jeporady Flashcards
This can be seen in both female dogs and cats.
pyometra
This disease is seen often in puppies in our ES.
Parvoviral enteritis
feline panleukopenia- punched out peyers patch
Found during an autopsy of a pig.
can’t peel off
Fibrinous/fibrinosuppurative pleuropneumonia
From the lung of a foal (lesion and cause).
Pyogranulomatous pneumonia caused by Rhodoccous equi
A “surgical emergency”
Histocytoma
will regress on its own
When you find one congenital anomaly, always look for another…
Palatoschisis (cleft palate) and Ventricular Septal Defect (VSD)
Don’t look a gift horse in the mouth.
Severe malocclusion – “wave mouth”
Not all masses are bad.
Pancreas – nodular acinar/exocrine hyperplasia &
Liver – nodular hyperplasia
This represents a chronic lesion.
Liver – cirrhosis
Horse, penis – squamous cell carcinoma
This is commonly seen in older small dogs
Mitral valve endocardiosis (with left atrial fibrosis due to regurgitation)
smooth, shiny, nodular
murmur, jet lesions, atrial dilation: eccentric hypertrophy, thrombosis, chordae tendineae rupture, atrial rupture
DEGENERATIVE LESION
King Charles Cav or older dogs
ENDOCARDITIS= aortic, friable, red →thrombosis, bacterial/ inflammation
can lead to ischemia and infarct in kidneys
An important thing to notice in an abdominal explore
Peritoneal cavity – carcinomatosis
cat heart
Hypertrophic cardiomyopathy (HCM)
big heart
thick LV wall = ↓ volume (concentric hypertrophy- from pressure overload), left atrial dilation and thrombosis
Eating is important.
Bone marrow – serous atrophy of fat; Heart – serous atrophy of epicardial fat
Triangles of death.
Kidney and spleen – acute infarcts
One possible cause of this lesion.
big meaty
Diffuse splenomegaly (“meaty spleen”)–
chronic infectious disease, prolonged bacteremia/septicemia
chronic hemolytic anemia
diffuse granulomatous disease
disseminated follicular hyperplasia
neoplasia (lymphoma)
storage material
extramedullary hematopoiesis
Cat. Write the pathogenesis. Start with the morphologic diagnosis of lesion A followed by the steps to get to lesion B. Use arrows!
Lesion A: unilateral thyroid gland hyperplasia (adenomatous hyperplasia)
Lesion B: aortic thromboembolism (“saddle thrombus”)
PG: Adenomatous thyroid gland hyperplasia – increased thyroid hormone production (hyperthyroidism) – increased production of myocardial contractile proteins – myocardial hypertrophy (thyrotoxic cardiomegaly) – turbulent blood flow – cardiac thrombosis - thromboembolism lodges in distal aorta – aortic (“saddle”) thromboembolism
