Macroscopic Pathology Flashcards
Describe the lesion
- Focal
- Red
- Raised, well-demarcated
- Spherical
- Intra-lesion parasite
Focal: specific to a small, definite area
Describe the lesion
- Focally extensive
- Light brown
- Soft
- Circular
- Compressive (against cerebellum & cerebrum)
- Superficial
Describe the lesion
- Focally extensive
- Unilateral
- Gray with red areas
- Soft
- Well-demarcated
- Compressive (against the neural parenchyma)
Describe the lesion
- Multifocal to coalescing
- Spherical and amorphous
- Brown
Describe the lesion
- Yellow
- Diffuse
Hepatic lipidosis
Describe the lesion
- Unilateral
- Pale
- Inflammed
Unilateral fibrous pneumonia
Fibrin deposition = characteristic of acute lung injury
Describe the lesion
- Right, unilateral
- Cranial and lies distal to larynx
- Oval
- Solid
Possible thyroid tumor
Describe the lesion
- Enlarged (parathyroid)

- Perforated
2 ulcers present, and 2 separate perforations
- Inflammation
- Necrosis
- Mineral
- Keratin
- Fibrosis
- Urates
- Lipids
- Bone
What color is typically associated?
White
- Hemorrhages
- Congestion
- Hyperemia
What color is typically associated?
Red
- Inflammation
- Bilirubin
- Fat
- Myelin decomposition
- Meconium (newborn’s first poop)
- Fibrin
What color is typically associated?
Yellow
Icteric, jaundic
Pre-hepatic
Hepatic
Post-hepatic
- Biliary pigments
- Eosinophilic inflammation
- Necrosis
- Algae or fungi
- Hemosiderin (iron-storing protein)
What color is typically associated?
Green
- Melanin
- Blood
- Necrosis
- Fasciola species
- Exogenous carbon
What color is typically associated?
Black
What is a “depressed” outline?
“something was removed”
* necrosis
* hypoplasia/aplasia
* atrophy
What is a raised/widened outline?
“something was added”
* Fluid: edema or hemorrhages
* Cells: inflammation, neoplasia
* Gas: usually bacterial
Where do triangular and rhomboidal lesions typically originate?
From a vascular site
What is a cavitated lesion?
Lesions that have progressed to a more advanced stage
Pox
Neoplasia with fibrosis
Neoplasia = uncontrollable, abnormal growth of cells or tissues (linked to excessive cell proliferation)
Fibrosis = thickening of tissue due to healing/scarring process
What is a linear lesion?
Distention of a pre-existing anatomical structure
