__________ is a way to state the pattern and extent of lesions present.
Distribution
Which type of distribution means “throughout a large portion of the effected tissue” ? A. Focal B. Multifocal C. Diffuse
C. Diffuse
Which type of distribution means “one isolated lesion” ? A. Focal B. Multifocal C. Diffuse
A. Focal
Which type of distribution means “numerous similar lesions that can be of variable size” ? A. Focal B. Multifocal C. Diffuse
B. Multifocal
______ is a type of ‘multifocal’ where there are numerous pin-point foci
Miliary
Name this type of lesion distribution:
Multifocal-coalescing
Note: numerous raised nodules that often appear in groups on the skin surface of the knees, elbows, and lower extremities. The nodules coalesce to form a large patch that appears to be a single lesion.
Name this type of lesion distribution:
Locally extensive
Name this type of lesion distribution:
Diffuse
Name this type of lesion distribution:
Multifocal
What can the distribution of a lesion tell a pathologist/ clinician ?
- The route of spread of the disease 2. If symmetrical - the systemic/metabolic cause of the lesion
An ascending lesion means ? A. Coming from the urine up B. Coming through the blood
A. Coming from the urine up
A descending lesion means ? A. Coming from the urine up B. Coming through the blood
B. Coming through the blood
What can a geometrically shaped lesion of an organ tell you? A. The lesion is following an anatomic structure (blood vessel, bronchiole, nerve etc…) B. Something has been added (edema, blood, inflammatory cells, neoplastic/hyperplastic cells) C. The lesion involves vasculature D. Something has been lost (necrosis) or the tissue has contracted (connective tissue)
C. The lesion involves vasculature Note: •Geometric (triangle, diamond, wedge, rhomboid, circles) – the lesion involves vasculature •Straight lines – the lesion is following an anatomic structure (blood vessel, bronchiole, nerve etc…) •Raised – something has been added (edema, blood, inflammatory cells, neoplastic/hyperplastic cells) •Depressed – something has been lost (necrosis) or the tissue has contracted (connective tissue)
A translucent colored lesion is usually characteristic of what ? A. Hemorrhage B. Fibrin C. Mucous D. Bilirubin
C. Mucous Note: Hemorrhage -> Red color Fibrin -> White color Bilirubin -> Yellow color
Melanin, fluke pigment, exogenous pigment (carbon), decomposition (hydrogen sulfide from digestion of blood by bacteria) are ALL characteristic of what color lesion ? A. Translucent B. Black C. Green D. Yellow
B. Black
What is an infarct ?
A small localized area of dead tissue resulting from failure of blood supply.
If the margin of the lesion is well demarcated what can it tell you? A. The lesion represents a different tissue (tumors) B. The process is gradually infiltrating into the normal tissue C. The lesion is poorly contained
A. The lesion represents a different tissue (tumors)
Give a MDx for this picture:
MDx: Heart – pericarditis, suppurative, diffuse, chronic, severe
Cause – various bacteria
Disease name: Hardware disease
What is the Etiological diagnosis of this image/lesion ?
EtDx – poxviral dermatitis
