Red spots on the penis and glans?


Hello, doctor! I accidentally noticed red spots on the shaft and the edge of the glans of my penis while showering.
They are flat and not raised, and they sting when touched.
I don't feel any discomfort elsewhere on my body and have no other unusual symptoms.
I have not engaged in any risky sexual behavior.
What could this be?

Hello: If there is no unsafe sexual behavior, it is mostly a general infection.
Keep the area clean and dry; if it gets wet, make sure to dry it.
Wear loose-fitting underwear.
If symptoms return after improvement, seek medical attention.
Wishing you good health.

More Info


When it comes to red spots on the penis and glans, there are several potential causes that could explain your symptoms. It’s important to remember that while some conditions may be benign, others could require medical attention. Here’s a breakdown of possible causes and considerations:
1. Irritation or Allergic Reaction: One of the most common reasons for red spots on the penis is irritation or an allergic reaction. This could be due to soaps, lotions, or other personal care products that come into contact with the genital area. If you’ve recently changed any products, consider reverting to your previous ones to see if the symptoms improve.

2. Infections: Various infections can lead to red spots or lesions on the penis. For example, fungal infections like candidiasis can cause redness and discomfort. Sexually transmitted infections (STIs) such as herpes or syphilis can also present with red spots or sores, although you mentioned no recent sexual activity. However, it’s still important to consider this possibility if you have had any sexual contact in the past.

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

4. Folliculitis: This is an inflammation of the hair follicles, which can occur anywhere on the body, including the genital area. It may present as red spots or bumps and can be painful or itchy.

5. Dermatitis: Conditions like contact dermatitis or eczema can cause redness and irritation on the skin, including the genital area. This is often accompanied by itching or discomfort.

6. Other Skin Conditions: Conditions such as psoriasis or lichen planus can also affect the genital area, leading to red spots or patches. These conditions may require specific treatments.

Given that you mentioned the spots are flat and cause a stinging sensation when touched, it’s advisable to avoid any further irritation. Here are some steps you can take:
- Avoid Irritants: Refrain from using any new soaps, lotions, or other products that may irritate the area. Stick to mild, unscented products.

- Keep the Area Clean and Dry: Maintain good hygiene, but avoid excessive washing or scrubbing, which can worsen irritation.

- Monitor Symptoms: Keep an eye on the spots. If they change in appearance, increase in number, or if you develop additional symptoms (such as pain, discharge, or fever), seek medical attention.

- Consult a Healthcare Provider: If the red spots persist for more than a few days, worsen, or if you have any concerns, it’s best to consult a healthcare provider. They can perform a physical examination and may recommend tests to determine the underlying cause.

In conclusion, while red spots on the penis can be concerning, many causes are benign and treatable. It’s essential to monitor your symptoms and seek medical advice if necessary to ensure proper diagnosis and treatment.
