What causes multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?
NSAIDs or renal failure (uremia)
How do NSAIDs cause multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?
They inhibit prostaglandin which vasoconstricts the blood vessels and causes ischemia and necrosis
How does renal failure cause multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?
Phosphorus is not excreted and the imbalance causes and increase in calcium leading to calcification and necrosis

Transmural duodenal ulceration in a horse
Rim of congestion and more of a paler color (tissue necrosis) happens from the inside to outside when something erodes the mucosa
Transmural duodenal ulceration
Caused by parasitic migration through liver and lungs and results in white spotted livers in pigs and hemorrhage in other species

Enamel hypoplasia, peyer patch necrosis, stomatitis
What causes reticular lymphoma in a cow?
Bovine leukemia virus/retrovirus
Occurs in cats <3 years old due to aberrand immune response involving ++MOs
Multifocal granulomatous vasculitis/phlebitis/peritonitis/serositis
What is the etiology of multifocal granulomatous vasculitis/phlebitis/peritonitis/serositis?

Secondary to parasites, bacteria, viruses
Obstruction made mainly out of plant material
Obstruction made mainly from hair
What causes bilaterally symmetrical ulcerative glossitis?
Uremia from renal disease
