a Hard Lump Under the Skin After Circumcision: Blood Clot or Tumor? - Urology

Share to:

There is a protrusion on the skin?


Hello doctor, I had a circumcision almost three weeks ago, and a few days ago I noticed a round, hard lump inside the foreskin.
It doesn't hurt when I gently squeeze it, but it does hurt if I squeeze it hard.
I can move it around under the skin.
Today, I went to see the doctor who performed my circumcision, and he said it was a blood clot and advised me not to touch or squeeze it.
However, I wasn't reassured, so I went to another dermatologist who suggested it might be a tumor and recommended removal for biopsy.
The two doctors have given me different opinions.
Could you please tell me if this is a tumor or a blood clot?

After undergoing circumcision, it's not uncommon to notice changes in the area, including the presence of lumps or bumps. In your case, you have described a hard, round lump that is not painful unless pressed firmly. This scenario raises concerns, especially when you receive differing opinions from two healthcare professionals regarding whether it is a blood clot or a tumor.

Firstly, let's clarify the nature of the lump. After surgical procedures, including circumcision, it is possible for blood to accumulate under the skin, forming a hematoma or blood clot. This is particularly common if there was significant manipulation of the tissues during the procedure. A hematoma can feel firm and may be movable under the skin, which aligns with your description. Typically, hematomas are not painful unless they are pressed hard, as you noted.

On the other hand, the possibility of a tumor, while less common, cannot be entirely ruled out without further investigation. Tumors can also present as hard lumps under the skin, and their characteristics can vary widely. However, the fact that your lump is movable and not consistently painful is more suggestive of a hematoma rather than a malignant tumor.

The differing opinions from the two doctors you consulted can be attributed to several factors. The first doctor, who performed the circumcision, may have a better understanding of the surgical site and the typical healing process. Their assessment that it is a blood clot is plausible, especially if they have experience with post-operative complications. The second opinion from the dermatologist may reflect a more cautious approach, as they may have seen cases where lumps turned out to be more serious.
In terms of management, if the lump is indeed a hematoma, it may resolve on its own over time. The recommendation to avoid manipulating or pressing on the area is sound, as this can exacerbate any bleeding or irritation. Monitoring the lump for changes in size, shape, or pain is essential. If it begins to grow, becomes increasingly painful, or shows signs of infection (such as redness, warmth, or discharge), you should seek further medical evaluation.

If you remain concerned about the lump, it may be beneficial to follow up with a healthcare provider who can perform a physical examination and possibly imaging studies, such as an ultrasound, to assess the nature of the lump more definitively. This can help differentiate between a hematoma and any other potential issues, including tumors.

In conclusion, while the lump you are experiencing is likely a hematoma resulting from your circumcision, it is crucial to keep monitoring it and consult with your healthcare provider if you have any concerns. Open communication with your doctors and seeking a second opinion when necessary is always a good practice in managing your health.
