A red bump on the foreskin?


I have developed a dark red bump near the base of my penis that has lasted for almost a week.
Should I be concerned, and is there any medication I can apply to treat it?

Dr. Li Yufen reply Dermatology


If it is a folliculitis similar to acne with a pustule in the center, you can apply an antibiotic ointment.
If it persists for an extended period without improvement, it is advisable to consult a dermatologist for a diagnosis.
Thank you!

More Info


When it comes to a red bump near the base of the penis, there are several potential causes that could be at play. It's important to approach this situation with care, as the genital area is sensitive and can be affected by a variety of conditions. Here are some common causes of a red bump in that area:
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacteria or irritation. It can present as red, swollen bumps that may be itchy or tender. Folliculitis can occur due to friction from clothing, shaving, or sweating.

2. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the penis. They are normal anatomical variations and do not require treatment.

3. Genital Warts: Caused by the human papillomavirus (HPV), these can appear as small, flesh-colored or red bumps. They may be flat or raised and can sometimes itch or cause discomfort.

4. Herpes Simplex Virus (HSV): This viral infection can cause painful blisters or sores in the genital area. If the bump is accompanied by other symptoms such as itching, burning, or flu-like symptoms, it may be worth considering.

5. Cysts: Sebaceous cysts can occur in the genital area and may present as painless lumps. They are usually benign but can become infected.

6. Infections: Other infections, such as fungal infections or sexually transmitted infections (STIs), can also cause bumps or lesions in the genital area.

Given that the bump has been present for about a week and you are concerned about it, it is advisable to seek medical attention. A healthcare provider can perform a physical examination and may recommend tests to determine the exact cause of the bump.
In terms of treatment, it is crucial to avoid self-diagnosing or self-treating without professional guidance. Over-the-counter creams or ointments may not be effective and could potentially worsen the condition if the bump is due to an infection or an STI.
If the bump is determined to be folliculitis, a topical antibiotic or antiseptic may be recommended. For viral infections like herpes, antiviral medications can help manage outbreaks. If it is a cyst or a benign condition, monitoring may be all that is necessary, but in some cases, surgical removal might be considered.

In the meantime, here are some general care tips:
- Keep the area clean and dry: Gently wash the area with mild soap and water, and pat it dry.

- Avoid irritation: Wear loose-fitting underwear and avoid activities that may cause friction or irritation.

- Do not pick or squeeze the bump: This can lead to infection or scarring.

In conclusion, while a red bump near the base of the penis can be concerning, many causes are benign and treatable. However, due to the sensitive nature of the area and the potential for sexually transmitted infections, it is best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
