Penile issues


I have a small black bump that is slightly raised along the midline of my penis.
It doesn't itch or hurt, and it doesn't seem to be getting larger.
Is this a cyst, or could it be related to a penile midline lesion? Thank you.

Hello: If the surface is rough and it has not been present before, it is safer to seek medical examination.
If it has been there previously without any changes, observation is acceptable.
Wishing you good health.

More Info


When it comes to bumps on the penis, there are several potential causes, and it's important to approach this issue with a clear understanding of what might be happening. The bump you describe as "black" and slightly raised, which is neither itchy nor painful, could be a number of different things.
One common possibility is a sebaceous cyst, which is a non-cancerous bump that can occur anywhere on the body, including the genital area. These cysts are typically filled with a fatty substance and can appear as small, raised bumps. They are usually harmless and do not require treatment unless they become infected or bothersome.

Another possibility is a condition known as pearly penile papules, which are small, benign bumps that can appear around the corona of the penis. These are normal anatomical variations and are not associated with any disease or health risk. They are often mistaken for warts or other lesions, but they are completely harmless.

If the bump is dark in color, it could also be a melanocytic nevus (mole) or a dermatological condition such as a skin tag or a benign pigmented lesion. These are generally not a cause for concern unless there are changes in size, shape, or color, or if they become painful or itchy.

On the other hand, if you have any concerns about the bump, especially if it changes over time or if you experience any other symptoms (such as discharge, pain, or changes in urination), it is advisable to consult a healthcare professional. A urologist or dermatologist can provide a thorough examination and determine if any treatment is necessary.

Regarding your question about whether this bump is related to a "penile midline swelling," it is essential to clarify what you mean by that. If you are referring to a condition like a penile fibroma or any other midline swelling, it would be best to have a medical professional evaluate the area. Sometimes, conditions like Peyronie's disease can cause changes in the shape or texture of the penis, but these are usually accompanied by other symptoms such as pain or curvature during erections.

In summary, while the bump you describe may not be a cause for concern, it is always best to err on the side of caution when it comes to changes in your body. Regular self-examinations and awareness of your body can help you catch any potential issues early. If you have any doubts or if the bump changes in any way, seek medical advice for peace of mind and appropriate management.

Hello, how long has this lesion been present? As you mentioned, it could possibly be acne or sebaceous gland ectopia. It may also be folliculitis of the penis, and in rare cases, it could be condyloma acuminatum. I recommend seeking medical attention for an accurate diagnosis.
