May I ask the doctor?


Hello doctor, I recently noticed two small red spots on the glans of my penis, near the urethral opening, while taking a shower.
I would like to know if this is normal or if it indicates some symptoms.
Thank you for your response.
Sincerely, someone feeling anxious.

When it comes to red spots on the glans (the head of the penis), it is essential to approach the situation with caution and awareness of potential underlying conditions. The appearance of red spots can be attributed to various causes, some of which may be benign, while others could indicate a more serious issue that requires medical attention.

Firstly, it is important to consider the characteristics of the red spots. Are they raised or flat? Are they itchy, painful, or associated with any discharge? These details can help in determining the cause. Common benign causes of red spots on the glans include:
1. Irritation or Friction: Sometimes, red spots can result from irritation due to friction during sexual activity or from tight clothing. This type of irritation is usually temporary and resolves on its own.

2. Allergic Reactions: Contact dermatitis from soaps, lotions, or latex condoms can lead to localized redness and irritation. If you have recently changed any products, this could be a possible cause.

3. Pearly Penile Papules: These are small, harmless bumps that can appear around the glans and are often mistaken for lesions. They are normal anatomical variations and do not require treatment.

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

However, there are also more serious conditions that could manifest as red spots on the glans, and these warrant medical evaluation:
1. Infections: Conditions such as balanitis (inflammation of the glans), sexually transmitted infections (STIs) like herpes or syphilis, and fungal infections can present with red spots or lesions. If there are accompanying symptoms such as pain, itching, or discharge, it is crucial to seek medical advice.

2. Lichen Planus: This is a chronic inflammatory condition that can affect the skin and mucous membranes, including the genital area. It can cause red or purple spots and may be associated with itching or discomfort.

3. Psoriasis: This autoimmune condition can also affect the genital area, leading to red, scaly patches. If you have a history of psoriasis, this could be a possibility.

4. Cancer: Although rare, penile cancer can present as red spots or lesions on the glans. If the spots persist, change in appearance, or are associated with other concerning symptoms, it is essential to consult a healthcare professional.

Given the variety of potential causes, it is advisable to seek medical attention if the red spots persist, worsen, or are accompanied by other symptoms such as pain, itching, or discharge. A healthcare provider can perform a thorough examination, take a detailed medical history, and may recommend tests or treatments based on the findings.

In summary, while some causes of red spots on the glans may be benign, it is always better to err on the side of caution. If you are experiencing anxiety or concern about your symptoms, do not hesitate to reach out to a healthcare professional for guidance and reassurance. Early intervention can lead to better outcomes and peace of mind.
