If you notice a rash or spot on your penis, your mind may go straight to the worst-case scenario.Penile canceror asexually transmitted infection (STI)may be the first things you think of.
Most of the time, an abnormal spot orbump on your penisis not serious. Still, it is important to see your healthcare provider. Here are some of the causes your healthcare provider may look for.
This article discusses some of the causes of rashes and spots on the penis, including infectious and non-infectious conditions.

Non-Infectious Causes of Spots on the Penis
Non-infectious means you cannot get the condition from someone else or pass it on. These conditions tend to be less serious. Still, you should not ignore your condition just because it is non-infectious.
Any of these conditions can lead to scarring of the penis. There may be redness, skin cracks, and tender, sore areas.
Uncircumcised penises are more prone to scarring. The scarring may make it difficult to retract the foreskin. This is a condition known asphimosis.
Inflamed Hair Follicles
Ahair follicleis the bulb-shaped structure in the skin that hair grows from. Inflamed hair follicles, also calledfolliculitis, look like tiny bumps. The may appear beneath the skin of the scrotum or base of the penis shaft. They can be irritating, but are not usually harmful.
This condition can have a number of causes, including:
Pearly Penile Papules
Dome-shaped or jagged bumps that appear around the head, or glans, of the penis may beangiofibromas. These are also known aspearly penile papules.
These bumps are more common on uncircumcised penises. They are not infectious and they do not require treatment. If they are large, they can be removed for cosmetic reasons.
Angiokeratomas
Angiokeratomasare small red or blue spots. They may appear only on the glans or extend to the scrotum, groin, and thighs.The spots are not infectious and do not need to be treated.
Sometimes these spots can cause pain or bleeding. When this happens, they can be treated with laser therapy.Electrodesiccation, a procedure that involves scraping or burning the spots, may also be used.
Psoriasis
Psoriasisis a non-infectious skin disorder. It can appear anywhere on the body. On the penis, it may appear as a red or salmon-colored patch with white or silvery scales.
Psoriasis is anautoimmune disorder. When you have psoriasis, your immune system attacks skin cells on different parts of your body.
Psoriasis can often be treated with topicalcorticosteroids. These medicines are applied on the skin and prevent your immune system from attacking your skin. Oral medications may also help.
An Overview of Genital Psoriasis
Lichen Sclerosus
Lichen sclerosusis a common skin condition. About one in 300 males will develop this condition at some point in their lives.
The lesions are often itchy. They may also lead to painful erections orpainful or difficult urinationdue to the narrowing of the urine channel in the penis.
These lesions can often be treated with topical corticosteroids. Large lesions or those that do not respond to treatment may need to be removed surgically.
Lichen sclerosus is linked to a 4% to 5% percent risk of cancer. Lesions that do not go away should be monitored.
Lichen Planus
The lesions often appear in a ring or a line. They may or may not be itchy.
Lichen planus can affect other parts of the body, including:
The condition is not infectious. The lesions can usually be treated with topical corticosteroids.
It is not known why, but lichen planus affects people withhepatitis Cfive times more often than people without it.
Eczema
Eczemais a chronic skin condition. People with eczema have itchy, red, dry, and cracked skin. Eczema flare-ups can happen anywhere on the body.
Lifestyle changes can help you avoid eczema outbreaks. Wear loose-fitting clothing and avoid harsh chemicals.
Recap
Infectious Causes of Spots on the Penis
Infectious conditions are conditions that can be passed on to others. Infectious conditions of the penis are usually sexually transmitted. These diseases may require medical help.
Human Papillomavirus (HPV)
Human papillomavirus (HPV)is a highly contagious sexually transmitted infection (STI). It is also known as genital warts.
HPV is passed through vaginal sex, anal sex, and oral sex. It can also be passed through skin-to-skin sexual contact, such as mutual masturbation.
In males, HPV warts can develop in the following places:On the penisAround the anusIn the throatInside the rectum
In males, HPV warts can develop in the following places:
In most cases, an HPV infection will resolve on its own. In a small subset of people, the wart may develop into cancer. Some strains of HPV are more likely to cause cancer than others.
