RBC cytoplasmic inclusion commonly seen in thalassemias, anemia of chronic disease, iron deficiency, and lead poisoningaggregations of RER and ribosomes
name the neoplasm of plasma cells presenting with hypercalcemia, renal insufficiency, anemia, & lytic bone lesionsoften see rouleaux (a sign of elevated protein) on peripheral smear
name the AML class: inversion (16). good prognosis, 'trash mouth'gum infiltration, sometimes DIC. good prognosis.
Neutrophils' primary granules contain myeloperoxidase, lysozyme, elastase. What do secondary granules contain? eosinophil granules contain peroxidase, & major basic protein. basophils' contain histamine & heparin.
name the disorder: blue people, single aa mutation in Hb shifts the plane of heme & causes oxidation of FeNOT methemoglobinopathy! that is 2-2 a mutation of reducing enzymes, not Hb itself
name the pathology: soccer ball cells in PBSmost common blood cancer, older folks, anemia & thrombocytopenia; also likely to see smudge cells
this factor does not cause bleeding but does prolong PT/PTT. identified w/ DRVVT and hexagonal phase phospholipid neutralization test.misnomer: not an anticoagulant in vivo, and not always associated w/ lupus.
vWF deficiency is a common inherited bleeding disorder. type 2 is a qualitative defect; types 1 & 3 are quantitative. which is more severe, type 1 or type 3?this is the autosomal recessive form (with 2N). treatment w/ DDAVP, synthetic vasopressin, is more effective in type I.

Name the AML class: translocation (8;21), most common subclassAML with maturation. good prognosis for AML.
Patient w/ sickle cell disease has MCA flow rate lower than 170 cm/s. Good sign or bad sign?High flow velocity means there's a smaller diameter due to partial obstruction. Fast flow = stroke risk. Transfusions lower velocity & stroke risk.

Favorable mutation in CLL: deletion of short arm of this chromosomedel(11q), del(17p), or t(11q;various) worsen prognosis. Trisomy 12 or the lack of detectable mutation are neutral prognostically.
