What is a small hard bump below the head of my penis?

There are many conditions that can cause penile bumps, and the best way to figure out what is causing the bump on your penis is to go see your doctor. Infectious causes of small firm bumps include genital warts (the HPV virus) and a condition called molluscum contagiosum. Lesions caused by molluscum are often dome shaped and smooth, sometimes with a small dimple in the middle. A physician can help make the diagnosis of these conditions and can also recommend a procedure to remove these lesions. Syphillus in rare cases can cause bumps as well. If you are sexually active it is important to get checked for any sexually transmitted infections. Some people have benign causes of penile bumps included pearly penile papules, penile sebaceous glands (Fordyce spots), or follicular cysts. Scabies can cause a more crusted bump that is often very itchy. Psoriasis can affect the penis and cause a reddish raised bump, and an inflammatory condition called lichen planus can sometimes present with bumps as well. More rarely, but importantly, there can be skin cancers of the penis, which are more common in uncircumcised men. Because there are so many possible causes, some of which are totally benign and others of which can be much more serious, it is best to schedule an appointment to see your doctor. It can be difficult to raise this issue with a physician, but these kinds of questions are very common and doctors are used to addressing these concerns. Please speak with a physician.
