White Bump Under Penis: What Could It Be? - Urology

More Info

---

When it comes to a white bump under the penis, particularly in the area of the foreskin, there are several potential explanations. Given that you describe the bump as being similar to a pimple, measuring about 1.5mm, and that it has been present for some time without causing pain or itching, it is likely to be benign. Here are some common possibilities:
1. Pearly Penile Papules: These are small, white, harmless bumps that can appear around the corona of the glans (the head of the penis). They are a normal anatomical variant and are not associated with any disease or infection. They typically do not require treatment unless they cause cosmetic concerns.

2. Sebaceous Cysts: These are small, non-painful lumps that can occur when sebaceous glands become blocked. They are filled with a fatty substance and can appear anywhere on the body, including the genital area. They are generally harmless and do not require treatment unless they become infected or bothersome.

3. Folliculitis: This condition occurs when hair follicles become inflamed, often due to infection or irritation. While it can cause red bumps, sometimes they can appear white if pus is present. If there are no other symptoms like pain or itching, it may not be a significant concern.

4. Fordyce Spots: These are small, painless, pale bumps that are actually enlarged sebaceous glands. They are common and harmless, often appearing on the shaft of the penis or the scrotum.

5. Genital Warts: Caused by the human papillomavirus (HPV), these can appear as small, flesh-colored or white bumps. They may be painless but can sometimes itch or cause discomfort. If you notice any changes in the bump or if it starts to cause discomfort, it would be wise to consult a healthcare provider.

6. Other Conditions: There are other less common conditions that could cause white bumps, such as molluscum contagiosum (a viral infection that causes small, painless bumps) or even certain sexually transmitted infections (STIs). However, these typically present with additional symptoms.

Given that the bump has been present for a while without any associated symptoms, it is likely benign. However, it is always a good idea to consult a healthcare professional for an accurate diagnosis, especially if there are any changes in size, color, or if you develop new symptoms. A healthcare provider can perform a physical examination and may recommend further tests if necessary.

In summary, while the presence of a small white bump under the penis is often not a cause for concern, it is essential to monitor any changes and seek medical advice if you have doubts or if the bump starts to cause discomfort. Regular check-ups and open communication with your healthcare provider can help ensure your sexual health remains a priority.
