If you have a hard lump on your buttocks, you should see a specialist in dermatology or a general surgeon?

Hello Doctor, I have a small hard lump on the left side of my buttock, near the groin and close to the coccyx.
It is about the size of a coin.
The surface is reddish and darkened, but it is not on the skin; it is beneath the skin.
It has been on my body for several years.
At first, I didn't pay much attention to it, but it would hurt when I pressed or picked at it forcefully.
However, it usually doesn't hurt and doesn't affect my daily life, so I didn't think much of it.
Recently, while showering, I felt it again, and now that I am more health-conscious, I often worry about it.
I would like to ask the doctor if you have any idea what this condition might be.
I am very concerned that it could be a harmful tumor.
Also, which specialty should I consult? I'm not sure if it should be general surgery, dermatology, or a specialty related to tumors.
Thank you, Doctor, for patiently reading and responding to my concerns.
Sincerely, Xiao Li.

Dear Miss Xiao Li:
1.
There is a hard lump approximately the size of a one-dollar coin located near the coccyx in the gluteal fold.
Common causes to consider include fibromas, lipomas, sebaceous cysts, and abscesses; however, there may also be other rare etiologies.
Given that it has been present for several years, the likelihood of malignancy is low.

2.
It is recommended that you consult with a general surgeon, plastic surgeon, or colorectal surgeon for further diagnosis and treatment.

Hello, 小莉,
Thank you for your detailed description of the lump you have been experiencing. Based on your account, it seems that you have a small hard lump located in the buttock area, specifically near the tailbone, which has been present for several years. The fact that it is not on the surface of the skin but rather beneath it, along with the characteristics you described (redness, tenderness when pressed, and no significant pain during daily activities), raises a few possibilities.

Firstly, it is important to understand that lumps in the body can arise from various causes, including benign (non-cancerous) conditions such as lipomas, cysts, or fibromas. A lipoma is a soft tissue tumor made up of fat cells, which is usually harmless and can be found anywhere on the body. Cysts, on the other hand, are closed pockets of tissue that can be filled with fluid, pus, or other material. They can sometimes become inflamed or infected, leading to tenderness and redness.

Given that the lump has been present for several years without significant changes, it is likely to be benign. However, the recent growth and your increased health awareness are valid reasons to seek medical advice. It is understandable to feel anxious about the possibility of it being a tumor, but it is essential to approach this situation with a clear plan.

To address your concerns, I recommend that you see a healthcare professional who specializes in this area. The most appropriate specialists for your situation would be:
1. Dermatologist: A dermatologist specializes in skin conditions and can evaluate the lump's characteristics, perform a physical examination, and possibly conduct a biopsy if necessary. They can provide insights into whether the lump is a cyst, lipoma, or another skin-related issue.

2. General Surgeon: If the lump requires further investigation or removal, a general surgeon can also be consulted. They are trained to handle various types of lumps and can perform surgical procedures if needed.

3. Oncologist: If there is any suspicion of a malignant tumor, a referral to an oncologist may be necessary. However, this is typically a secondary step after initial evaluations by a dermatologist or surgeon.

In summary, I recommend starting with a visit to a dermatologist. They can assess the lump and determine if any further action is needed, such as imaging studies or a referral to a surgeon. It is essential to communicate your concerns and the changes you have noticed during your visit.
While it is natural to feel anxious about health issues, remember that many lumps are benign and manageable. Early evaluation and diagnosis can provide peace of mind and appropriate treatment if necessary.
Take care, and I hope you find the answers you are looking for soon.

If the goal is simply to obtain a diagnosis, you can make an appointment with either specialty. However, if a diagnosis is confirmed and surgery is being considered due to discomfort from symptoms, you can directly schedule an appointment with general surgery.
