Shaft of penis has white patches

Patient: Hi….I have “white blotches” on the shaft of my penis…pretty much a loss of pigmentation. Just curious what it could be from and is there any way to fix it?

Symptoms: White patches

Doctor: Thanks for your question . It can be due to ringworm or dermatitis skin. You need to get it examined from a dermatologis t to confirm the diagnosis as treatment is diagnosis specific. I guess , little more medical information needed .Hope this helps.
