Subcutaneous Nodules on the Penis: Causes and Treatment

A long, strip-like protrusion under the skin of the penis that resembles cartilage or tendon?

Doctor, I recently discovered a soft, cartilage-like elongated lump under the skin on the right side of the middle of my penis.
It is not very noticeable in appearance but is quite prominent to the touch, with no pain upon pressure, measuring about 2 to 2.5 cm.
What could this condition be? Do I need to seek medical treatment? Additionally, I have recently started taking health supplements such as saw palmetto, ginseng, and angelica in capsule form.
Could this be related? Thank you.

More Info

Subcutaneous nodules on the penis can be concerning for many individuals, and understanding their potential causes and treatment options is essential. Based on your description of a soft, cartilage-like structure measuring approximately 2 to 2.5 cm, it is important to consider several possibilities.

One common cause of subcutaneous nodules in the genital area is Peyronie's disease, which is characterized by the development of fibrous scar tissue inside the penis, leading to curved, painful erections. However, Peyronie's typically presents with a more pronounced curvature and may be associated with pain during erections. Another possibility is sebaceous cysts, which are benign lumps filled with sebum that can occur anywhere on the body, including the genital area. These cysts are usually painless and can vary in size.

Another potential cause could be lipomas, which are benign tumors made of fat tissue. They are generally soft and movable under the skin. Additionally, epidermoid cysts can also appear as nodules and are formed from keratin. These are typically harmless and may not require treatment unless they become infected or bothersome.

Regarding your recent use of dietary supplements such as saw palmetto, ginseng, and angelica, there is limited evidence to suggest that these supplements directly cause subcutaneous nodules. However, individual reactions to supplements can vary, and it is always wise to monitor any new symptoms that arise after starting a new regimen.
In terms of treatment, if the nodule is asymptomatic (not causing pain or discomfort), it may not require immediate intervention. However, it is crucial to have a healthcare professional evaluate the nodule to rule out any serious conditions, such as infections or tumors. A urologist or dermatologist can perform a physical examination and may recommend imaging studies if necessary. If the nodule is found to be benign, treatment may not be needed, but if it is causing discomfort or concern, options such as surgical removal may be considered.

In summary, while subcutaneous nodules on the penis can be benign, it is essential to consult a healthcare provider for an accurate diagnosis and appropriate management. Monitoring any changes in size, shape, or associated symptoms is also important. If you experience any pain, changes in urination, or other concerning symptoms, seek medical attention promptly.
