Concerns After Wart Laser Removal: Black Spots on Glans Explained - Urology

After undergoing cauliflower laser removal surgery, there are two black patches on the glans?


Hello, doctor.
I would like to ask, after undergoing laser surgery for warts yesterday afternoon, I noticed two black patches on the glans this afternoon.
Could this be due to inadequate coverage of the area with medication after the skin was removed during dressing changes, leading to poor blood circulation and necrosis, or could it be related to vascular circulation issues caused by the anesthesia used during the surgery? It has been approximately 24 hours since the surgery, and there was no noticeable tightness when the dressing was changed after the foreskin retracted, which is why I am very anxious and concerned about the two black areas on the glans.

Hello: If it is located in the cauliflower area, laser treatment should be effective.
If there is bruising from the anesthesia, it should not turn black; if it does turn black, it is likely a few days later.
Wishing you good health.

More Info


After undergoing laser treatment for warts, it is understandable to be concerned about any changes in the appearance of the skin, especially in sensitive areas like the glans. The presence of black spots or discoloration on the glans following laser surgery can be attributed to several factors, and it is essential to understand these to alleviate your concerns.

Firstly, the appearance of black spots can often be a result of bruising or localized bleeding under the skin. Laser treatments can cause some degree of trauma to the tissues, leading to small blood vessels breaking and resulting in a bruise-like appearance. This is particularly common in areas with a rich blood supply, such as the glans. Over time, these bruises typically resolve as the body reabsorbs the blood, and the discoloration should fade.

Another possibility is that the black areas could be related to necrosis, which is tissue death due to a lack of blood supply. This can occur if the area was not adequately protected after the procedure, leading to compromised circulation. However, this is less common, especially if proper post-operative care instructions were followed. If the area was covered and treated as advised, the likelihood of necrosis is reduced.

It is also important to consider the effects of the anesthetic used during the procedure. Local anesthetics can sometimes cause temporary changes in blood flow, but these effects are usually short-lived and should not result in long-term discoloration.

In the first 24 to 48 hours post-surgery, it is crucial to monitor the affected area for any signs of infection, such as increased redness, swelling, or discharge. If the black spots are accompanied by these symptoms, it would be advisable to consult your healthcare provider promptly.

For your peace of mind, I recommend the following steps:
1. Follow-Up Appointment: Schedule a follow-up appointment with your healthcare provider to have the area examined. They can provide a definitive diagnosis and reassurance regarding the appearance of the black spots.

2. Post-Operative Care: Ensure you are following all post-operative care instructions provided by your healthcare provider. This includes keeping the area clean and dry, avoiding any irritants, and applying any prescribed topical treatments as directed.

3. Observation: Keep an eye on the black spots over the next few days. If they begin to change in size, color, or if you experience any discomfort, it is essential to seek medical advice.

4. Avoid Self-Diagnosis: While it is natural to worry, avoid jumping to conclusions about the cause of the discoloration without professional evaluation.

In summary, while the appearance of black spots on the glans after laser wart removal can be concerning, it is often a benign result of the procedure, such as bruising. However, it is always best to consult with your healthcare provider for an accurate assessment and to ensure proper healing. Regular follow-ups and adherence to post-operative care will help in achieving the best outcome.
