Just normal everyday blood agar. Giving a clinical vignette would make this uber easy, why I'm trying not to give it.

For those not seeing anything, I'd recommend moving your screen back and forth. Hint: Blood agar is usually a lot more red than that picture.
I'm afraid this will give it a away but, it is associated with kidney stone(s)
Yes this is proteus. This is the appearance of swarming on an agar plate. If you look you can see small pin point colonies in the middle of the swarming.
This is classical, though it may be not one of the most obvious cases of it.
I see it now. Thank you sir
Id say recent trip to Asia b/c Im seeing a granuloma w/ caseuos necrosis. I think a granuloma from a while back would be calcified. Unless she happens to be reactivating the infection she got form columbia.

What is associated with this skin finding?
Those are hypopigmented spots, looks like ash-leaf spots. tuberous sclerosis is associated with those.
What is associated with this skin finding?
rhabdomyoma of the heart - 100% predictive
angiomyolipomas of the kidney
angiofibromas aka adenoma sebaceum
mental ******ation
all of this assuming those are the hypopigmented ashleaf spots
Whoops, I changed to another link.

Looks like tinea corporis??? I was initially thinking lyme disease but I don't think they look like that.
Would you see fungi on a KOH prep?
wait if you find ash leaf spots there is 100% chance of rhabdomyoma?? Is that in FA?

This lesion doesn't involve fungi. Hint: its a sign for something to come a few days later.

Left one is foreign body then?
Yes, the one on the right has 'central clearing' b/c the lipids in the microbe's cell wall push the nuclei to the side.
Great explanation, ty. Wanted to make sure I understood correctly.
to keep the skin conditions going...what would you call this nose and what disease is it associated with?
The only thing that comes to mind is lepromatous leprosy or Rosacea, but I don't know about the redness seen in the picture... any other hint?
never heard of it, awesome post!!!
Serial x-ray over time, left is oldest, right is newest.
what disease causes this? I believe this is PIP joint.

is that the beginning of "pencil in a cup deformity", as in psoriatic arthritis?
something a lot more common.
this deformity is commonly associated with it, but not specific for it.
Forgot to reply -
it def works, just too content bloated in its current form. If they made a decent HY option, they'd have a killer set up

Answer is RA - I think that picture was either in pathoma or in my classes, can't remember.... but: no osteophyte or sclerosis, joint narrowing seems to be +/-.
The finger is a swan neck or boutonniere deformity. Not specific for RA, occurs in diseases with elevated ESR.
didn't see your reply at first, good call. I bet you're going to destroy Step, you've had some great responses in here.
