There are many small lumps on the edge of the glans, which are not painful or itchy.

If there are small white grains on the edge of the glans penis that are not painful or itchy, it is generally necessary to fully consider that it is related to pearly rash. Pearly rash is a benign lesion, and its main cause is due to repeated stimulation by chemical reactions or repeated inflammatory stimulation. Pearly rash is generally not easy to cause disease. When the patient has such clinical symptoms, it is recommended to go to the hospital immediately for relative examination to confirm the diagnosis. Once it is confirmed to be pearly rash, it is recommended to treat it according to laser generator removal or cryoexcision.

If cauliflower-shaped white particles of exudate appear on the glans penis, the first diagnosis to be considered is genital warts. Genital warts are a sexually transmitted symptom caused by human papillomavirus infection. In China, genital warts may rank second among sexually transmitted symptoms and are a common sexually transmitted symptom in the population. The most effective way to avoid infection with genital warts is to avoid multiple sexual partners as much as possible, and condoms should be worn throughout the entire process of sexual intercourse.

From a treatment perspective, if the warts are caused by milky white cauliflower-shaped tumors, lasers or freezing can be used to remove the tumors. Surgery or electrocautery can also be used to remove or electrocauterize the tumors. However, condyloma acuminatum is a very easy problem. Human papillomavirus infection may ambush in the squamous epithelial germ cell tissue. When the body's resistance is relatively good, clinical symptoms may not appear. However, when the immune system is low, a skin lesion with a cauliflower-shaped tumor core will appear.

A circle of white flesh appears under the glans penis. If it is not painful or itchy, and there is no significant change after long-term observation, it is considered to be penile pearly rash. It is a normal physiological change and there is no need to worry or treat it. Penile pearly rash is related to poor hygiene and prepuce. If the penis cannot fully protrude the glans penis when erect, it is considered to be prepuce and you should see a doctor immediately. If necessary, you should consider surgical treatment. You should also open the prepuce every day, clean the glans penis, and maintain hygiene, which is good for your health.
