lead to inflammation or infection if not managed properly.
Preventive Measures for Newly Formed Sebaceous Cysts
1. Avoid Squeezing or Picking: As you mentioned, it is crucial not to squeeze or pick at the cysts. This can lead to irritation, inflammation, or even infection. Keeping the area clean and avoiding unnecessary manipulation is essential.
2. Maintain Good Hygiene: Regularly washing the skin with a gentle cleanser can help prevent the buildup of oils and dead skin cells that contribute to the formation of cysts. Using non-comedogenic products can also help reduce the likelihood of clogging pores.
3. Moisturize: Keeping the skin moisturized can help maintain its barrier function and prevent excessive dryness, which may contribute to the formation of cysts. However, be cautious with heavy oils that might clog pores.
4. Use Topical Retinoids: If you are prone to developing cysts, consider using topical retinoids, which can help promote cell turnover and prevent clogged pores. Consult with a dermatologist before starting any new topical treatments.
5. Regular Dermatological Check-ups: Since you have a history of sebaceous cysts, regular visits to a dermatologist can help monitor any new growths. Early intervention can prevent cysts from growing larger or becoming problematic.
6. Consider Excision: If you are particularly concerned about the cysts, discuss with your dermatologist the possibility of excision. While many doctors recommend observation for small, asymptomatic cysts, if you prefer to have them removed before they grow, a minor surgical procedure can be performed. This is often done under local anesthesia and can prevent future complications.
7. Diet and Lifestyle: While there is no direct link between diet and sebaceous cyst formation, maintaining a healthy diet rich in vitamins and minerals can support overall skin health. Staying hydrated and avoiding excessive consumption of processed foods may also be beneficial.
8. Avoid Tight Clothing: Wearing loose-fitting clothing can help reduce friction on the skin, which may contribute to cyst formation. Tight clothing can irritate the skin and lead to clogged pores.
9. Manage Underlying Conditions: If you have any underlying skin conditions, such as acne or oily skin, managing these conditions can help reduce the likelihood of developing cysts. Consult with a dermatologist for appropriate treatment options.
Conclusion
While sebaceous cysts are generally harmless, your proactive approach to preventing their growth is commendable. It is essential to monitor the cysts for any changes in size, color, or symptoms such as pain or discharge. If you notice any concerning changes, or if the cysts become bothersome, do not hesitate to seek medical advice. Your dermatologist can provide tailored recommendations based on your specific situation and skin type. Remember, early intervention is often the key to preventing complications associated with sebaceous cysts.
