Now remember our diagnostic
criteria for lupus.
There are an extensive number of potential
manifestations that we might see with lupus.
It would be really rare for a patient to exclusively
have this malar rash with nothing else going on.
For the sake of review, recall that our diagnostic
criteria include this 4-Skin-RASHNIA mnemonic
in which we're looking for at least 4 of those systems
involved in order to consider the diagnosis of lupus.
Now, while our patient may have something that resembles
this classic butterfly rash of systemic lupus erythematosus,
the rash typically spares the nasolabial fold and
really should be accompanied by some other symptoms.
So we'll leave that one on our list but I
think it is lesser down on our differential.
