Hello,
Pityriasis versicolor can affect the groins but it is very less likely to affect the penis and cause such hypopigmented spots. I suggest you to get it checked from a dermatologist to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Doctor,
Thank you for your advice. Visually it doesnt look like what I've seen of vitiligo or lichen sclerosus, but obviously your experience is more than mine. Its a difficult situation, I know that doctors have seen it all - but obviously on the penis, there is an embarrassment factor that is making me hesitant to go. I know that you are obviously unable to make a diagnosis thru the web, but did you look at my photo in its large version. Its a pretty close-up high resolution shot. I'm just curious if the visual of the photo makes you lean more towards any certain suspicion of what it could be.
I'm surprised that you say tinea versicolor is uncommon on the penis, given that its a hot humid area.
Warm Regards
Hello,
Pityriasis versicolor is commonly found on the sun tanned areas on the upper trunk but it is rarely found on the penis. From the symptoms lichen sclerosus and vitiligo need to be ruled out although symptoms of lichen sclerosis at this age are less likely.
Vitiligo is a pigmentation disorder in which melanocytes (the cells that make pigment) in the skin are destroyed. As a result, white patches appear on the skin in different parts of the body. Diagnosis can be confirmed by external examination, blood tests to check skin cell count for melanocytes and biopsy of the skin patches.

Any help from a dermatologist?
I've also tried treating it with an OTC Antibiotic cream as well as Tea tree oil.
