Terminology
The study of tissues.
What is histopathology?
Technique used to obtain cytologic specimens from masses.
What is fine needle aspirate?
This instrument should be used to obtain the TP of an effusion.
What is a refractometer?
Type of lesion that consists of a homogeneous population of a single cell line.
What is neoplasia?
Normal physiologic response to tissue damage.
What is inflammation?
Malformation of tissue during development.
What is dysplasia?
The introduction of a needle into a body cavity to remove fluid.
What is centesis?
This type of effusion has a low cell count and low protein and is usually due to hypoalbuminemia.
What is transudate?
This type of neoplastic cell appears as separate cells with well defined cytoplasmic margins.
What is a round cell?
Type of inflammation characterized by > 85% neutrophils.
Increase in tissue size or function due to an increase in the number of cells.
What is hyperplasia?
Common method for obtaining tissue samples in dermatologic disorders.
What is punch biopsy?
This type of effusion has increased cellularity and protein content due to an inflammatory process.
What is exudate?
What is benign?
Associated with chronic inflammation, this type of inflammation is characterized by a large proportion of mature lymphocytes.
What is lymphoplasmacytic inflammation?
Unregulated cell growth independent of an external stimulus.
What is neoplasia?
Synovial fluid obtained from an arthrocentesis should be placed in this type of blood tube for cytologic evaluation.
What is an EDTA tube?
The wet form of this disease is associated with straw colored fluid that has a protein concentration > 3.5 g/dL.
What is feline infectious peritonitis?
Benign neoplastic lesion of epithelial origin.
What is an adenoma?
Type of inflammation associated with a foreign body that is characterized by >15% macrophages and the presence of neutrophils.
What is pyogranulomatous inflammation?
As an adaptation to a stimulus, one cell type substitutes for another.
What is metaplasia?
The power used to characterize the overall cellularity and cell composition during cytologic microscopic evaluation.
What is high power (400x)?
The presence of this pigment in the cytoplasm of macrophages is indicative of a hemorrhagic effusion that is a few days old.
What is henosiderin?
Variability in the size and shape of the same cell type that is present on a cytologic sample.
What is pleomorphism?
Due to nuclear swelling caused by endotoxins, the presence of this cell indicates bacterial infection.
What is a degenerative neutrophil?
