Hi doctor, I have 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.
Hi. 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. Penile Lichen planus: It present in a similar manner with purplish color, itching may or may not be there. 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. Allergic contact dermatitis: Due to cloths or condoms. Are you on any medication? Because, certain medications can cause fixed drug eruption like that. Revert back with the answers to the above questions to a dermatologist online--->
