What is the cause of the small bump at the base of the penis?

In clinical practice, when men find a small bump at the base of their penis, they first need to consider the cause of the disease. So, what is the matter with a small bump at the base of the penis?

1. Pearly papules:

It is more common in normal people aged 20-30. The papules are 1-2 mm in diameter, pearly grayish white small bumps, and there are many of them. They can be arranged in two rows and distributed on the edge of the coronal groove. This type of papule does not cause discomfort and does not require treatment. It is manifested as papules with a diameter of about 1-2 mm and smooth surface, arranged in rows at the coronal groove, and exists for a long time, does not increase or enlarge, and has no conscious symptoms. This is a normal situation, not a sexually transmitted disease, and does not require treatment.

2. Tuberculosis of glans penis:

The disease progresses slowly, with small black bumps appearing on the glans penis or in the coronal sulcus, which may rupture and form ulcers.

3. Villous papilloma:

There are millet-like swellings on the edge of the coronal sulcus, which are pink nipple-like protrusions arranged in neat rows. They are particularly obvious and hard when the penis is erect.
