Is it normal for a ring of millet grains to grow in the coronary sulcus?

The appearance of a ring of millet-like protrusions in the coronal sulcus is mostly a physiological phenomenon, and common causes include pearl rash, ectopic sebaceous glands, or mild inflammatory reaction. The main influencing factors are local hygiene conditions, fluctuations in hormone levels, friction irritation, excessive foreskin and pathogenic infection.

1. Pearl rash:

Penile pearly papules are common benign hyperplasia on the edge of the male coronary sulcus. They appear as white or light red dome papules with a diameter of 1-3 mm, arranged in a ring. This phenomenon is related to the local moist environment caused by the excessive foreskin. It is a normal anatomical variation and does not require special treatment. Keeping your skin dry and clean can reduce the appearance of pimples.

2. Ectopic sebaceous glands:

Ectopia sebaceum causes sebaceous glands to form small yellow particles in atypical areas, which are painless to touch. This condition is related to the increase in androgen levels after puberty and occurs at the junction of the inner plate of the foreskin and the coronal sulcus. The particles will not fuse and enlarge, and will not affect physiological functions. Do not squeeze by yourself.

3. Hygiene factors:

Insufficient cleansing may cause smegma accumulation and irritation, causing temporary keratin hyperplasia. It is recommended to wash the foreskin every day and avoid using alkaline lotions. For those with foreskin, it is necessary to wipe away the residual urine after urination to prevent the moist environment from breeding opportunistic pathogens.

4. Contact dermatitis:

Allergy to condom material or detergent residue may cause local allergic papules, often accompanied by itching. Most of the symptoms can be relieved after changing to hypoallergenic products. In severe cases, short-term topical weak corticosteroid ointment is required.

3. Infectious factors:

Human papillomavirus (HPV) infection may initially appear as clusters of small warts, but they are usually rough in texture and grow rapidly. Candida infection is often accompanied by white curd-like discharge and burning sensation. Seek medical attention promptly when progressive enlargement, ulceration or discharge occurs.

It is recommended to wear breathable cotton underwear to avoid prolonged sitting and local high temperature environments. Pay attention to reducing the intake of spicy and irritating foods, and appropriately supplement vitamin B to enhance skin resistance. When there is a clear pathogenic infection, a partner should be treated together, and sexual intercourse should be avoided during treatment. People with recurrent foreskin infections may consider circumcision. If there is no improvement or symptoms worsen after 2-3 weeks of observation, a clear diagnosis needs to be made through acetic acid white test, secretion testing, etc.
