Getting now to the end, we have
HHV8, or human herpesvirus 8,
which has been named Kaposi's sarcoma-
Again, you'll mostly hear people
say Kaposi's virus.
This transmission is via mucosal
secretions, so saliva,
but especially sexual contact.
And the patients who develop diseases
with this particular virus
are those who are immunosuppressed,
either via HIV infection,
which is extended to AIDS, or those
who are transplant recipients, primarily
solid organ transplant patients,
because they have a specific very
of medication which puts them at risk.
Patients with a Kaposi's sarcoma
will demonstrate lesions such as you
see on the images in front of you.
. The sarcoma itself is very dark and
purplish, violet, to use the proper
term, and they're plaque-like
And you can actually see, especially in
the image on the right, sort of,
plaque-like skin on top of a purplish,
very circumscribed lesion
that actually -- both of those represent
So, we're having a reactivation
to the virus itself,
causing -- as a proliferative faction
causing the sarcoma.
So, think of a sort of vascular or a
plaque with scale on top of it, and that
will be your Kaposi's sarcoma.
So, that's a longer presentation because the
herpesviruses include some very
many which we will see quite
commonly in medicine.
But if you can, sort of, keep
in mind the order, so
the herpesviruses 1 and 2
are herpes simplex virus.
3 is going to be varicella-zoster virus,
4 is going to be Epstein-Barr virus,
5 will be cytomegalovirus.
6 and 7 are the roseola viruses,
and 8 is the Kaposi's sarcoma virus.
Put all those together and you got
a whole bunch of badness,
which unfortunately, we'll all probably
see quite frequently.
