normal or abnormal?

normal bone marrow biopsy

aplastic anemia

BONE MARROW BIOPSY WITH METASTATIC CANCER
describe the RBCs here

normocytic, have a zone of central pallor about 1/3 the size of the RBC. They have minimal variation in size (anisocytosis) and shape (poikilocytosis). A few small blue platelets are seen.
what cell is pointed out here? is it normal or abnormal?

A normal mature lymphocyte is seen. An RBC is seen to be about 2/3 the size of the nucleus of a small lymphocyte.

Increased reticulocytes /polychromatophils

ringed sideroblast, abnormal. Found in lead & zinc poisoning, ethanol toxicity, INH treatment, copper or pyridoxine deficiency, MDS
normal or abnormal neutrophil?

normal
normal or abnormal neutrophil?

abnormal. hypersegmented
what type of anemia

iron deficiency anemia (microcytic, hypochromic)
with increased fragility of RBCs, defect in erythrocyte cytoskeleton. what’s the disease?

hereditary spherocytosis
normocytic anemia, abnormal polymerization of spectrin. what’s the dx?

essential thrombocythemia
what’s the translocation associated with abnormal transformation of a pluripotent bone marrow cell resulting in prominent neutrophilic leukocytosis
