What's the matter with the small blisters on the glans?

The appearance of small blisters on the glans may be related to factors such as genital herpes, balanitis, allergic reactions, contact dermatitis, and pearly penile papules. It is recommended to seek medical treatment promptly for a clear diagnosis and carry out targeted treatment under the guidance of a doctor.

1. Genital herpes

Genital herpes is mainly caused by herpes simplex virus type 2 infection and is a sexually transmitted disease. The typical manifestation is clusters of small blisters appearing on the glans, foreskin and other parts, accompanied by burning pain or itching, and superficial ulcers form after the blisters rupture. It can be treated with antiviral drugs such as acyclovir cream, penciclovir cream, and famciclovir tablets. During the onset of the disease, sexual contact should be avoided and the affected area should be kept clean and dry.

2. Balanitis

Balanitis is mostly caused by bacterial or fungal infection and is common in people with excessive foreskin. It manifests as glans erythema, edema, small blisters or pustules, which may be accompanied by white discharge. Topical clotrimazole cream and miconazole nitrate cream can be used to treat fungal infections, or erythromycin ointment and mupirocin ointment can be used to control bacterial infections. Daily care should be taken to open the foreskin and clean it thoroughly.

3. Allergic reaction

Contact with allergenic substances such as condoms and detergents may cause local allergic reactions, manifested as itchy blisters on the glans penis. The suspected allergen needs to be stopped immediately, oral loratadine tablets can be used to relieve symptoms, and topical mometasone furoate cream can be used to reduce inflammation. It is recommended to record allergy history to avoid exposure to similar substances again.

4. Contact dermatitis

Friction from clothing or chemical irritation may cause contact dermatitis, with erythema, small blisters and stinging sensation appearing on the glans penis. Compound dexamethasone acetate cream can be used to relieve symptoms, combined with saline wet compresses. Choose breathable cotton underwear and avoid harsh bath products.

5. Pearly penile papules

Pearly penile papules are benign hyperplasia, which appear as small pearly papules neatly arranged in the coronal groove of the glans penis and do not require special treatment. If it affects the appearance, it can be removed by laser or freezing, but there is a possibility of recurrence. This condition has nothing to do with hygiene habits and is not contagious.

Daily care should be taken to clean the perineum and avoid scratching the affected area. Wear loose, breathable cotton underwear to reduce local friction. Sexual intercourse is prohibited during treatment, and partners need to be checked simultaneously. The diet should be light and spicy foods should be avoided. If the blisters continue to increase in number, ulcerate, or are accompanied by fever and other symptoms, you must seek medical attention immediately to check for serious infection or other skin diseases.
