Why is there a circle of small particles at the base of the glans?

A circle of small particles at the base of the glans may be caused by pearly penile papules, ectopic sebaceous glands, or genital warts. Pearly penile papules usually appear as small white or skin-colored particles that are neatly arranged ； Ectopic sebaceous glands appear as light yellow particles ； Genital warts are often cauliflower-shaped and may grow in size. It is recommended to seek medical treatment promptly for a clear diagnosis.

1. Pearly penile papules

Pearly penile papules are benign lesions that may be related to poor local hygiene or excessive foreskin. The particles are dome-shaped, 1-3 mm in diameter, and are painless and itchy. Usually no treatment is needed, just keep the perineum clean and dry. If it affects the appearance, it can be removed by laser or freezing. Avoid squeezing or using corrosive drugs on your own.

2. Ectopia of sebaceous glands

Ectopia sebaceum is caused by abnormal development of sebaceous glands. The particles are light yellow or white and have a smooth surface. It often occurs on the inside of the foreskin or the coronal sulcus, and may be related to changes in hormone levels. Generally, no special treatment is required, but it needs to be distinguished from infectious diseases. Breathable cotton underwear should be chosen for daily use to reduce local friction and irritation.

3. Genital warts

Condyloma acuminata are caused by human papillomavirus infection. They initially appear as tiny reddish papules that may fuse into cauliflower-like growths in the later stages. It is contagious and needs to be confirmed by acetic acid white test or pathological examination. Drugs such as podophyllotoxin tincture and imiquimod cream are commonly used in clinical treatment, and photodynamic therapy can be used in stubborn cases.

4. Folliculitis

Folliculitis is mostly caused by bacterial infection of hair follicles and manifests as red papules with tenderness that may form pustules. Mupirocin ointment or fusidic acid cream can be applied topically, and in severe cases, cefuroxime axetil tablets can be taken orally. You need to avoid scratching on a daily basis, pay attention to sterilizing instruments when shaving, and keep the affected area clean.

5. Allergic reaction

Contact with allergenic substances such as condoms and detergents may cause allergic dermatitis, with red papules and itching. Immediately discontinue the suspected allergen and use topical hydrocortisone cream to relieve symptoms. Those who have had recurring attacks need to do a patch test to identify the allergen. It is recommended to choose hypoallergenic bath products and avoid topical use of irritating skin care products.

Pay attention to the daily cleaning of the perineum, wash it with warm water every day and dry it thoroughly. Avoid wearing tight synthetic underwear and choose loose and breathable cotton clothing. It is prohibited to use strong disinfectants or home remedies on your own. If the particles continue to enlarge, rupture and bleed, or are accompanied by secretions, you should seek immediate medical attention from a dermatologist or urologist. Regular work and rest and a balanced diet can help maintain immune function and reduce the risk of infection.
