Lumps in penis and Peyronies disease

When a man discovers lumps in penis tissue that were not there before is often his first indication there is something wrong with him.
Discovering lumps in the penis under the skin surface is not always a guarantee of having Peyronie’s disease.   But finding penis lumps are a common way a man first learns about Peyronie’s disease  since one or more fibrous masses in the penile shaft is a primary diagnostic finding of this problem.  Other early indicators are penis pain, a bend or distortion of the penis shaft that was previously straight, or it could be loss of erection strength that signals a problem worthy of investigation.

Penis lumps and bumps:  Peyronie’s disease or other problems 


Regardless, if you feel lumps in penis tissue that were never noticed before it is a good reason to have your doctor examine your situation.  Normal healthy penile tissue (corpora cavernosa, veins, arteries, lymph nodes, nerves) of the shaft should feel like a dense homogeneous mass of tissue. There is not much detectable structure within the shaft usually. It is always better to have these things checked by your doctor.
On the other hand, feeling an unusual bump or nodule does not always mean the cause is Peyronie’s disease. Other, less common sources that can create one or more, small or large, lumps in penis tissue are:
  1. Local injury creating internal bleeding (hematoma)
  2. Acute penile fracture causing rupture of internal tissue and bleeding
  3. Penile dorsal vein thrombosis
  4. Diabetes mellitus
  5. Chronic alcoholism
  6. Scleroderma
  7. Tertiary syphilis – a deep tissue mass called a gumma develops late in the progression of this sexually transmitted disease
  8. Gout – calcified nodules called tophi can be present in many parts of the body  – important if you notice lumps in penis tissue worsen during a severe gout episode
  9. Metastasis of cancer to the penis – very rare
In Peyronie’s disease one or more bumps or nodules of foreign tissue might be discovered, and at other times no lumps in penis tissue are ever found. It is important to remember that these lumps in the penis are easy to locate when the penis is flaccid, meaning not erect, so it is best to examine yourself at that time.

Lumps in penis caused by fibrous scar tissue

The urological term for these internal penis bumps related to Peyronie’s disease is “scar” because they are composed of fibrous tissue, similar to the scars we have on the skin surface. But using this term is not ideal since it gives a wrong impression that these penis lumps are located on the skin surface, and this is not true. The Peyronie’s bumps in penis tissue are internal, located below the skin surface, within a layer of tissue known as the tunica albuginea. These lumps or masses are quiet variable. Some PD scars or nodules are obvious and easy to locate. Others are so difficult they are never located except with special diagnostic imaging.
When a scar or internal bump is never found, a diagnosis of Peyronie’s disease can still be made if other signs and symptoms are present.  Other indicators are:
                 1. Age of the individual
                 2. History of recent trauma
                 3. History of recent use of drugs that sometimes cause PD as a side effect
                 4. Penile pain
                 5. Recent penile curvature or distortion
                 6. Reduction or alteration of erection strength
When a Peyronie’s scar cannot be found it is usually because it is so:
1.Deep – that it cannot be reached
2.Small – that it cannot be detected with the fingers
3.Flat – that its edges are tapered and thin, like the edge of a roll of cellophane
4.Soft – it blends into the penile tissue
When a person attempts to first locate the internal lump or scar of fibrous tissue it is good to keep in mind that it is always found on the concave (bottom side of the rainbow) surface of a curved penis. You can correctly assume it is there at the concave part of the bend even if it cannot be felt, otherwise there would be no bend. Something must cause the distortion, so it is strong presumptive evidence of the scar immediately below that is causing the curve.

A fibrous lump located on the topside of the penis (most common location) will cause the penis to bend upward; examining that top surface area should result in finding the lump. When the lump is on the underside it will cause a downward penile curvature.  When the penis lump is on the right lateral side of the penis it will cause a curvature to the right.  And when the lump is on the left lateral side of the penis it will cause a curvature to the left.
In most every case of PD a few lumps in penis tissue are found.  These penis lumps will be of different sizes and shapes, as well as in different areas of the penile shaft.  The combined effect of these multiple lumps in penis tissue will be to create a complex distortion that results in twists, curves, hourglass, and cane handle deformities, as well as indentations.

    I was so worried before going to see a urologist. Peyronie’s disease is rare and appears only after 50. Penis hematoma (wounds) however can happen and its calcification leads to a lump, or the feeling of having something strong piercing through your penis. With time, the calcification resorbs and your erections won’t hurt anymore and you won’t have the lump in the penis. Thank you and stop googling your symptoms.

    Greetings Plyful,

    Not so fast, my friend. You are wrong to say “…everyone with a lump in the penis who found this page via Google. No you do not have Peyronie’s disease. This is just a hematoma…”

    You cannot make a blanket statement like that. Just as not all penis lumps are Peyronie’s disease, not all penis lumps are a hematoma. To make an accurate diagnosis of either condition requires that a detailed history and accurate examination be done to determine the cause of the penile mass. In medical practice diagnosis is an art; it is rare to have anything as simple and absolute as the point you are trying to make. There are always exceptions, alternate possibilities, variables and extenuating circumstances to consider.

    In the article you are responding to the first three items mentioned of nine possibilities that could explain the presence of a lump in the penis (besides Peyronie’s disease) are:
    1. Local injury creating internal bleeding (hematoma)
    2. Acute penile fracture causing rupture of internal tissue and bleeding
    3. Penile dorsal vein thrombosis

    The initial plaque of Peyronie’s disease is usually more elevated and obvious than the scar is Peyronie’s disease, and for this reason is more often described as a lump. But during this time there are other signs and symptoms that typically appear as well (history of trauma or certain drug use, variable pain, altered penis size, altered erectile ability, distortion of the penis, palpable mass etc.) that may or may not be present to make a diagnosis of Peyronie’s disease. Few of these signs and symptoms are present when a hematoma is present.

    Peyronie’s disease is not rare. It occurs in up to one out of 15 men over age 55. That is a lot. It seems to be rare because it is not commonly spoken of. There is great shame and embarrassment admitting to the attendant loss of penis size, ED and distortion that are so common in Peyronie’s disease.

    Peyronie’s disease occurs in boys still in their teens. This past month I have spoken to one boy 18 and the other 16 who have medically diagnosed Peyronie’s disease. This young occurrence is relatively rare compared to the more common onset at age 55-60, but it does happen. What is far more common, and contrary to popular thinking, is the occurrence of PD in men in the 25-35 age group. Some days it seems that half the men who contact me are in this young adult category. As society changes and allows for freer discussion of sexual matters and less inhibition about Peyronie’s disease, I predict that the onset will be considerably lowered and that far more frequent teenage occurrence will become acknowledged.

    I went into the hospital for 2 hip replacements with one straight penis, and came out with another one completely. It curves upward towards the top.I tried hitting it with a rubber mallet with a few towels over it so not to flatten it out, but since this happened I also have like nerve pain as well. My Dr said DO NOT hit it again because I can really due a lot of damage. I think it was from those damn catheters while they did the surgery because I had to be on my stomach for the whole surgery. So my Doc is sending me to a urologist.

  4. Dr. Herazy says:

    Greetings Marky,

    Peyronie’s disease starting after catheterization is a lot more common than you would imagine.

    Peyronie’s disease can start from any type of injury, as happens during abusive catheterization, or being hit with a rubber mallet. Inside the penis is a layer of very delicate tissue, called the tunica albuginea. When it is injured it often causes excess collagen and fibrin to be created during the healing process, resulting in Peyronie’s disease.

    Good luck, sir. TRH
