Sebaceous Cysts: Causes, Treatment, and Recurrence Concerns

Sebaceous cyst

Hello, doctor.
I have two white bumps near my labia, close to the urethra, which look like pus-filled pimples.
I recently had an internal examination at the gynecologist, and the doctor said these are sebaceous cysts resembling comedones.
Can you tell me if a sebaceous cyst is the same as a lipoma or a comedo? The doctor made an incision to drain the pus; will these bumps come back after this? Are these considered tumors? Why do they occur? The doctor mentioned that having more pubic hair may contribute to their development.
After draining the pus, is everything fine, or do I need further tests? P.S.
I have not engaged in sexual intercourse.
Thank you for your response.

Dr. Cao Guotao reply Obstetrics and Gynecology

Hello, sebaceous cysts and acne are quite similar.
Generally, they improve after being squeezed out.
If there is no improvement, it is recommended to visit a hospital and consult a gynecologist.
Wishing you good health.

More Info

Sebaceous cysts, also known as epidermoid cysts, are common benign growths that can occur anywhere on the body, including the genital area. They are typically filled with a thick, yellowish substance called sebum, which is produced by sebaceous glands. These cysts can appear similar to pimples or small lumps and may become inflamed or infected, leading to the formation of pus, which can give them a painful, swollen appearance.

Causes of Sebaceous Cysts
Sebaceous cysts can develop for various reasons, including:
1. Blocked Sebaceous Glands: When the ducts of sebaceous glands become blocked, sebum can accumulate, leading to the formation of a cyst.

2. Skin Trauma: Any injury to the skin, such as cuts or surgical scars, can trigger the formation of a cyst.

3. Genetic Factors: Some individuals may be more prone to developing cysts due to hereditary factors.

4. Hormonal Changes: Hormonal fluctuations, particularly during puberty, can increase oil production and lead to cyst formation.

Treatment Options
The treatment for sebaceous cysts often depends on their size, location, and whether they are causing discomfort or infection. Common treatment methods include:
1. Incision and Drainage: If the cyst is infected or painful, a healthcare provider may make a small incision to drain the pus and relieve pressure. This is what your doctor did when they made a small hole to drain the cyst.

2. Surgical Removal: For larger or recurrent cysts, complete surgical excision may be necessary. This involves removing the entire cyst wall to prevent recurrence.

3. Antibiotics: If the cyst is infected, antibiotics may be prescribed to treat the infection.

Recurrence Concerns
After drainage, there is a possibility that the cyst may recur, especially if the cyst wall was not completely removed. If the cyst is simply drained without excising the entire cyst, it can refill with sebum over time. Factors such as hormonal changes and skin type may also influence the likelihood of recurrence.

Is it a Tumor?
Sebaceous cysts are not tumors in the malignant sense; they are benign growths. They do not pose a significant health risk, but they can cause discomfort or cosmetic concerns. It is important to monitor any changes in the cyst, such as increased size, pain, or changes in color, as these could indicate complications.

Additional Considerations
Your doctor mentioned that having more pubic hair might contribute to the development of these cysts. While this can be a factor, it is not the sole cause. Maintaining good hygiene and avoiding tight clothing can help reduce the risk of cyst formation.

If you have concerns about the cysts returning or if you notice any new symptoms, it is advisable to follow up with your healthcare provider. They may recommend further evaluation or monitoring to ensure that there are no underlying issues.

In summary, sebaceous cysts are common and usually harmless, but they can become problematic if infected or recurrent. Proper treatment and monitoring can help manage any concerns you may have. If you have any further questions or if the cysts continue to cause issues, do not hesitate to seek further medical advice.
