A 62-year-old woman comes to the physician because ...
why not systemic scleroderma since i did this question wrong and i chose systemic sclerosis scleroderma , can someone explain that ?
My best guess answer to that @luke.10 is that:
a) there's no mention of any skin involvement (which there would be in order to be scleroderma)
b) Scleroderma shows pitting in the nails, not clubbing
c) There would be collagen deposition with fibrosis, not hypertrophy of the bone at joints
Saying that, I also got this wrong! (but put RA...) so I'm not claiming to "get this" Hope my thought process helps, though!
This is in FA 2019 page 229
I agree with @kernicterusthefrog on this one, Bronchogenic carcinoma = lung cancer. Squamous cell carcinoma gives you hypercalcemia (new bone formation; maybe?), commonly found in SMOKERS ...
it's just bronchogenic ca, type of adenoca, which is classically associated with 'hypertrophic osteoarthropathy'
To get it for the test, remember that lung adenocarcinoma is associated with clubbing.
Mechanistically, this woman probably had RA. Then she was exposed to asbestos. The asbestos in the context of RA lead to caplan syndrome. The asbestos also triggered her bronchogenic carcinoma.
Then why isnt Rheumatoid Arthritis right? what comes first? bronchogenic carcinoma or rheumatoid arthritis?
