Regarding sebaceous cysts?
Hello, doctor.
I have developed a round lump (approximately 1 cm in diameter) on the outer side of my buttock.
I previously visited a dermatology department at the hospital, and the doctor mentioned it was likely a benign tumor and that it didn't need to be excised.
However, in the past few days, it suddenly became very painful.
I consulted a general surgeon, who indicated that there was inflammation and that the epidermis was nearly broken.
This morning, it ruptured, and a substance resembling ointment oozed out.
I'm wondering if this is what people commonly refer to as an epidermoid cyst? After the white substance drained, the lump has become quite soft in half of its area, and the ruptured part is very painful.
Should I visit a general dermatology clinic, or is it necessary to go to a major hospital? Also, could the white substance lead to an infection in the surrounding skin?

The original physician can continue to provide care; it is not necessary to go to a large hospital.

More Info
Sebaceous cysts, often referred to as epidermoid cysts, are common benign growths that can occur anywhere on the body, including the buttocks. They are typically filled with a substance called keratin, which is a protein found in skin cells. The symptoms you are experiencing, such as the round lump, pain, and the recent rupture of the cyst, are consistent with a sebaceous cyst that may have become inflamed or infected.
Symptoms of Sebaceous Cysts
Sebaceous cysts can present with a variety of symptoms, including:
- A round, movable lump under the skin, often painless unless inflamed.
- Redness and swelling if the cyst becomes infected.
- Pain or tenderness in the area surrounding the cyst.
- The cyst may rupture, leading to the release of a thick, white, or yellowish substance that resembles pus or ointment.
In your case, the presence of pain and the rupture of the cyst, which resulted in the discharge of a white substance, suggests that the cyst may have become inflamed or infected. This is not uncommon, especially if the cyst has been irritated or if there has been friction in the area.
Treatment Options
Treatment for sebaceous cysts can vary based on the symptoms and whether there is an infection. Here are some common approaches:
1. Observation: If the cyst is not causing pain or discomfort, it may simply be monitored over time.
2. Incision and Drainage: If the cyst is painful or has become infected, a healthcare provider may recommend an incision to drain the contents. This can provide immediate relief from pain and pressure.
3. Surgical Removal: For recurrent cysts or those causing significant discomfort, surgical removal may be necessary. This procedure involves excising the cyst and its sac to prevent recurrence.
4. Antibiotics: If there is evidence of infection, antibiotics may be prescribed to help clear the infection.
When to Seek Help
Given that your cyst has ruptured and is causing pain, it is advisable to seek medical attention. You can visit a general dermatologist or a general surgery clinic, as they are equipped to handle such conditions. If the pain worsens, if you notice increased redness or swelling, or if you develop a fever, you should seek immediate medical attention.
Risk of Infection
The discharge from the cyst can potentially lead to infection of the surrounding skin, especially if the area is not kept clean. It is essential to keep the area clean and dry. Avoid touching or picking at the area to reduce the risk of introducing bacteria. If you notice any signs of infection, such as increased redness, swelling, warmth, or pus, consult a healthcare provider promptly.
Conclusion
In summary, it sounds like you are dealing with a sebaceous cyst that has become inflamed or infected. While it may be possible to visit a general dermatologist or a local clinic, if you have concerns about the severity of your symptoms or if the cyst continues to cause problems, visiting a larger hospital may provide you with more comprehensive care. Always prioritize your health and seek medical advice when in doubt.
