Protrusions on the genitalia?

Hello Doctor, recently I have been experiencing dryness of the penis, which has led to peeling.
During the Lunar New Year, I noticed a small bump on my penis, approximately 1 mm in diameter and height, resembling a pimple.
The skin in that area is thin, and if I scratch it with my nail, it comes off and bleeds, but it reappears afterward.
Out of curiosity, I used a magnifying glass along with my phone's flashlight and could clearly see that the bump is a small papule.
Under the light, I noticed red, vessel-like structures within the skin layer.
The surface of the bump appears smooth, and I have been concerned about possibly contracting genital warts from public restrooms.
However, when I visited the hospital, the doctor examined it and suggested that I try to scrape it off and apply an antibiotic ointment, without using the acetic acid test for further evaluation.
This left me confused, as I would like to address it early if it is indeed a concern.
I also tried to leave it alone for a month, and it hasn't shown any signs of growing.
I would appreciate your help in clarifying this situation.
Thank you.

More Info

Understanding small bumps on the penis can be concerning, especially when they appear suddenly or change in appearance. Based on your description, it sounds like you are dealing with a small bump that resembles a pimple or a papule, which has been persistent and has caused some bleeding when scratched.
There are several potential causes for small bumps on the penis, and understanding these can help in determining the appropriate treatment.
1. Pearly Penile Papules: These are small, harmless bumps that are often found around the corona of the glans (the head of the penis). They are normal anatomical variations and do not require treatment unless they cause discomfort or concern.

2. Folliculitis: This is an inflammation of the hair follicles, which can occur due to irritation, infection, or blockage. It can present as small red bumps that may resemble pimples. Treatment typically involves good hygiene and sometimes topical antibiotics if an infection is suspected.

3. Sebaceous Cysts: These are small, non-cancerous lumps that can occur when sebaceous glands become blocked. They are usually painless and can be left alone unless they become infected or bothersome.

4. Genital Warts (Condylomata Acuminata): Caused by the human papillomavirus (HPV), these can appear as small, flesh-colored or gray bumps. They often have a cauliflower-like appearance. If there is concern about warts, it is essential to consult a healthcare provider for appropriate testing and treatment options.

5. Herpes Simplex Virus (HSV): This can cause small, painful blisters or sores on the genital area. If you have a history of genital herpes or experience symptoms like itching, burning, or flu-like symptoms, it is crucial to seek medical advice.

6. Other Skin Conditions: Conditions such as eczema, psoriasis, or contact dermatitis can also cause bumps or lesions on the penis. These may require specific treatments based on the underlying cause.

In your case, since the bump is small, has a smooth surface, and has not changed in size over the past month, it may not be a cause for immediate concern. However, the fact that it bleeds when scratched suggests that it is sensitive and may require attention.
The recommendation from your doctor to apply an antibiotic ointment is a good step to prevent any potential infection, especially if the area has been traumatized by scratching. It is essential to avoid picking at the bump, as this can lead to further irritation or infection.
If the bump does not resolve with conservative treatment, or if you notice any changes in its appearance, size, or if you develop additional symptoms (such as pain, itching, or discharge), it would be wise to follow up with a healthcare provider. They may consider further evaluation, including a biopsy or other diagnostic tests, to rule out any serious conditions.

In summary, while small bumps on the penis can often be benign, it is crucial to monitor their behavior and seek medical advice if there are any concerns. Maintaining good hygiene, avoiding irritation, and following your doctor's recommendations will be key in managing this issue.
