Redness and Peeling in the Coronary Sulcus: Causes and Solutions - Urology

Erythema and desquamation of the coronal sulcus?


Hello Dr.
Du, at the beginning of the year, after having safe sexual intercourse with my girlfriend, I experienced a stinging sensation.
While showering, I pulled back my foreskin to clean and noticed redness, swelling, and a stinging sensation in the area of the corona, along with some discharge.
I later went to the hospital for an examination, and the doctor informed me that I might have phimosis and advised me to maintain regular hygiene (the glans is exposed when not erect, and the foreskin retracts automatically when erect).
I was prescribed a topical antifungal cream.

It has been six months without sexual activity, and I masturbate about three times a week.
I wash and rinse the area with water every day or every other day, use a hairdryer to dry it, apply the cream, and then cover the foreskin again.
However, there has been no improvement.
Recently, I noticed that the previously red and swollen area has become even redder, and there are new slightly red areas.
The new slightly red areas occasionally itch.
I plan to return for another examination next week.

Could you please advise me, Dr.
Du, on what this issue might be? I have never experienced anything like this before, and I have never engaged in unsafe sexual practices.
Is it possible that I am applying the medication incorrectly? Thank you very much.

Hello: For general cleaning of the foreskin, it is sufficient to wash with water and dry it without using soap.
After urination, make sure to dry it to keep it clean and dry.
There is no need for ointment at this time.
During sexual activity, always use a condom, and there is no need for a hairdryer.
If it does not improve within one to two weeks, seek medical attention.
If parents have diabetes, inform the doctor and check blood sugar levels.
Wishing you good health.

Hello! Thank you for reaching out with your concerns regarding the redness and peeling in the coronary sulcus area. Based on your description, it sounds like you may be experiencing a condition that could be related to several factors, including hygiene practices, skin irritation, or even an underlying infection.

The coronary sulcus, which is the groove located at the base of the glans penis, can become irritated for various reasons. One common cause is inadequate hygiene, especially if there is a buildup of smegma, which is a combination of dead skin cells, oils, and other bodily secretions. This can lead to inflammation and infection, resulting in symptoms such as redness, swelling, and discharge. It's good that you are taking steps to maintain cleanliness by washing the area regularly, but it’s essential to ensure that you are doing so gently to avoid further irritation.

Another possibility is that you may be experiencing a form of dermatitis, which can occur due to friction, moisture, or contact with irritants. If you are using any products that might be causing an allergic reaction or irritation, such as soaps or lotions, it may be worth considering switching to hypoallergenic options. Additionally, if you are experiencing itching, this could indicate a fungal infection, such as candidiasis, which is not uncommon in warm, moist areas of the body.

The use of topical antifungal creams, like the one you mentioned (甘得黴乳膏), can be effective if a fungal infection is present. However, if you have been using it for an extended period without improvement, it may be time to reassess the diagnosis. It's crucial to follow up with your healthcare provider, as they may need to perform a more thorough examination or even take a culture to determine the exact cause of your symptoms.

In terms of your hygiene routine, ensure that you are thoroughly rinsing the area and allowing it to dry completely before applying any creams. Using a blow dryer on a low setting can help, but be cautious not to overheat the skin. When applying any topical medication, use a thin layer and avoid excessive rubbing, which can exacerbate irritation.

Given that you have not engaged in sexual activity for some time, it’s also worth considering whether any changes in your routine or stress levels may be contributing to your symptoms. Stress can sometimes exacerbate skin conditions, so managing anxiety and ensuring you are in a relaxed state may also be beneficial.

In summary, the redness and peeling in the coronary sulcus area could be due to a variety of factors, including hygiene practices, skin irritation, or an infection. It is advisable to return to your healthcare provider for further evaluation, especially since your symptoms have not improved. They may recommend a different treatment approach or further testing to identify the underlying issue. Remember, it’s essential to communicate openly with your doctor about all your symptoms and any changes you notice. Take care, and I hope you find relief soon!
