Reactive Lymph Node/ Lymphadenopathy
Characterized by lymphoid cell hyperplasia, sinus plasmacytosis, histiocytosis and erythrophagocytosis.

What is wrong with this????

Nothing! It is a normal esophagus of a leatherback turtle
The esophageal mucosa of leatherback sea turtles has large spines which point caudally to facilitate the swallowing of pray.

Tell me atleast two things wrong with this horse

Ileal muscular hypertrophy (ideopathic or due to parasite impation) –> stenotic lumen
Anoplocephala perfoliata infection at the ileocecal valve

Infected animals: chronic diarrhea and stunted growth
“garden hose appearance”

Etiology: Lawsonia intracellularis
CONFIRM DIAGNOSIS VIA SILVER STAIN

Horse. Etiolgy? MDx?

MDx: Erosive and ulcerative gastritis
Etiology: blister beetle (cantharidin) toxicity (found in alfalfa hay)
Feline

Feline Fatty Liver Syndrome - Hepatic Lipidosis
Mdx: Diffuse hepatic lipidosis
Description: rounded edges, pale, floats in fluid
Important condition in cats that go off feed.
Pig
Dz? MDx?

Hepatosis Dietetica- Vitamin E/Selenium Deficiency
Mdx: Diffuse Panlobular hepatic necrosis ***
(not really inflammatory)

Dog. Mdx?

MDx: Chronic hepatitis with post-necrosis scarring and nodular regeneration// Hepatic Cirrhosis
Pale color is due to fatty changes within the regenerative nodules.
Cow. Mdx? Etiology?

Mdx: Chronic eosinophilic and granulomatous hepatitis with interlesional flukes (Fascioldes magna)

Dog.

Hepatic rupture/fracture
common in HBC cases. May result in fatal hemoperitoneum.
Cow

Mdx: Diffuse chronic passive hepatic congestion
Nutmeg liver/ Cardiac cirrhosis due to right sided heart failure
Looks enlarges, mottled (congestion and fatty changes), fibrotic, nodular
Cat Liver. Mdx? Etiology?

Mdx: Chronic Cholescystitis and cholangitis/peri-cholangitis, multifocal, mild to moderate with intralesional trematode parasites
Platynosomum fastosum =Liver Fluke
See promoinant appearance of bile ducts. May cause hyperplasia of the bile epithelium and thickening of the duct walls

Rabbit
NEED TO KNOW

**Mdx: Proliferative (hyperplastic) cholangitis/cholangiohepatits**
**Etiology: Eimeria steidae**
**Edx: Hepatic coccidiosis**
One of the major diseases in rabbits (along with uterine carnoma and snuffles)
See pale, slightly raised areas that are scattered throughout the liver (surface and parrencyma).
Histology shows prominant fold of epithelium =hyperplastic

Calf Bone Marrow? Any lesions?

Normal for the age of animal
————————————-
(if adult, this would be considered bone marrow hyperplasia)
Mdx? Etiology? What other lesions would you see?

Mdx: fibrinonecrotizing enteritis
Etiology: parvo virus
Associtaed lesions: bone marrow and lymphoid depletion
Dx?

Metastatic melanoma
indicated by the black color and infiltration of the bone
on radiograph there will be a mass and decreased mineralization
tumor spread via both the blood and lymphatics
Dx?

Hemangiosarcoma
very hemorragic and infiltratinf the bone
Llama. Mdx? Dz?

MDx: multifocal granulomatous osteomyelitis
Dz: Tuberculosis
also see serous atropy of fat
Goat. Dx?

lymphosarcoma
————-
red marrow and white fat is being displaced along the medullary cavity and by a more yellow color tumor tissue near the epiphysis
