Descriptions and Diagnoses Flashcards
Catarrhal
Pattern of acute inflammation in which the tissue response consists of the secretion or accumulation of a thick gelatinous fluid containing abundant mucous and mucin from the mucous membrane
Describe the distribution
Locally extensive
Description
Describes what you see, precise word picture and not subjective
Cause
Poxvirus
Cause
Various bacteria
Suppurative
Pattern of acute inflammation in which the tissue response consists of the accumulation of fluid with a high concentration of plasma protein (specific gravity >1.02) and high numbers of leukocytes, predominately neutrophils
_____________________
Pus
Miliary
Type of multifocal where there are numerous pin-point foci
Black coloration can tell you?
Presence of melanin, fluke pigment, exogenous pigment (carbon), decomposition (hydrogen sulfide from digestion of blood by bacteria)
Disease name
Hardware Disease
A tissue that you can “spread with a knife” is likely due to?
Necrosis and exudate
Distribution
Way to state the pattern and extent of lesions present
Multifocal
Numerous similar lesions that can be of variable size
A well demarcated lesion tells you that the process that caused the lesion is
Gradually infiltrating into the normal tissue and is poorly contained
What can you tell about the route of spread of a locally extensive lesion?
Spread due to local introduction via penetrating wound or anatomic pathway
A well demarcated lesion represents a (different/same) tissue.
A well demarcated lesion represents a (different/same) tissue.
Green coloration can tell you what?
Presence of bile pigment, hemosiderin, eosinophils, algal or fungal infection.
What can you tell about the route of spread of a multifocal lesion?
Spread is embolic/hematogenous
EDx
Poxviral Dermatitis
How to record a description
“Clean Person” to take notes
Digital Images
Personal Recorder in bag
Describe the distributio
Diffuse
Translucent coloration can tell you?
Presence of mucus or parasite cysts
Features of an EDx
Cause
Origin
Pathological Process
Red coloration can tell you what?
Presence of Hemorrhage (focal), congestion (diffuse and patchy)
MDx
“Interprets” the description and makes subjective conclusions
Features of the MDx
Organ
Pathological Process
Distribution
+/- Chronicity
+/- Severity
Fibrinous
Pattern of acute inflammation in which the tissue response consists of the accumulation of fluid with a high concentration of plasma protein (specific gravity >1.02) and no to low numbers of leukocytes
Describe the distribution
Multifocal
Describe the distribution
Miliary
A lesion that is in straight lines tells you what about the cause?
Lesion is following an anatomic structure
A geometric shaped lesion tells you what about the cause?
The lesion involves the vasculature
A poorly demarcated lesion tells you that
The lesion and adjacent tissue may be similar
MDx
Heart - pericarditis, suppurative, diffuse, chronic severe
A well demarcate lesion can be caused by
Infarcts or chronic lesions with a fibrous capsue
A tissue that you can’t “spread with a knife” is likely
Viable tissue and cells
Describe the distribution
Multifocal coalescing
A raised lesion tells you what about the cause?
Something has been added
Focal
One isolated lesion
White coloration can tell you what about cause?
Presence of leukocytes, necrosis (soft), calcium, keratin (off-white), fibrin, connective tissue (firm), urates, lipid or bone.

Distribution
Shape
Color
Consistency
Margins/Surface
Yellow coloration can tell you what?
Presence of leukocytes, bilirubin, fat or fibrin
Diffuse
Throughout a large portion of the effected tissue
What can a symmetrical lesion tell you about the cause?
Indicates systemic or metabolic cause
A depressed lesion tells you what about the cause?
Something has been lost (necrosis) or the tissue has contracted
