Let’s talk about lupus erythematosus,
or systemic lupus erythematosus.
Now, this will come
under three categories,
so it is important that
you pay attention to the
organization of your
Three categories of cutaneous lupus.
Cutaneous lupus is my topic, clear?
We’re not going to do
the full systemic here.
this is the one that you’re oh so familiar
with with the malar butterfly rash.
Is it affecting nasolabial type
of region right here, the SLE?
No, it does not.
You have another type.
Under cutaneous lupus is this called
subacute lupus erythematosus.
It’s annular erythematous,
and then it will be located
on the sun exposed skin.
Often involves the arms and the neck
because of exposure to the sun.
Associated with --
Please, make sure you
which is SSA antibody.
The last time you’ve seen this
was your Sjogren, wasn’t it?
You saw SSB, which
is your anti-La,
and SSA, which is anti-Ro.
May be caused by
thiazides or other meds.
We’re referring to subacute
What’s my topic?
Cutaneous lupus erythematosus.
So far, we looked
at two categories:
acute and subacute.
What do you think is left?
So, chronic cutaneous
What’s my behavior here?
indurated or scarred plaques;
chronic, chronic, chronic.
Most often affects the
face and the scalp.
And has a prediliction for African-American
women being most commonly affected.
My topic is cutaneous lupus erythematosus.
There are three categories.
The acute is the one that
you’re quite familiar with
with the butterfly malar rash.
Number two is the subacute, and
number three would be the chronic.
If you'd notice here, on your left is
acute systemic lupus erythematosus.
You have that beautiful
We call this malar or should
I say the characteristic.
You’ll notice here that the nasolabial
margin or fold has been spared.
Then we have the subacute cutaneous lupus
erythematosus, which is the middle picture.
And here, you’ll notice
the sun exposed areas,
either it’d be the arm, maybe the
chest in this particular patient.
And finally, you have your chronic
cutaneous lupus erythematosus.
This is the one in which -- please take
a look at the scalp of this patient,
and you’ll notice that
there is deep pigmentation
surrounded by areas that
or maybe perhaps, erythematosus.
Where else would you find this?
Maybe perhaps, on your face.
Most commonly, with chronic,
it would be which population?
An African-American lady.
The malar rash is
present with SLE.
The subacute type of cutaneous
may have systemic complications, and the
chronic has systemic complications.
A small percentage
of the time as well.
Here’s my acute,
all in terms of percentage
of systemic involvement.
Evaluation of systemic disease.
Always suspect lupus
You want to make sure that the
systemic organs are doing okay.
Referral to a dermatologist
We have steroids, and maybe perhaps,
antimalarials, and sun protection,
all being possible measures of
management of lupus erythematosus.
