Kaposi's Sarcoma and acute HIV?

[catanus37]

Is it possible to develop kaposi's sarcoma as a symptom of acute HIV? My last possible exposure was less than two months ago and now I see semi-painful bruises on my legs that are redish-purple in color. I heard that the difference between a bruise and KS, though, is that when you press your finger on a bruise the color disappears for a few seconds, but with KS the color stays the same when you press on it. I'm really terrified! I was tested for HIV (rapid test) three weeks ago (a month after possible infection) and came back negative. But soon after I had a swollen lymph node, muscle aches and slight fever. Help!

To my knowledge, KS only occurs in advanced HIV, i.e. in people with overt AIDS.  KS lesions do not blanch when pressed.  Further, a negative rapid test a month after the last possible exposure is strong evidenced against HIV, although not definitive.  Also, HIV doesn't cause a single enlarged lymph node (if that's what the swelling is), and a symptom of "slight fever" (i.e., without a measured temperature over 100 degrees) doesn't count as anything.

Bottom line:  You don't have KS, but otherwiseI haven't a clue what is causing the skin symptoms.  You need to see a health care provider and follow his or her advice.  If your HIV risk was substantial, you might need further testing, but not because of any of the symptoms you describe.

Kaposi's sarcoma is absolutely not a sign of acute HIV infection.  It is usually seen with advanced HIV infection and is considered an AIDS defining illness, therefore, not an acute HIV infection.  When you push on a Kaposi's Sarcoma lesion, it does not blanch (become white).  Also, they are not painful.  Your one month test is encouraging, but get a test at 6 or 12 weeks just to be sure.  You don't have Kaposi's.

that's what i'm saying though....when i press on it the color does NOT fade which makes me believe that it is kaposi's sarcoma.

I also misunderstood the fading business.  But still, you cannot have HIV-related KS.  There are many causes of such skin lesions; KS is a rare cause.  Stop speculating and stop trying to figure it out by online searching.  The only appropriate action is to see a health care provider.

my risk of contracting HIV wasn't that high....but i did get a bikini wax and the woman didnt use gloves and placed her hands on my area while i was bleeding. thats the only way i think i could have gotten it.

Good grief.  Zero risk.  No further discussion.
