Introduction
Balanitis refers to inflammation of the foreskin, which may be caused by bacterial or fungal infections, manifesting as redness, swelling, and white discharge on the foreskin. It may be accompanied by pain, a burning sensation, and difficulty urinating. Treatment is recommended under medical guidance with antibiotics such as levofloxacin tablets or erythromycin tablets. Topical medications like miconazole nitrate cream or clotrimazole cream may also be used.
Generally, a small white bump on the foreskin may be caused by conditions such as pearly penile papules, smegma accumulation, ectopic sebaceous glands, balanoposthitis, or genital warts. If any abnormalities occur, it is recommended to seek medical attention promptly. Detailed explanations are as follows:
1. Pearly Penile Papules
Pearly penile papules are benign skin growths; the exact cause is not fully understood but may be related to poor personal hygiene, long foreskin, or other factors. They appear as small white or light red bumps on the foreskin, resembling pinpoints or grains of rice, and typically do not cause pain or itching. Usually, no specific treatment is required. If they affect appearance, laser therapy or cryotherapy may be considered. Additionally, maintaining good personal hygiene and avoiding excessive irritation is advised.
2. Smegma Accumulation
Smegma forms when oily secretions from sebaceous glands mix with urine and accumulate inside the foreskin due to long foreskin, phimosis, or inadequate local cleaning. Over time, this buildup can form small white bumps. Keeping the area clean by regularly washing the inner foreskin with water or mild cleansers can help prevent this. In cases of severe redundant foreskin, circumcision may be considered.
3. Ectopic Sebaceous Glands
Ectopic sebaceous glands refer to a condition involving benign overgrowth of sebaceous glands, commonly occurring on the foreskin of the penis. It presents as small white raised bumps. There is usually no redness, swelling, or pain, but the lesions may persist long-term and potentially affect appearance. Generally, no specific treatment is needed. However, proper local care and good hygiene practices—such as timely underwear changes—are important. If the bumps affect appearance or cause discomfort, laser treatment may be an option.
4. Balanoposthitis (Foreskin Inflammation)
Balanoposthitis refers to inflammation of the foreskin, which may result from bacterial or fungal infections. Symptoms include red patches, swelling, and white discharge on the foreskin, possibly accompanied by pain, burning sensation, and difficulty urinating. Treatment should be guided by a physician and may include oral antibiotics such as levofloxacin tablets or erythromycin tablets, as well as topical antifungal agents like miconazole nitrate cream or clotrimazole cream.
5. Genital Warts
Genital warts are a sexually transmitted infection caused by the human papillomavirus (HPV). They manifest as small white or flesh-colored bumps on the foreskin. These warts may cause itching or a pricking sensation and can easily spread to sexual partners during intercourse. Treatment should follow medical advice and may include topical medications such as imiquimod cream, podophyllotoxin ointment, or recombinant human interferon α2b injection.
To reduce the risk of infection, individuals should maintain good personal hygiene, avoid contact with potentially contaminated bodily fluids or blood, adopt healthy lifestyle habits, and support overall physical health.
