Penile issues


Hello doctor, I have a white patch on the right side near the base of my penis that itches and gets worse when I scratch it.
What could this be? Is it a type of sexually transmitted infection?

When it comes to concerns about a white itchy spot on the penis, particularly near the base, there are several potential causes that should be considered. While it is understandable to be worried about sexually transmitted infections (STIs), it is essential to approach this issue with a broader perspective, as many conditions can present similar symptoms.

1. Possible Causes: The white itchy spot you are experiencing could be due to several reasons:
- Fungal Infections: Conditions such as candidiasis (yeast infection) can cause itching and white patches. This is more common in warm, moist areas and can occur in men, especially if they have diabetes or are on antibiotics.

- Dermatitis: Contact dermatitis from soaps, lotions, or other irritants can lead to localized itching and irritation. If you've recently changed any personal care products, this could be a factor.

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

- Lichen Sclerosus: This is a chronic skin condition that can cause white patches and itching. It is more common in men and can lead to scarring if not treated.

- Sexually Transmitted Infections (STIs): Conditions such as genital herpes or human papillomavirus (HPV) can cause lesions or spots on the penis. If you have had unprotected sexual contact, this should be considered.

2. Diagnosis: It is crucial to have a healthcare professional evaluate the area. A physical examination can help determine the nature of the spot. In some cases, a swab or biopsy may be necessary to rule out infections or other skin conditions.

3. Self-Care and Treatment: While waiting for a professional evaluation, there are some self-care measures you can take:
- Avoid Scratching: Scratching can worsen the irritation and lead to secondary infections.

- Keep the Area Clean and Dry: Gently wash the area with mild soap and water, and ensure it is thoroughly dried afterward.

- Avoid Irritants: Refrain from using scented soaps, lotions, or other products that may irritate the skin.

- Wear Loose-fitting Underwear: This can help reduce moisture and friction, which may alleviate some discomfort.

4. When to Seek Help: If the itching persists, worsens, or if you notice any additional symptoms such as discharge, pain, or changes in the appearance of the spot, it is essential to seek medical attention promptly. Early diagnosis and treatment can help prevent complications and provide peace of mind.

5. Preventive Measures: To reduce the risk of developing similar issues in the future, consider the following:
- Practice safe sex by using condoms to reduce the risk of STIs.

- Maintain good hygiene, but avoid over-washing, which can strip the skin of natural oils.

- Be mindful of any new products you introduce to your routine, and observe how your skin reacts.

In conclusion, while a white itchy spot on the penis can be concerning, it is essential to approach the situation calmly and seek professional evaluation for an accurate diagnosis. Many conditions are treatable, and understanding the underlying cause is the first step toward effective management.
