16
Q

what should be done after a cytology if there is a possible bacterial neutrophilic infection

A

culture

bacteria could mean septicemia

17
Q

if there is no bacteria present with the neutrophilic inflammation, what may cause this problem

A

trauma, viral, immune mediated, necrotic tumor

18
Q

what cells are involved with pyogranulomatous inflammation

A

neutrophils
macrophages

19
Q

what are ways to name a pyogranulomatous inflammation

A

chronic neutrophilic
mixed neutrophilic histiocytic

20
Q

what should you expect to see on a slide with a pyogranulomatous inflammation

A

neutrophils but with increased numbers of macrophages

21
Q

what are the ways a macrophage may present in response to injury

A

epithelioid macrophages
binucleated/ multinucleated giant cells
mitotic figures

22
Q

true or false:
presence of macrophages can show features that suggest malignancy and is always cancer

A

false
if there are signs of inflammation, it is not cancer

23
Q

what are some causes of pyogranulomatous inflammation

A

lick granuloma
foreign body reaction
infectious disease

24
Q

what are some infectious diseases that can cause pyogranulomatous inflammation

A

filamentous bacteria
fungal organisms
FIP

25
Q

what is another term for lymphocytic inflammation

A

lymphoid hyperplasia

26
Q

what is seen on a cytology of a lymphocytic inflammation

A

predominance of lymphocytes

27
Q

what are the looks of lymphocytes in response to antigenic stimulation

A

reactive lymphocytes
plasma cells / Mott cells
large lymphocytes / immature

28
Q

what are some causes of lymphocytic inflammation

A

injection site (vaccine)
foreign body
arthropod bites
cutaneous lymphoma

29
Q

what cells would you see on an eosinophilic inflammatory cytology

A

30
Q

which species has round eosinophils with variably sized granules

A

dog

31
Q

which species has small, rod-shaped granules in the eosinophils

A

cat

32

A

horse

33
Q

what are some causes of eosinophilic inflammation

A
