Small Bumps on the Scrotum: Causes and Concerns - Urology

More Info

---

When it comes to small bumps on the scrotum, there are several potential causes that can be considered. The fact that you describe these bumps as being small, movable, and painless is a good sign, as it often indicates that they are benign. However, it is essential to understand the various possibilities and when to seek medical attention.

One of the most common causes of small bumps on the scrotum is sebaceous cysts. These are non-cancerous lumps that form when sebaceous glands become blocked. They are typically filled with a fatty substance and can vary in size. Sebaceous cysts are usually painless and can be moved under the skin, which aligns with your description. They often do not require treatment unless they become infected or bothersome.

Another possibility is folliculitis, which is the inflammation of hair follicles. This can occur due to irritation, infection, or blockage of the follicles. Folliculitis can present as small red or white bumps and may sometimes be itchy or tender, but it can also be asymptomatic. If the bumps are indeed folliculitis, they may resolve on their own or with topical treatments.

Pearly penile papules are another benign condition that can appear on the scrotum or the shaft of the penis. These are small, dome-shaped bumps that are usually white or skin-colored and are completely harmless. They are a normal anatomical variant and do not require treatment.

In some cases, small bumps can also be a sign of sexually transmitted infections (STIs), such as genital warts caused by the human papillomavirus (HPV). These bumps may appear as small, flesh-colored or gray growths and can be itchy or uncomfortable. If there is any concern about STIs, it is crucial to consult a healthcare provider for appropriate testing and treatment.

While the bumps you describe do not seem to be causing any discomfort or symptoms, it is always wise to monitor any changes. If the bumps grow in size, change in color, become painful, or if you develop any additional symptoms such as discharge or swelling, it would be prudent to seek medical evaluation. A healthcare professional can perform a physical examination and may recommend further tests if necessary to rule out any serious conditions.

In summary, while small, painless bumps on the scrotum are often benign and can be attributed to conditions like sebaceous cysts, folliculitis, or pearly penile papules, it is essential to remain vigilant. Regular self-examinations and awareness of any changes in your body are key to maintaining your health. If you have any concerns or if the bumps change in any way, do not hesitate to consult a healthcare provider for peace of mind and appropriate care.