Topical solutions can work to gradually remove the wart. A healthcare provider can also cut away, freeze, or burn the wart.
Gay or bisexual men with HPV are at an increased risk of cancer. People in this group who have genital warts or have had them in the past should consider ananal Pap smearto test for cancer.
Signs and Symptoms of Genital Warts
Primary Syphilis
The sore is typically a circular lesion that does not cause pain. It is usually ulcerative, which means there is a loss of surface tissue.
You may be able to see the sore on the penis or around the anus. Unseen sores may also develop in the rectum, mouth, or throat.
The sore is the first symptom of primary, or first-stage syphilis. If left untreated, it can progress to more serious forms called secondary and tertiary syphilis. This may take months or years.
Syphilis may be diagnosed with a blood test. A biopsy, a procedure that takes a small sample of the lesion, can also be used to diagnose the disease.
Syphilis can be treated with a single dose of benzathine penicillin, an antibiotic. The medication is injected into a muscle, usually the buttocks.
If syphilis spreads it can cause long-term damage to the body. In later stages it may even affect the nervous system. If you are diagnosed with syphilis, it is important to get treatment right away.
Genital Herpes
The infection triggers the development of small blisters. These blisters break open into painful sores.The first herpes episode often causes severe pain and flu-like symptoms. Later episodes tend to be milder.
Herpes cannot be cured. Antiviral medications may reduce the risk of recurrence. They may also make active outbreaks less severe.
Certain external factors like stress can also increase the risk of recurrence. If you have active herpes sores, it is important to avoid sex until the blisters are completely healed.
RecapMost infectious causes of spots on the penis are sexually transmitted. These conditions usually require treatment. See your healthcare provider right away to avoid long-term problems and prevent spreading them to someone else.

Molluscum Contagiosum
Molluscum contagiosumis a common viral disease. It can appear anywhere on the body, including the penis. It is easily passed through sexual contact or other types of direct skin-to-skin contact.
Transmission may also happen when you share towels, clothess, gym mats, and personal care items. People with weakened immune systems, such as those with advanced HIV, are especially prone to infection.
Molluscum contagiosum appears as firm, dome-shaped bumps with a dimple in the middle. They are usually flesh-colored. They can appear on the genitals and inner thighs but are also common on the face, neck, armpits, arms, hands, and abdomen.
The bumps are usually painless. They may itch and turn a bright red color when scratched.
The infection usually goes away on its own, but it may take a long time. The bumps usually disappear in six to 12 months, but may last as long as four years.
Some people choose to have the bumps removed for cosmetic reasons. Removing them also reduces the risk of transmission. Topical creams containing retinoids can sometimes help.
Penile Cancer
Penile cancer is a much less common cause of lesions on the penis. Penile cancer affects only around 2,200 Americans a year.
The early or precancerous stage is called penile carcinoma in situ. In this stage the lesion is often red and raised with a velvety texture.
Almost 95% of all penile cancers aresquamous cell carcinomas.These tumors grow slowly. They usually appear as flat skin lesions on the glans or foreskin.
Verrucous carcinoma is a less common type of squamous cell carcinoma. It is also slow growing and can look like a large wart.
Penilemelanomais the most dangerous type. It develops rapidly. Lesions are purplish, brown, or black.
With early treatment most penile cancers can be cured. Delaying treatment can be dangerous. As the cancer grows, more aggressive treatment may be needed. This may include thepartial or complete removal of the penis.
Summary
There are many possible causes of a rash or growth on the penis. Non-infectious conditions are usually less serious. These conditions can often be treated surgically or with topical corticosteroids.
In rare cases, a lesion on the penis may be cancerous. When treated early, most penile cancers can be cured. This is why it is important to see a healthcare provider for any unusual spot, bump, or rash on the penis.
A Word From Verywell
These are only a few of the possible causes of a rash or growth on the penis. That is why self-diagnosis is never a good idea. Early medical care can prevent serious problems. It will also reduce the risk of transmitting infections to others.
If the thought of discussing your penis with your healthcare provider makes you uneasy, it can be helpful to call first. Do not wait to seek treatment. Embarrassment should never come between you and a diagnosis.
