a Persistent Black Spot on the Glans: Causes and Concerns - Urology

More Info

---

A persistent black spot on the glans (the head of the penis) can be concerning, especially when it appears suddenly and remains unchanged over a long period. Given your description, there are several potential causes for this condition, and it is important to consider them in the context of your overall health and medical history.

1. Benign Pigmented Lesions: The most common cause of a black spot on the glans is a benign pigmented lesion, such as a melanocytic nevus (mole) or a lentigo (age spot). These lesions are typically harmless and can be present from childhood. Since you mentioned that the spot has not changed in size, shape, or color over the years, it is likely to be benign.

2. Fordyce Spots: These are small, painless, pale bumps that can appear on the glans and are caused by enlarged sebaceous glands. They are completely normal and do not require treatment.

3. Pearly Penile Papules: These are small, dome-shaped bumps that can appear around the corona of the glans. They are a normal anatomical variant and are not associated with any disease.

4. Post-Inflammatory Hyperpigmentation: If there was any previous irritation or trauma to the area (even if you do not recall it), it could lead to localized hyperpigmentation. This is a common response of the skin to injury.

5. Sexually Transmitted Infections (STIs): While you mentioned having no sexual experience, it is still important to consider that some STIs can cause changes in the skin. However, these typically present with additional symptoms such as pain, itching, or discharge. Since your spot is painless and has remained unchanged, it is less likely to be related to an STI.

6. Skin Conditions: Conditions such as lichen planus or psoriasis can also cause changes in pigmentation, but these usually come with other symptoms such as itching or scaling.

Given that you have had this spot for over a decade without any changes or symptoms, it is likely benign. However, it is always advisable to have any persistent skin changes evaluated by a healthcare professional, especially if there are any changes in appearance, size, or if new symptoms develop.


Recommendations:
- Regular Monitoring: Keep an eye on the spot for any changes in size, shape, color, or if it starts to itch or bleed. If any of these changes occur, seek medical advice.

- Consult a Dermatologist: If you have concerns or if the appearance of the spot changes, consider consulting a dermatologist for a thorough examination. They may perform a dermatoscopic examination or, if necessary, a biopsy to rule out any serious conditions.

- Maintain Good Hygiene: Ensure proper hygiene in the genital area to prevent any potential infections or irritations.

In conclusion, while the persistent black spot on your glans is likely benign, it is always best to consult a healthcare professional for peace of mind and to rule out any potential issues. Regular check-ups and being aware of changes in your body are key components of maintaining good health.
