What are these white cyst-like lesions on my penis?

Hello,

Welcome to icliniq.com.

Although photo of the lesion is not very clear (attachment removed to protect patient identity), as per your description of problem it is looking like molluscum contagiosum. It gets spread by contact, either sexual or nonsexual. It is painless, small, pearl-like solid and non-itchy lesions (same as yours). If you look closely, there will be a pinpoint depression in every lesion. For treatment, it can be removed by needle or electrocautery for that you have to go to a local dermatologist. It is a very simple procedure and require approximately 20 minutes. Because it is an STD (sexually transmitted disease). We should rule out the history of unprotective sexual contact. Also, check for HIV and hepatitis B. Try to send a close picture of that area for better evaluation.
