Dear KingKong99,
Thank you for posting the query.
I have carefully gone through all the details and images links that you have provided. I do not think your lesions are related to a STD or a problem with your immune system. It does not appear to be related to a liver problem either. Based on the available information, I am of the opinion that it might be a Fungal infection or a bruise following trauma or friction.
I would be in a better position to tell whether it could be vasculitis or not, if you can answer these questions:
1) Did the lesion blanch on pressure i.e on putting firm pressure did the lesion lose its redness?
2) Was there any itching on the lesion?
3) Was the lesion bilateral i.e on both thighs?
Do get back to me with these details so that I can help you better.
Hope that this information helps and hope that you will get better soon.

Dear KingKong99,
Thanks for writing back.
The appearance of the lesions on the both sides does not hold much relevance here as I suspect it to be due to either local extravasations (leak) of blood from the blood vessels or transient nonspecific vasculitis leading to increased permeability of the blood vessel wall.
However I would recommend you to get some bleeding parameters tested such as clotting time, bleeding time, PT and APtt, which can give a clue to the cause of the lesions. Painless fading lesions such as these are often seen in bleeding disorders, but they rarely occur at one place. Generalized presentation is much more common.
Amongst the causes that you mentioned in your previous post I would rule out STDs and immune related issues in here. Sometimes underlying liver pathology can affect clotting mechanism producing such lesions.

Hello Bharat,
I think I remember getting a similar painless bruise on a similar spot on the opposite thigh a few weeks after the first one. I could be imagining that though. But this series of reddish marks was only on my inner left thigh http://i.imgur.com/XYATd.jpg.
I dont think they blanched but again they are gone and have not reappeared since they appeared that one time months ago.
Zero itching.
