I often meet patients in the clinic or on the Internet who ask whether they have external genital diseases because they have small particles of papules under the edge of the head of the penis, and although they are not painful or itchy, they are afraid. I even suspect that I have an STD. This is the reason why you can’t stop worrying. In fact, this is a normal physiological symptom that is very common among our male doctors in the clinic, called penile pearl-like papules. It is not necessary to be concerned about this phenomenon, and don’t be fooled by unscrupulous hospitals or doctors. The author searched on Baidu with penile pearly pimples and found that many private hospitals advertise this as a disease and lure patients to their homes for the so-called treatment, so I hope you keep your eyes open and don’t be fooled. According to Baidu Encyclopedia: this disease may be a physiological developmental variation, neither a tumor nor a venereal disease. The clinical manifestations are white, skin colored or light red papules that do not fuse with each other and are arranged in one or several rows along the coronal sulcus at the back edge of the glans. It is commonly known as “glans pearly whites”. In medicine, it is named as pearly penile papulosis. Medical experts have confirmed that the structure is normal connective tissue hyperplasia after making pathological sections. The assertion depends mainly on the location and shape of the rash distribution. There is no specific treatment for this disease, and no treatment is needed. Often young men they are worried about the growth of a tumor, and some are afraid that they have a sexually transmitted disease. In the sexual medicine consultation letter, there are not a few who ask about this lesion, and they describe it very specifically: the rash is the size of a small rice grain, similar in color to the surrounding skin, not painful or itchy, and although it does not affect urination or sexual life, the psychological pressure of a few people who do not understand this physiological phenomenon is very high. The disease does not have any effect on health and the physical function of the penis. The most important thing for those who suffer from this disease is to recognize this phenomenon and to free themselves from fear and anxiety. The cause is not yet clear, but according to my observation, it is more likely to arise in those who are locally moist, so it is recommended to wait for the local dryness before putting down the foreskin after bathing or washing the penile area, which helps to reduce the production of penile pearly papules.
