What does it mean when white spots appear on the foreskin?

The appearance of small white spots on the foreskin may be a physiological condition such as ectopic sebaceous glands or pearly penile papules, or it may be a pathological problem such as fungal infection.

Sebaceous heterotopia is a common physiological phenomenon, which manifests as small white or light yellow papules ranging from pintip to millet size, painless and itchy, and is mainly caused by abnormal development of sebaceous glands or changes in hormone levels. Pearly penile papules appear as small pearly white translucent papules arranged in a ring, which may be related to local irritation or hygiene habits. Fungal infections such as candidal balanitis will cause a white film with itching and require antifungal treatment. Genital warts may appear as small white particles in the early stages and are contagious. In a few cases, it may be related to skin diseases such as lichen planus, and a dermatological biopsy is required for diagnosis.

It is recommended to wash the foreskin with warm water every day and keep it dry, and avoid using harsh lotions. Choose pure cotton breathable underwear to reduce local friction. If the white spots continue to enlarge, rupture, or are accompanied by redness, swelling, and exudation, you should seek immediate medical attention from a urology department or dermatology department. Avoid squeezing or using folk remedies to avoid secondary infection. Pay attention to observe changes daily and record the time of occurrence, morphological evolution and other information for the doctor's reference.
