1. Contact Dermatitits – Type IV hypersensitivity
delayed type hypersensitivity regulated by T cells specifically CD8
TB test
CD4 T cells recognize antigen and present it with Class II MHC
2. Hypercalcemia, slow growing squamous cell tumor, Put together with
Histology:
Well differentiated: cells with eosinophilic cytoplasm due to
keratinization,
keratin/squamous pearls, intercellular bridging
Metaplasia of bronchial epithelium (picture will
Tends to cavitate
, 3. Medical student who swells when stressed out over test C1 esterase
inhibitor deficiency
Complement deficiency that is genetic. LARGE amount of swelling.
Causes hereditary angioedema. Releases vasoactive compounds= major
edema.
STRESS causes it to burst out
4. 1% percent can get B cell proliferation can get a B cell lymphoma -
SJOGRENS disease
Know ANA for Sjogrens, SLE, Scleredoma
Sjogern- causes dry eyes and dry mouth causes B cell lymphoma Anti-
ss-A Anti-SS-B
SLE- dsDNA and SMITH
Scleroderma- ScL-70 and anticentromere antibody
5. Woman with AIDS dementia, which of the following is suspected in
disseminating HIV to brain? MACROPHAGE
6. Stage of inoperability question. What tumor do you have the best chance
of removing to make a full revover? Best answer Squamous cell
carcinoma 4cm from carina (b/c small cell carcinoma is way too close to
close to caranina for margins? Everything else is in stage 4.)
2 choices to pick from, not sure which is right:
a) 2.8 cm Squamos Cell Carcinoma 4cm from Carina – this is the right
answer smaller the cancer the better the farther from the carina the better
b) 2.5 cm Small Cell Carcinoma 4cm from Carina- this is inoperable
7. Infant with eczema and thrombocytopenia had WISCOTT ALDRICH
SYNDROME
delayed type hypersensitivity regulated by T cells specifically CD8
