In fact, this disease is neither a tumor nor a venereal disease. Medical experts after doing pathological section has confirmed that its structure is normal connective tissue proliferation. In medicine, it is named as pearly penile papulosis.

The cause of pearly penile papulosis is not yet clear, and the judgment is mainly based on the location and pattern of the distribution of the rash. There is no specific treatment for this disease and no treatment is required. The most important thing for people suffering from this condition is to recognize the disease and free themselves from fear and worry. This disease does not have any effect on health or the physiological function of the penis.

2) White spots

White spots of different shapes may appear on the glans, some are all white, some are whiter, painless and itchy, the surface is smooth and not accompanied by other rashes, and the pigmentation around them is often deepened compared with the normal skin color. There is no specific treatment for this disease, but it can often be cured without treatment.

Since the white spots on the glans are related to the chronic stimulation of foreskin scale, and the white spots have the possibility of malignant changes, therefore, the white spots on the glans with prepuce or prepuce should be circumcised as early as possible.

3) proliferative erythema

The performance is a single or several erythema at the glans, which can be round, ring or irregular, with a clear boundary, slightly high and hard, and a bright surface. Sometimes there may be erosion, crusting or papillary hyperplasia. The condition may remain unchanged for many years or may become cancerous.

The etiology of proliferative erythema is unknown, but it mainly occurs in circumcised people, so it is thought to be related to circumcision and stimulation of foreskin scale. The author has done circumcision for several patients with this disease, and the erythema of several of them disappeared naturally. Therefore, the foreskin should be routinely removed in all patients with this disease. There is no definite opinion on the treatment of proliferative erythema. Some scholars advocate excision of the foreskin and close observation; some doctors advocate freezing or irradiating the lesions with X-rays.

Also, this disease is also known as erythema proliferatum or red hypertrophy. Patients who find erythema on the glans should not avoid medical treatment, but should go to the urology department of the hospital as soon as possible to see a doctor and make circumcision.

4) skin horns

The performance of the glans grew matchsticks or chopsticks thick and thin horn-like bumps, brown or brownish gray, hard texture. It is thought to be a superfluous organism formed by the proliferation of epidermal keratinocytes on the basis of inflammation of the glans. The dermal horn is thought to be a precancerous lesion.

Dermal horns are well characterized and are not difficult to diagnose. Treatment is local excision. It should be noted that patients suffering from glans skin angle should seek medical treatment as soon as possible, and should never be embarrassed or try to remove it by themselves, so as not to aggravate the condition, or delay the diagnosis and treatment, leading to serious consequences.

5) Angioedema

Like urticaria, it is an acute allergic reaction of the glans to food, drugs or insect bites. It can occur only in the glans or at the same time as urticaria. Children are prone to glans edema, which manifests as a highly edematous and shiny foreskin at the glans, like a large blister. However, it does not affect urination. The disease often occurs at night, the itch is not significant, there is no systemic discomfort, can be a few days after the self-subsidence.

The diagnosis of angioedema of the glans is simple and the treatment is easy, the local should pay attention to keep clean and dry, if necessary, can be used 1:1000 new cleaner wipe lesions. Combined with systemic urticaria can be oral paracetamol, phenylephrine treatment, but under the guidance of the doctor to use drugs.

6) Fixed drug rash

Often due to oral sulfonamides, barbiturates, antipyretic and analgesic drugs, within a day of taking drugs, or even a few minutes of the sudden onset. Manifestation of a round or oval plaque at the glans, the size is not certain, the center of the purplish-red swelling, surrounded by red color, local itching or burning sensation. In severe cases, the center rapidly develops into blisters, which form a wet and rotten surface after bursting, and can only be healed after more than ten days, and there is pigmentation, which can only gradually subside after a few months to a year. Later, every time the patient takes the sensitizing drug, the rash will recur, and the area will be bigger and bigger.

This disease is not difficult to diagnose, with a history of drug use and the above symptoms are easy to confirm the diagnosis, especially with a history of recurrence of the diagnosis is easier. The identification of fixed drug rash on the glans and angioedema is also not difficult, there is a history of drug use, more severe symptoms are fixed drug rash.

Prevention of fixed drug rash is more important than treatment. Patients should keep in mind the drugs they are allergic to, and should take the initiative to explain when they see the doctor, and never use those drugs again.

It should be noted that tuberculosis rash occurs as a result of an allergic reaction of the skin to tuberculosis foci elsewhere, and does not contain Mycobacterium tuberculosis within the lesion itself.

The treatment of tuberculosis rash should be oral anti-tuberculosis drugs, the patient should not be treated privately, but should ask the physician to give guidance on the use of drugs.

9) Condyloma acuminatum

Often develops 3 weeks - 8 months after sexual contact, the lesion is located in the head of the penis, the coronary groove, the prepuce ligament, the urethral orifice, etc., it is a soft, papillomatous flesh bumps, grayish white, yellowish or pinkish red, easy to bleed when touched.

Usually there is no pain and other discomfort, but in sexual intercourse can damage the female vaginal mucosa. Treatment requires surgical local excision.

14) glans phimosis

This is a glans phimosis with the highest incidence. Patients almost always have a prepuce or phimosis. Between the glans and the overgrown foreskin, a warm, moist bacterial culture medium is formed due to shed epithelial cells, glandular secretion, and bacillus circumcision, which can cause inflammation once bacteria enter.

The onset of glans circumcision can be seen in the initial stage of the glans and the surface of the foreskin edema, congestion, redness around the opening of the urethra and the emergence of trauma, vesicles, and can be developed into superficial ulcers, with purulent discharge, the patient consciously at the head of the penis

Repeated episodes of candida glans, can cause foreskin dry cracks, fibrosis and sclerotic changes of the glans.

The treatment of glans circumcision: local available 1:5000 potassium permanganate bath soak the glans, morning and evening once, or with a cotton swab dipped in 1:1000 of the new cleaner gently wipe the ooze or pus, pay attention to do not use a variety of ointments and powders, otherwise easy to aggravate the condition. Heavy systemic reaction can be added with antibiotic treatment. The general treatment effect is not obvious, should pay attention to the diagnosis and treatment of special pathogenic microorganisms. If Candida is detected in the secretion, it should be given local mycobacteria or clotrimazole. If trichomonas is detected in the secretion, mirex should be given orally. If there is a suspicion of venereal disease, gonococcus should be examined in the secretion, and attention should be paid to differentiate from the hard chancre and soft chancre.

I hope this helps
