Is it a disease to have small, painless, itchy bumps on the foreskin?

The appearance of small, painless and itchy pimples on the foreskin may be a physiological manifestation, or may be related to diseases such as pearly penile papules and ectopic sebaceous glands. Specific reasons include poor local hygiene, blocked sebaceous glands, viral infection, allergic reactions, chronic inflammatory stimulation, etc.

1. Physiological manifestations

Tiny granular papules may appear on the inner side of the foreskin or the coronal sulcus. They may be skin-colored or white in color and have no subjective symptoms. They may be related to strong secretion of local sebaceous glands or slight accumulation of keratin. This kind of situation does not require special treatment, just pay attention to daily cleaning and avoid using harsh detergents or excessive friction.

2. Pearly penile papules

It is more common on the edge of the coronal sulcus and appears as 1-2 mm pearly white papules arranged in rows, which are benign hyperplasia. It may be related to local friction or changes in hormone levels and usually requires no treatment. If it affects the appearance, laser or cryotherapy can be considered, but it needs to be evaluated by a doctor before operation.

3. Ectopia of sebaceous glands

Sebaceous heterotopia manifests as small, light yellow or white flat pimples, which are painless and itchy, and usually occur on the inside of the foreskin or glans. It is related to abnormal development of sebaceous glands and generally does not require intervention. If there is redness and swelling due to infection, you can use erythromycin ointment or mupirocin ointment to fight the infection as directed by your doctor.

4. Viral infection

Human papillomavirus (HPV) infection may cause early manifestations of flat warts or genital warts, which may be painless and itchy initially, but will gradually increase in size. It needs to be confirmed by acetic acid white test or pathological examination. You can use imiquimod cream or interferon gel as directed by your doctor. If necessary, use laser to remove it.

5. Allergy or chronic inflammation

Contact allergy or long-term chronic inflammatory stimulation may lead to local tissue proliferation and the formation of small pimples. Common triggers include detergent residue, allergies to condom materials, etc. It is necessary to check for allergens and avoid contact. When symptoms are obvious, hydrocortisone cream can be used for short-term relief. Co-infections need to be treated with antibiotics.

It is recommended to wash the foreskin and glans with warm water every day, keep the area dry and clean, and avoid wearing tight underwear. If the pimple enlarges, ruptures, bleeds, or is accompanied by secretions within a short period of time, you should promptly seek medical attention from a dermatology or urology department to rule out the possibility of malignant lesions. Avoid squeezing or using folk remedies on a daily basis to avoid secondary infection.
