Bumps Under the Penis: Causes and Treatments - Urology

More Info

---

When it comes to bumps under the penis, there are several potential causes, and understanding these can help guide appropriate treatment. It's important to note that while some bumps may be harmless, others could indicate a more serious condition that requires medical attention.


Common Causes of Bumps Under the Penis
1. Pearly Penile Papules: These are small, harmless bumps that often appear around the corona of the glans (the head of the penis). They are a normal anatomical variant and do not require treatment.

2. Fordyce Spots: These are small, painless, pale bumps that are sebaceous glands without hair follicles. They are completely benign and do not require treatment.

3. Folliculitis: This condition occurs when hair follicles become inflamed, often due to infection or irritation. It can lead to red, painful bumps that may resemble pimples.

4. Genital Warts: Caused by the human papillomavirus (HPV), these warts can appear as small, flesh-colored or gray bumps. They can be contagious and may require treatment.

5. Herpes Simplex Virus: This viral infection can cause painful blisters or sores on the genital area. If you suspect herpes, it is important to seek medical advice for appropriate antiviral treatment.

6. Cysts: Sebaceous cysts can occur anywhere on the body, including the genital area. They are usually painless and may require surgical removal if they become bothersome.

7. Lichen Planus: This inflammatory condition can cause flat-topped bumps that may be itchy or painful. Treatment typically involves topical corticosteroids.

8. Penile Cancer: Though rare, any new growth or persistent bump should be evaluated by a healthcare professional to rule out malignancy.


Treatment Options
The treatment for bumps under the penis largely depends on the underlying cause:
- Observation: If the bumps are benign (like pearly penile papules or Fordyce spots), no treatment is necessary.


- Topical Treatments: For conditions like folliculitis or lichen planus, topical antibiotics or corticosteroids may be prescribed.

- Cryotherapy or Laser Treatment: For genital warts, these methods can effectively remove warts.

- Antiviral Medications: If herpes is diagnosed, antiviral medications can help manage outbreaks.

- Surgical Removal: Cysts or other growths that are bothersome may need to be surgically removed.


Over-the-Counter Options
Regarding your mention of "甘得黴" (likely referring to an antifungal cream), it is important to note that antifungal treatments are typically effective for fungal infections, such as jock itch, but they may not be suitable for other types of bumps. If you suspect a fungal infection, it may be worth trying, but if the bump persists or worsens, you should seek medical advice.


When to See a Doctor
You should consult a healthcare professional if:
- The bump changes in size, shape, or color.

- You experience pain, itching, or discomfort.

- There are additional symptoms such as discharge, bleeding, or fever.

- You are unsure of the nature of the bump.

In conclusion, while some bumps under the penis can be harmless, others may require medical evaluation and treatment. It is always best to err on the side of caution and consult a healthcare provider for a proper diagnosis and treatment plan tailored to your specific situation.
