a Small Bump Near the Penis: Possible Causes and Concerns - Urology

Share to:

There is a small flesh-colored lump next to the base of the penis?


I would like to ask the doctor what this bump could be in terms of a sexually transmitted infection.
It is about 1 centimeter in size, and if you look closely at the center of the bump, there is a small black dot.
It appears pink, has no pus, and is neither painful nor itchy.
I hope to receive an answer!

More Info


When it comes to a small bump near the penis, especially one that is about 1 cm in size, pink in color, and has a black dot in the center, there are several potential causes to consider. It's important to approach this situation with caution and a focus on proper medical evaluation.

1. Pearly Penile Papules: One common benign condition that can present as small, painless bumps on the penis is pearly penile papules. These are normal anatomical variations and are not associated with any disease or infection. They typically appear as small, dome-shaped bumps around the corona of the glans and are often mistaken for other conditions.

2. Folliculitis: Another possibility is folliculitis, which is the inflammation of hair follicles. This can occur due to irritation, infection, or blockage of the follicles. Folliculitis usually presents as small red or white bumps that may be itchy or tender, but in some cases, they can be painless.

3. Sebaceous Cysts: Sebaceous cysts are another benign option. These cysts can form when sebaceous glands become blocked. They are usually painless and can appear as small lumps under the skin. If the cyst becomes infected, it may become red, swollen, and painful.

4. Genital Warts: Caused by the human papillomavirus (HPV), genital warts can appear as small, flesh-colored or pink bumps. They can be flat or raised and may sometimes have a cauliflower-like appearance. While they are typically painless, they can be itchy or uncomfortable.

5. Molluscum Contagiosum: This viral infection can cause small, firm, raised bumps on the skin, often with a central dimple. These bumps can be pink or flesh-colored and are usually painless. Molluscum contagiosum is contagious and can spread through skin-to-skin contact.

6. Other Conditions: Other potential causes could include herpes simplex virus (HSV) lesions, which typically present as painful blisters, or other sexually transmitted infections (STIs). However, given that you mentioned the bump is not painful or itchy, these are less likely.

Given the variety of potential causes, it is crucial to consult a healthcare professional for an accurate diagnosis. A dermatologist or urologist can perform a physical examination and may recommend further testing if necessary. They may also inquire about your sexual history, any recent changes in your health, or other symptoms you may be experiencing.

In the meantime, it is advisable to avoid self-diagnosing or treating the bump without professional guidance. Refrain from picking at or squeezing the bump, as this can lead to infection or scarring. Additionally, practicing safe sex can help prevent the spread of STIs and protect your overall sexual health.

In summary, while there are several benign explanations for a small bump near the penis, it is essential to seek medical advice for a proper diagnosis and treatment plan. Early intervention can help address any concerns and ensure your health and well-being.
