Painless Pink Lesion on Penis: What Could It Be?

A painless, non-itchy, and non-discharge lesion has appeared on the penile foreskin?

Hello Doctor: In early November last year, I engaged in a risky sexual encounter.
After waiting for a one-and-a-half-month window period, I went to the hospital to get tested for HIV and syphilis, both of which returned negative results at that time.
However, in mid-December, I noticed a small pink patch on my penis that looked like broken skin.
It is flat, without any swelling or sensation, and there is no discharge; it feels like normal skin.
After observing it for a month, it has not disappeared, but there are also no signs of change.
Could this possibly be a sexually transmitted infection, such as genital warts? Here are the images: https://ppt.cc/fstBbx https://ppt.cc/fAp4ex.
Thank you for your response, and Happy New Year!

More Info

The painless pink lesion you describe on your penis could be caused by several conditions, but given your history and the characteristics of the lesion, it is essential to consider a few possibilities.
Firstly, it is important to note that sexually transmitted infections (STIs) can present with various symptoms, including lesions. However, the fact that your lesion is painless, does not have any discharge, and has not changed in size or appearance over a month may suggest that it is not an active STI like genital warts (caused by the human papillomavirus, HPV) or herpes, which typically present with more acute symptoms.

One possibility is that the lesion could be a benign condition such as a pearly penile papule, which is a normal anatomical variation and is not a disease. These small, painless bumps are often found around the corona of the glans and are completely harmless. Another possibility is a sebaceous cyst, which can appear as a small, painless bump on the skin and is filled with sebum. These cysts are also benign and do not require treatment unless they become infected or bothersome.

Another consideration is a condition known as lichen sclerosus, which can cause white patches or lesions on the genital area. This condition is more common in men and can be associated with itching or discomfort, but it can also present as a painless lesion.
While your previous STI screenings were negative, it is still advisable to follow up with a healthcare provider for a thorough examination. They may recommend a biopsy or other diagnostic tests to rule out any serious conditions, including precancerous changes or other dermatological issues.
In terms of treatment, if the lesion is benign and asymptomatic, it may not require any intervention. However, if it is causing you concern or if there are any changes in its appearance, your healthcare provider may suggest options for removal or treatment.

Regarding your concern about STIs, it is crucial to maintain regular screenings, especially after potential exposure. Even though your initial tests were negative, some infections can take time to become detectable. If you have any new symptoms or concerns, do not hesitate to seek medical advice.

In summary, while the painless pink lesion on your penis could be benign, it is essential to consult a healthcare provider for an accurate diagnosis and peace of mind. Regular check-ups and open communication with your healthcare provider about any changes in your sexual health are vital for maintaining overall well-being.
