Hi XXXXX,
Thanks for writng to us.
From the description i could think of only few possibilities
Post inflammatory hyperpigmentation due to wart itself or due to any inflammatory reaction that could have occured due to use of any chemical or medicine application over affected area
Fixed drug eruption- a drug rash occuring due to intake of a medicine to which patient is allergic or sensitive. It occurs at a fixed site whenever the culprit drug is taken. It is quite commonly seen with sulfa drugs, antibiotics and sometimes pain killers too.
annular lichen planus- purplish ring shaped lesion with clear centre
granuloma annulare- small papules may coalesce to form a ring shaped lesion
porokeratosis.

As you can see there could be multiple probabilities, diagnosis of the same requires proper clinical examination. I have gone through the immage attached. The resolution of pic is quite poor and hence the image is quite hazy.
I would appreciate if you would attach another clear resolution image for proper diagnosis and management.
Hoping to hear from you soon.

Hi XXXXX,
Thanks for attaching a better image.
Yes I understand that the lesion is on penile shaft. Let me assure you that we maintain full privacy and confidentiality of the patient and hence name of the patient ,images attached and even prescribed medicines are not for public view.

Now coming to the diagnosis. It probably looks like a lesion of post inflammatory hyperpigmentation. As such lesions of PIH resolve on its own spontaneously with time. So personally I would advise not to apply anything at all and wait for it to disappear spontaneously as genital area is a sensitive area. However if the need be one can use a mild kojic acid, vitamin c or cortisone based cream to help pigmentation resolve fast.
Hope that helped.
Take care
