Reading Cytology Flashcards
2 types of neutrophils
Degenerative and nondegenerative
These neutrophils are hypersegmented
Degenerative
These neutrophils have 3-5 lobes
Nondegenerative
Oval cell with odd shaped nucleus, basophillic cytoplasm, and perinuclear clear zone
Plasma cells
Large cells derived from monocytes within the tissue. Oval with lacy chromatin, blue cytoplasm with vacuoles.
Phagocytes
Macrophages
Round with round to oval nucleus that may react to fluid and change shape.
Not to be confused with malignant changes and somewhat resemble macrophages
Mesothelial cells
Round to oval with numerous blue to purple cytoplasmic granules that contain histamine and heparin
Mast cells
These 3 cells look the same as they do within blood
- Lymphocytes
- Eos
- RBCs
Cells associated with inflammation
Neutrophils and macrophages
Can be mild, moderate, or marked
inflammation
Acute inflammation that may be due to bacteria
85% neutrophils, but may also see macrophages and lymphocytes
Purulent
Can be chronic or active inflammation due to parasitic or fungal infections
50% macrophages, 75% neutrophils
Pyogranulomatous
Chronic inflammation due to parasitic or fungal infections
70% monocytes, macrophages, and giant cells, few neutrophils
Granulomatous
When inflammation decreases, so does the number of
neutrophils
Inflammation due to parasitic infections or neoplastic disorders
>10% eosinophils, may also see mast cells, plasma cells, and lymphocytes
Eosinophilic
