Cytology & Inflammation Flashcards
true or false:
cytologic diagnosis is based on large populations of cells
true
what are the questions you should ask yourself for a diagnosis list if there is inflammatory cells found on a slide
type of inflammation
are there organisms
if there are tissue cells found on a cytology slide, what questions should you be asking yourself
type of tissue
benign v. malignant
what are the types of tissue cells
epithelial
mesenchymal
round cells
which cells originate in connective tissue
mesenchymal
what are the types of white blood cells
neutrophils, lymphocytes, moncytes/macrophages, eosinophils
in what situations would you expect to see an increased presence of eosinophils
parasites
allergies
what cell(s) are involved in neutrophilic inflammation
neutrophils
what are the ways to name neutrophilic inflammation
acute/ active
purulent
suppurative
what are the normal aging changes of neutrophils
young
old
dead
what type of neutrophils are ‘band’ neutrophils
immature / young neutrophils
in what age stage of neutrophil would you expect to see segmented neutrophils
old neutrophils
in what situation would you expect to see degenerate neutrophils
in response to injury
how can you identify if a neutrophil is degenerative and in response to an injury
nuclei swelling
what is the typical cause of a neutrophilic inflammation
bacterial infection
what should be done after a cytology if there is a possible bacterial neutrophilic infection
culture
bacteria could mean septicemia
if there is no bacteria present with the neutrophilic inflammation, what may cause this problem
trauma, viral, immune mediated, necrotic tumor
what cells are involved with pyogranulomatous inflammation
neutrophils
macrophages
what are ways to name a pyogranulomatous inflammation
chronic neutrophilic
mixed neutrophilic histiocytic
what should you expect to see on a slide with a pyogranulomatous inflammation
neutrophils but with increased numbers of macrophages
what are the ways a macrophage may present in response to injury
epithelioid macrophages
binucleated/ multinucleated giant cells
mitotic figures
true or false:
presence of macrophages can show features that suggest malignancy and is always cancer
false
if there are signs of inflammation, it is not cancer
what are some causes of pyogranulomatous inflammation
lick granuloma
foreign body reaction
infectious disease
what are some infectious diseases that can cause pyogranulomatous inflammation
filamentous bacteria
fungal organisms
FIP
