ok, this is obviously lung tissue.
hx: 2 weeks ago had an MI. presents now with S3, dyspnea of exertion, and sleeps on top of 3 pillows at night
Going to throw this out there but it seems way too easy. Heart Failure cells?
not easy, you guys are just super geniuses. 😉
yup, hemosideren laden heart failure cells.

so wait, connect the dots for me between the multifocal encephalopathy and aschoff bodies?
at this stage of the condition...mcc of death would be due to what?
Can anyone point out where the caterpillar nucleus anitschkow cell is? Also, I thought aschoff bodies were kind of in a myxoid stroma/edematous looking background. I hope on the NBME question they at least gave you enough background to tell you were in cardiac tissue 😛
Yep, wickham's striae iirc
last one by me for the night...need to go read...but here you guys go...
two different individuals, just providing you two pictures of the same diagnosis
Subacute bacterial endocarditis.
combo together?
B2 deficiency:
The 2 C's : Cheilosis of the mouth and corneal vascularization.

Chlamydia

Kawasaki disease

I'll leave a hint, since I'm about to go to bed. Highlight below if you want the hint.
If the dermatological complication from this disease were found in adults, it would classically be in a necklace distribution.

rheumatic fever (erythema marginatum is shown)
Okay...here's my first contribution 😉
infant/young child with mental ******ation, short stature, and this skin finding:
Hartnup Disease.
That's the Dermatitis of Pellagra right there.
Middle-aged adult presents with systolic murmur radiating to carotids and anemia. What's the cause of the anemia?
Mechanical destruction...I think. Does this patient have a mechanical aortic valve, or just really bad stenosis?
A correct answer, but not the one I was thinking of. I'm a bad question-writer 😳
The anemia I was thinking of is coincidental with the cardiac defect (you're right, it's aortic stenosis). There would also be findings upon colonoscopy:
Hopefully that's enough of a hint without giving it away.

lol colon cancer with strep bovis? 😛 edit: didnt see the pic lol

Osler-Weber-Rendu
OK I had to go hunting, but this disease has been cemented in my memory now. I'd never heard of it before.
It's Heyde Syndrome.
yep 👍 aortic stenosis + vWF deficiency/angiodysplasia/iron-deficiency anemia (iirc it's in gunnertraining, but the name isn't listed, just the symptom associations)
side question: what's a good short-term pharmacotherapy for this, since the bleeding is due to low vWF (straight out of FA/pathoma)?
Desmopressin.

This finding plus this finding

equals what syndrome?

Crohn's: cobblestone + erythema nodosum
That's a good guess too, as is Gardner's
so close 😛 there's another slightly different syndrome that is the right answer (same family of mutation though). Turcot's would have medulloblastoma or malignant glioma instead of the second picture
clever, but this is erythema nodosum (classically on legs)
that's it! those are osteomas of the face/skull bones
clever, but this is erythema nodosum (classically on legs)
It's amazing how much book knowledge I've obtained for studying for this test but when used in a practical setting I'm just as likely to diagnose Lyme disease for Endocarditis for SJS for Crohn's if someone doesn't tell me what I'm looking at in words. Good job USMLE
+100000. As someone who never went to lecture, one of the biggest gaps in my knowledge is images. The lectures at my school sucked and left out tons of important, Step 1-testable material...but at least they had lots of pictures. And when you're in third year, knowing what things look like is just as important as knowing lots of facts about it. I think this thread is really important!
27 y/o male just immigrated from Africa shows up with painless ulcerations on his penis that he first noticed 1 week ago. Patient was started on a course of Penicillin G but returned 10 days later when there has been no improvement of his condition.
One of the ulcers is swabbed and the slide below is what is seen in the lab.
What is the arrow pointing to?
What is the disease?
What is the cause of the disease?
Why didn't Penicillin G cure the disease?
(sorry for the Giant picture, especially those of you on phones, but it's a good one and the smaller version lacked)

FAP + osseous tumors + rentinal hyperplasia?
wow, I have absolutely no idea what that is... damn.27 y/o male just immigrated from Africa shows up with painless ulcerations on his penis that he first noticed 1 week ago.

FA has it under FAP, same as turcot's. I've gotten enough of these questions incorrect that this is burned in my head
zzz. you are definitely right tiedyeddog/MLT2MT2DO. i thought i was remembering gunnertraining, but i just checked it again and i was wrong
no prob,
I think HPNCC/Lynch -> MSH2/MSH1/MSH6/PMS1+2. Doesn't always have polyps. Lots of other cancers.
FAP(and gardner's, turcot) -> APC. Always has hundreds of polyps.
