Hi doctor,

I have had a rash on the head of my penis for around two months. They are purplish, sore, and tender to touch. I have seen my primary care doctor and he was not sure about the condition and gave me Triamcinolone acetonide cream over two weeks ago. It has not helped. I was also tested recently for STD and all of which came back negative except herpes 1 which I have had for a long time. Any advice would be greatly appreciated. I do not believe this to be any kind of normal discoloration since some spots and sores were present.



Welcome to icliniq.com.

The condition you are suffering is not STD (sexually transmitted disease) for sure because none of the STD is present like this. There are three most common probability of your problem.

  1. Penile Lichen planus: It present in a similar manner with purplish color, itching may or may not be there.
  2. Lichen Sclerosus et Atrophicus: Lichen Sclerosus starts as purplish patch, later on atrophy develop and becomes white in color. It usually associated with intense itching and patient may have dyspareunia.
  3. Allergic contact dermatitis: Due to cloths or condoms.
  4. Are you suffering from any other medical illness or autoimmune disorders or thyroid or hypertension or diabetes?
  5. You have not mentioned the predominant complaint in that purplish lesion. Is it itching or burning or paining? What is it nature?
  6. Are you on any medication? Because, certain medications can cause fixed drug eruption like that.

Hi doctor,

Thank you for the reply.

The only medical condition I have is erectile dysfunction associated with PTSD. I use Viagra a few times a month and have been for several years and never had any side affects except my eyes being sore. I also have no known allergies. The lesion does not itch but it is painful to touch. Should I worry about this being contagious?



Welcome back to icliniq.com.

Fine, it is not a fixed drug eruption. No, it is not STD and so not contagious. I am pretty sure it is an autoimmune disorder. A final diagnosis can only be made on physical examination and histopathological examination. Nevertheless, you can use Clobetasol ointment, twice daily for 15 days. As Clobetasol is a superpotent steroid it should not be used without monitoring that is do not keep on applying always if got relieved. Triamcinolone is a low-potency steroid and will not work in it.
