annular shaped bumps on penis glans(glands)

On the head of my penis are like three barely visible circular shapes.  Their borders slightly raised, forming a thin ring.  They're small, just about a quarter inch in diamter.  They've been there for atleast a couple years now.  They're not itchy, and they don't change in appearance or size. When the skin is stretched around them, the ring turns white (or really just distinctly lighter.) it's been there so long , and it hasn't spread or anything.

I hope that's enough information to give a good idea of what it might be, and am looking forward to your reply.

Thanks.

Hello,
I cannot confirm anything without examination but it can be granuloma annulare, nummular dermatitis or ringworm. Granuloma annulare consists of reddish bumps arranged in a circle or ring which are itchy. Usually it is asymptomatic but due to cosmetic disfigurement topical or oral steroids may be needed. My sincere advice is to get it evaluated from a dermatologist.
Then it has to be differentiated from other possibilities like ringworm and nummular dermatitis also.
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.
