Pathology Historology Flashcards
Abnormal azurophilic primary granules

Toxic granules - Sepsis (severe infection)
Patches of dilated ER that appear as sky-blue cytoplasmic puddles

Dohle bodies - Severe infection
Distinctive needle like azurophilic granules found in myeloblasts

Auer rods - AML, NHL, Thyroid cancer
Scarrered macrophages with abdundant wrinkled greenblue cytoplasm

Sea-blue histiocytes - CML
Small lymphocytes disrupted in the process of making smears

Smudge cells - CLL
Large cells with multiple nuclei or a single nucleus with multiple nuclear lobes

Reed Sternberg cells - Hodgkin cell
Nuclear remnants are phagocytosed by interspersed cells with abundant clear cytoplasm or lipid droplets

Starry sky pattern - Burkitts lymphoma
Cells found in adult Tcell lymphoma which appear to have multilobulated nuclei

Cloverleaf or flower cells - Adults t-cell lymphoma
Destructive plasma cell tumors involving axial skeleton

Plasmocytoma - Multiple myeloma
Multiple nuclei, prominent nuclei, and cytoplasmic droplets containing Ig

Bizzare multinucleated cells - multiple myeloma
Fiery red cytoplasm

Flame cells - Multiple myeloma
Pink cytoplasmic inclusions

Russell Bodies - Multiple myeloma
Blue globular nuclear inclusions
Dutcher bodies - Multiple myeloma
M proteins causes RBCs in PBS to stick in linear arrays

Rouleaux condormation - Multiple myeloma
Erythroblasts with ironladen mitochondria visible as perinuclear granules

Ringed Sideroblasts - Sideroblastic anemia, INH, Lead, copper poisoning, Multiple myeloma, RA, B6 deficiency
Neutrophils with only two nuclear lobes

Pseudo-pelger Huet cells - MDS
Megakaryocytes with single nuclear lobes or multiple separate nuclei

Pawn ball megakaryocytes - MDS
Premature release of nucleated erythroid and early granulocyte progenitors

Leukoerythroblastosis - Primary myelofibrosis
Cells that were probably damaged during the birthing process in the fibrotic marrow

Tear drop cells or dacryocytes - Primary myelofibrosis
Pentalaminar tubules often with a dilated terminal end or tennis racket like appearance

Birbeck granules - Langerhans cell histiocytosis
Small yellowbrown, brown or rustcolored foci in the spleen

Gandy gamma nodules - Splenic congestion
Small hyperchromic RBC lacking central pallor

Small dark nuclear remnants present in RBCs of asplenic patients

Howell Jolly bodies
Membrane bound precipitates on denatured globin chains

Bite cells - G6PD
