Small bumps on the penis?


Hello doctor, a few days ago I noticed small bumps the size of a grain of rice on the shaft of my penis below the glans.
They look somewhat like vascular protrusions, but they are colorless and do not resemble the color of veins.
Sometimes these bumps disappear and I can't feel them, while at other times they reappear.
Is this phenomenon normal? Could you please clarify my concerns? Thank you.

Dr. Xu Weikai reply Urology


Alex: Hello, may I ask if it hurts? Is the location on the glans, the coronal sulcus, or on the shaft of the penis? Can it be moved when you push it with your hand? I apologize, but there isn't enough information provided to make a judgment.
If there are any details that are unclear, feel free to ask again, and we can discuss and research further.
This response is from Dr.
Hsu Wei-Kai, Director of the Urology Department, Taitung Hospital, Department of Health, Executive Yuan.

More Info


When it comes to small bumps on the penis, particularly those that appear near the glans (the head of the penis), there are several potential causes that could explain this phenomenon. Based on your description, it sounds like you are experiencing small, sometimes transient bumps that resemble vascular protrusions but lack color. This can be concerning, but it is important to understand that not all bumps or growths in this area are indicative of a serious medical condition.

One common cause of small bumps on the penis is Pearly Penile Papules. These are small, harmless, dome-shaped bumps that typically appear around the corona (the ridge of the glans). They are a normal anatomical variant and are not associated with any disease or infection. Pearly penile papules are usually skin-colored and do not cause any pain or discomfort.

Another possibility is Fordyce Spots, which are small, painless, pale bumps that are actually enlarged sebaceous (oil) glands. They are also completely normal and do not require treatment. Fordyce spots can appear anywhere on the genital area and are often more noticeable when the skin is stretched.

If the bumps you are experiencing are more pronounced, painful, or associated with other symptoms such as itching, discharge, or changes in skin color, it could indicate a different issue. Conditions such as folliculitis (inflammation of hair follicles), genital warts (caused by the human papillomavirus), or even herpes simplex virus infections could present with similar symptoms. These conditions may require medical evaluation and treatment.

The transient nature of the bumps you described—where they sometimes disappear and then reappear—could suggest that they are related to changes in blood flow or pressure in the area, which can occur due to various factors including arousal or physical activity. However, if the bumps are persistent or changing in appearance, it is advisable to seek medical attention.

In summary, while small, painless bumps on the penis can often be benign and normal, it is essential to monitor any changes in size, color, or associated symptoms. If you have concerns about the bumps or if they cause discomfort, it is best to consult a healthcare provider for a thorough examination and appropriate diagnosis. They can provide reassurance, rule out any serious conditions, and discuss potential treatment options if necessary. Remember, maintaining open communication with your healthcare provider about any changes in your body is crucial for your overall health and well-being.

Hello: It could possibly be a cholesteatoma, but if it grows, it may be a sexually transmitted infection such as genital warts. A biopsy is needed for diagnosis. Cholesteatomas do not grow; they only vary in visibility. Wishing you good health.
