Lumps, Bumps and Rashes — What’s that on my penis?

Lumps, Bumps and Rashes — What’s that on my penis?

It’s somewhat normal for penises to have lumps, bumps or spots. But when you see redness, burning or blisters it might be time to get your penis checked out.

In general the best way to differentiate between a harmless bump or something more sinister is by the size, shape and color of the spot.

If you see small jagged bumps around the head of the penis it is most likely pearly penile papules. They are present in about 20 percent of all men and are more common among uncircumcised men – but no need to fret, they are not infectious and don’t require treatment.

Small, pea-sized nodules on the scrotum may appear from time to time. They can be filled with pus-like material and is probably just a cyst. It is not infectious and don’t need to be treated but some men choose to have them removed.

Moist skin-colored bumps could be sign of genital warts, which is caused by the human papillomavirus. The warts can cluster like cauliflower. Genital warts are a very common sexually transmitted disease and require medical treatment, because untreated warts can potentially become cancerous.

A small cluster of tiny blister that are painful could be herpes. Herpes patients have recurring outbreaks of genital ulcers accompanied with severe pain and fever. The disease is highly contagious and has no cure.

A single, round ulcer on the penis or scrotum could a sign of syphilis. The ulcer will likely clear up within a few weeks, but you should still seek treatment. Untreated syphilis can lead to heart disease and impaired mental function.

If you are concerned about any lump, bump or rash on your penis, talk to your doctor to rule out sexually transmitted diseases.
