apoptosis

What is it

Lipidosis (steatosis / fatty degeneration

Liver with macrovesicular lipidosis

Liver with microvesicular lipidosis

steroid hepatopathy

Glomerular disease - proteins in urinary space → hyaline droplets in tubular epithelial cells

Constipated» plasma cell (Mott cell; Russel bodies)

Viral inclusion bodies in the biliary epithelium of a dog (canine distemper virus)

Dystrophic mineralization

Yellow - Endocaedial surface

Red - Mineralization

Green- Viable myocardium

Lakes of mineral

Amyloidosis

Kidney, glomerulus

Gout

Carboxyhemoglobin

Methemoglobin

Intravascular hemolysis and hemoglobinuria

Liver with intracellular hemosiderin (brown granular material) in the cytoplasm of hepatocytes

Sidero-fibrotic plaque - very common change in dog spleen

Dog, lungs -chronic left-side heart failure → chronic congestion in the lungs → hemosiderophages in the alveoli

Heart -lipofuscin in cardiomyocytes -perinuclear yellow granularpigment deposits

pig

Lungs -anthracosis(carbon particles in the peribronchialarea, in the cytoplasm of macrophages)

liver, cystic biliary hyperplasia, multifocal

liver, cystic biliary hyperplasia, multifocal.

what happneed and etiology

Dog: Musculus frontoscutularis, musculus temporalis atrophy, unilateral.

Etiology: denervation

Gland with cavity, dilated → glandular epithelium has

transformed into squamous epithelium [metaplasia]

Ruptured cyst with inflammation surrounding the ruptured region

Neutrophils

Neutrophils

Siderophage

(black arrow)

Plasma cell

(yellow arrows)

Gland cavity - dilated, lined with squamous epithelium(red) [metaplasia] and in the lumen there are exfoliated acantholytic epithelial cells(green), debri, neutrophils(blue). Neutrophils also in the interstitium
