Should You Remove a Sebaceous Cyst? Risks and Considerations - Dermatology

Sebaceous cyst issues?


I have a sebaceous cyst on my shoulder that has previously been inflamed and has since hardened.
Recently, I consulted with both a general surgeon and a dermatologist, and both advised me to leave it alone.
However, it feels like it has grown to about 1 cm in diameter and seems to be getting slightly larger.
Do I need to have it surgically removed? (I have a congenital heart condition, and I'm concerned that the surgical risks might be increased because of this.)

Hello: A sebaceous cyst is classified as a benign skin tumor.
Generally, surgical excision is recommended in an outpatient setting if there is persistent enlargement, recurrent rupture and inflammation, or for cosmetic reasons.
Thank you!

More Info


When considering whether to remove a sebaceous cyst, particularly one that has previously become inflamed and is now hardening, there are several factors to weigh, especially in light of your pre-existing heart condition.

Understanding Sebaceous Cysts
Sebaceous cysts, also known as epidermoid cysts, are common benign growths that can occur anywhere on the body, including the shoulders. They are typically filled with a substance called keratin and can vary in size. While many sebaceous cysts are harmless and do not require treatment, there are situations where removal may be advisable.


When to Consider Removal
1. Size and Growth: If the cyst is growing (as you mentioned it feels larger than 1 cm), it may warrant further evaluation. Larger cysts can sometimes become uncomfortable or unsightly, leading to a desire for removal.

2. History of Inflammation: Since your cyst has previously been inflamed, there is a risk of recurrence or further complications. Infected cysts can lead to abscess formation, which may require more extensive treatment.

3. Symptoms: If the cyst is causing pain, discomfort, or affecting your daily activities, removal might be the best option.
4. Cosmetic Concerns: If the appearance of the cyst is bothersome to you, this is a valid reason to consider surgical removal.


Risks of Surgery
Given your pre-existing heart condition, it is crucial to discuss the potential risks associated with surgery. Here are some considerations:
1. Anesthesia Risks: Any surgical procedure carries risks associated with anesthesia, particularly for individuals with heart conditions. It is essential to consult with your cardiologist and the surgeon to evaluate your overall health and the specific risks involved.

2. Infection: There is always a risk of infection with any surgical procedure. If the cyst is removed, proper care must be taken to minimize this risk.

3. Scarring: Surgical removal will leave a scar, which may be a concern depending on the location and size of the cyst.

4. Recurrence: While surgical removal is generally effective, there is a possibility that the cyst could recur, especially if it was not completely excised.


Recommendations
1. Consultation: It is advisable to have a thorough discussion with both your dermatologist and cardiologist. They can provide insights into the risks specific to your health condition and whether the benefits of removal outweigh those risks.

2. Monitoring: If the cyst is not causing any symptoms and is stable, your doctors may recommend monitoring it rather than immediate removal. Regular check-ups can help ensure that any changes are noted early.

3. Surgical Evaluation: If surgery is deemed necessary, ensure that the surgical team is aware of your heart condition. They may take additional precautions to ensure your safety during the procedure.

4. Alternative Treatments: In some cases, if the cyst is not causing significant issues, your doctor might suggest alternative treatments, such as corticosteroid injections, to reduce inflammation without surgical intervention.

In conclusion, while many sebaceous cysts do not require removal, your specific situation—particularly the history of inflammation and your heart condition—necessitates careful consideration. Engaging in open discussions with your healthcare providers will help you make an informed decision that prioritizes your health and well-being.

Actually, it's not a big deal to leave it untreated; it won't disappear on its own. If it becomes inflamed, you can consult a doctor then. Whether your condition is severe or mild cannot be diagnosed online, so please discuss it with your treating physician.
