Buttock mass
Hello doctor, about 14 years ago I underwent surgery for a fistula, and after the procedure, the nurse administered a painkiller that I believe was called Palonosetron.
Since then, I have had a lump (a hard mass) in my buttocks about the size of a five-dollar coin.
Recently, over the past two to three months, I have been experiencing pain and a tingling sensation in that area.
I am concerned whether this lump could become malignant.
Is there any other treatment besides surgery? Additionally, I have noticed that the shape of my stool has changed to a flat, ribbon-like form.
Could this be related to the hard mass? Thank you.

Understanding buttock lumps can be a complex issue, especially when there is a history of surgery and ongoing symptoms. Based on your description, it seems that you have a lump in your buttock that has been present for many years, and you are now experiencing pain and a sensation of numbness in that area. Additionally, you mentioned a change in your bowel movements, which you are concerned may be related to the lump.
First, let's discuss the potential causes of the lump. Given your history of surgery, it is possible that the lump is a residual effect of the procedure, such as a scar tissue formation or a lipoma (a benign fatty tumor). Other possibilities include a sebaceous cyst, which is a common type of cyst that can occur in the skin, or a hematoma, which is a localized collection of blood outside of blood vessels that can occur after surgery.
The fact that you are experiencing pain and a sensation of numbness could indicate that the lump is pressing on nearby nerves or tissues, which may require further evaluation. It is important to note that while many lumps are benign, any changes in size, shape, or associated symptoms such as pain should be evaluated by a healthcare professional.
Regarding your concern about the lump potentially being malignant (cancerous), it is essential to understand that while most lumps are benign, any new symptoms or changes warrant further investigation. A healthcare provider may recommend imaging studies, such as an ultrasound or MRI, to assess the characteristics of the lump and determine if a biopsy is necessary.
As for the changes in your bowel movements, such as the shape becoming flat or ribbon-like, this can sometimes indicate a problem in the lower gastrointestinal tract. While it may not be directly related to the lump in your buttock, it is crucial to discuss these changes with your doctor. Flat stools can be a sign of an obstruction or other issues in the colon, and it is essential to rule out any serious conditions.
In terms of treatment options, if the lump is determined to be benign and not causing significant issues, your doctor may recommend monitoring it over time. However, if it is causing discomfort or if there are concerns about its nature, surgical removal may be considered.
In conclusion, I recommend that you schedule an appointment with your healthcare provider to discuss your symptoms in detail. They can perform a physical examination, order any necessary imaging studies, and provide you with a clear diagnosis and treatment plan. It is always better to err on the side of caution when it comes to changes in your body, especially with a history of surgery. Your health and peace of mind are paramount, so do not hesitate to seek medical advice.
