Hard Lumps on the Penis: Causes and Concerns

Corpus cavernosum

Hello! I have a hard lump on the right side of my corpus cavernosum near the glans.
It can only be felt when fully erect.
Normally, the blood vessels are prominent, and there is no discomfort.
The lump has not suddenly increased in size.
I would like to know what possible condition this could be?

Dr. Xu Weikai reply Urology

Hello, the shape of the hard mass resembles a tubular structure.
It is generally a fibrotic sequela of blood vessels or lymphatic vessels.
If it is not tubular, there could be many possibilities.
Further examination is needed.

More Info

The presence of hard lumps on the penis, particularly near the glans (the head of the penis), can be concerning for many individuals. It's important to approach this issue with a clear understanding of potential causes and when to seek medical advice.

One common cause of hard lumps in this area is the development of a condition known as Peyronie's disease. This condition is characterized by the formation of fibrous scar tissue inside the penis, which can lead to curvature during erections and may cause discomfort. However, in your case, since you mentioned that the lump is hard but does not cause discomfort and has not changed in size, it may not be indicative of Peyronie's disease.

Another possibility is the presence of a penile papule or a sebaceous cyst. Penile papules are small, benign growths that can appear on the shaft or glans of the penis. They are typically harmless and do not require treatment unless they cause discomfort or concern. Sebaceous cysts, on the other hand, are small lumps that can form due to blocked sebaceous glands. These cysts are usually painless and can be left untreated unless they become infected or bothersome.

Additionally, the hard lump could be related to a condition known as a penile fibroma, which is a benign tumor made up of fibrous tissue. These are also generally harmless and may not require any intervention unless they cause pain or other complications.

It is also important to consider the possibility of a sexually transmitted infection (STI) or other infections that could lead to the formation of lumps or lesions on the penis. Conditions such as genital warts, caused by the human papillomavirus (HPV), or molluscum contagiosum, can present as lumps and should be evaluated by a healthcare professional.

Given that you have noted the lump is only noticeable during full erection and does not cause any discomfort, it may not be an urgent issue. However, it is crucial to monitor any changes in size, shape, or associated symptoms such as pain, discharge, or changes in sexual function. If you notice any of these changes, or if you have concerns about the lump, it is advisable to consult a healthcare provider, preferably a urologist. They can perform a physical examination and may recommend imaging studies or other diagnostic tests to determine the exact nature of the lump.

In summary, while there are several potential causes for a hard lump on the penis, many of them are benign. However, due to the sensitive nature of this area and the potential for underlying conditions, it is always best to err on the side of caution and seek professional medical advice for a thorough evaluation. Regular check-ups and open communication with your healthcare provider can help ensure any concerns are addressed promptly and appropriately.
