Hemorrhoids? Fistula?


Hello doctor, this is a picture of my buttocks: https://ppt.cc/f18W9x.
There is a growth on the skin that doesn't hurt, itch, or have any wounds; it's just an extra piece that has been there for a long time.
Recently, I went to a dermatology clinic, and they suggested it might be a lipoma, but after researching, it doesn't seem to match the symptoms.
Yesterday, you mentioned it could also be hemorrhoids, but that also doesn't seem to fit.
I would like to confirm what it might be before I find time to address it after the New Year.
Thank you.

The image does not appear to show hemorrhoids or a fistula; if there is no swelling or pain, it does not resemble an anal abscess either.
Fistulas typically present with a hard lump, and there may sometimes be swelling, pain, and discharge.
It is recommended to visit an outpatient clinic for examination, as a digital rectal exam or ultrasound is necessary for a definitive diagnosis.

When it comes to anal issues, distinguishing between hemorrhoids and a fistula can be challenging, especially without a physical examination. Based on your description and the image you provided, it seems you have a growth or protrusion near the anal area that is not painful, itchy, or associated with any wounds. This is a crucial detail that can help narrow down the possibilities.

Hemorrhoids are swollen veins in the lower rectum and anus, which can be internal or external. Internal hemorrhoids are usually not visible and can cause bleeding during bowel movements, while external hemorrhoids can be seen and may cause discomfort, itching, or pain, especially if a blood clot forms. However, if you have a growth that is not painful or itchy, it may not fit the typical presentation of hemorrhoids.

On the other hand, anal fistulas are abnormal connections between the anal canal and the skin near the anus. They often develop after an abscess and can cause symptoms such as pain, swelling, and discharge. Fistulas typically present with more significant symptoms, including pain or discomfort, especially during bowel movements, and may also be associated with pus or blood discharge. Since you mentioned that you do not have any pain or discharge, this may also make a fistula less likely.

Given that a dermatologist suggested the possibility of a fistula, it is essential to consider that they may have seen something indicative of a connection to the anal canal. However, without the classic symptoms of a fistula, it might be worth seeking a second opinion from a gastroenterologist or a colorectal surgeon who specializes in anal disorders. They can perform a thorough examination, possibly including an anoscopy or other imaging studies, to provide a more accurate diagnosis.

In terms of treatment, if it is determined that you have hemorrhoids, treatment options can range from lifestyle changes, such as increasing fiber intake and hydration, to over-the-counter topical treatments. In cases where hemorrhoids are severe or do not respond to conservative measures, procedures like rubber band ligation or surgical removal may be necessary.

If it turns out to be a fistula, treatment typically involves surgical intervention to close the abnormal connection and prevent further complications.
In conclusion, while your symptoms do not strongly indicate either condition, it is crucial to have a professional evaluation to determine the exact nature of the growth. I recommend scheduling an appointment with a specialist who can provide a comprehensive assessment and discuss the best course of action based on their findings. Remember, early intervention can often lead to better outcomes, so seeking medical advice sooner rather than later is advisable.
