There is a circle of small particles in the coronal groove

The situation of a circle of small particles in the coronal sulcus is very common in daily life. It will not only cause great harm to the patient's physical health, but also seriously affect their normal life and work. Therefore, it is particularly important to understand the relevant knowledge and find scientific and effective treatment methods. This situation may be a symptom of pearly penile papulosis, fixed drug eruption, skin horn, tuberculous rash and other diseases, and timely medical treatment is required.

1) Pearly Penile Papules

In outpatient clinics, young men often come to see doctors because of a row or several pinpoint-sized bead-like papules on their glans. They are worried, some are worried about tumors, and some are afraid of STDs. In sexual medicine consultation letters, many inquire about this disease, and they describe it very specifically: the rash is the size of a millet grain, similar in color to the surrounding skin, and is not painful or itchy. Although it has no effect on urination or sexual life, it causes great psychological pressure.

In fact, this disease is neither a tumor nor a sexually transmitted disease. Medical experts have confirmed through pathological sections that its structure is normal connective tissue hyperplasia. In medicine, it is named pearly penile papulosis.

The cause of pearly penile papulosis is not yet clear, and the diagnosis mainly depends on the location and shape of the rash. There is no specific treatment for this disease, and it does not require treatment. The most important thing for people with this disease is to understand the disease and get rid of fear and worry. This disease has no effect on health and the physiological function of the penis.

2) Skin horn

The symptoms are horn-like protrusions on the glans that are as thick as a matchstick or chopstick. They are brown or brown-gray in color and hard in texture. It is believed that it is a polyp formed by the proliferation of epidermal keratinocytes on the basis of glans inflammation. Cutaneous horns are considered to be a precancerous lesion.

The characteristics of the horn are prominent and it is not difficult to diagnose. The treatment method is local excision. It should be pointed out that patients with glans horns should seek medical treatment as soon as possible, and never be embarrassed or try to remove them by themselves, so as not to aggravate the condition or delay diagnosis and treatment, leading to serious consequences.

3) Fixed drug rash

It often occurs suddenly within a day or even a few minutes after taking sulfonamides, barbiturates, and antipyretic analgesics. It manifests as a round or oval patch of varying sizes on the glans penis, with purple-red swelling in the center and red surroundings. There may be local itching or burning sensations. In severe cases, the center quickly develops into a blister, which ruptures to form a wet, sore surface that takes more than ten days to heal. Pigmentation is often left behind, and it takes several months to a year to gradually subside. After that, every time the patient takes the allergenic drug, the rash on the affected area will recur, and the area will become larger and larger.

The diagnosis of this disease is not difficult. It is easy to confirm the diagnosis if there is a history of medication and the above symptoms, especially if there is a history of recurrence. It is also easy to distinguish between fixed drug eruption and vascular edema of the glans penis. If there is a history of medication and the symptoms are more severe, it is usually fixed drug eruption.

Prevention of fixed drug rash is more important than treatment. Patients should remember the drugs they are allergic to, tell their doctors when they see them, and never use those drugs again. If the disease occurs, the allergenic drugs should be stopped immediately. For mild cases, antibiotic ointment can be applied externally and diphenhydramine can be taken internally. For severe cases, patients should seek medical attention as soon as possible and ask the doctor for diagnosis and treatment.

4) Tuberculosis rash

It often occurs on the glans penis, showing as small red bumps (papules), which are painless and itchy and progress very slowly. Sometimes it ruptures to form small round ulcers without pus, which can gradually heal with scarring. Sometimes it can be combined with skin tuberculosis rash, showing multiple rashes on the limbs, back, head and neck, which can be easily misdiagnosed as acne, folliculitis or cysts. The rash comes and goes and can be absorbed by itself, but each rash generally takes about 20-30 days to heal.

Tuberculosis rash on the glans penis can be diagnosed based on the characteristics of the rash, the patient's history of tuberculosis or tuberculosis contact, and typical rashes in other parts of the body. It should be pointed out that tuberculosis rash is an allergic reaction of the skin to tuberculosis lesions in other parts of the body, and the lesions themselves do not contain Mycobacterium tuberculosis.

Tuberculosis rash should be treated with oral anti-tuberculosis drugs. Patients should not self-treat and should ask a doctor for guidance on medication.

5) Fungal glansitis

It is caused by a fungus called Candida albicans. It usually occurs in patients who have undergone circumcision. The glans penis is shiny red with small pustules or papules on the surface. You can take clotrimazole or ketoconazole, and apply clotrimazole ointment to the affected area.

6) Villous papilloma

There are millet-like swellings on the edge of the coronal sulcus, which are pink papillary protrusions arranged in rows. The protrusions are particularly obvious and hard when the penis is erect. There is no pain or other discomfort at ordinary times, but it may damage the female's vaginal mucosa during sexual intercourse. Treatment requires surgical local excision.
