I would like to help, but really cannot. No online opinion from verbal description can compete with direct examination by two docs, including a dermatologist. The only thing I will say is that your description of the initial lesion makes me wonder about molluscum contagiosum, a trivial viral infection that can be acquried sexually. But a dermatologist would recognize it. As to whether or not you have warts, prominent sebaceous glands, or something else, I simply cannot speculate. I suggest you rely on the dermatologist. If he is uncertain about the diagnosis after a first examination, most likely things will become clear on follow-up.
Good luck-- HHH, MD
If you post a question like this could you also post a picture or something to go along with it so the doctor can actually see it? Is that allowed?
Not on this forum. To my thinking, looking at photos and giving advice comes too close to practicing medicine from a distance, which I will not due and is not the goal of this forum. However, this is permissible on some MedHelp forums, such as dermatology. Each moderator makes his or her own decision, but most don't do it.
