Intro to pathology and morphological diagnosis

any detectable deviation from the normal range is known as what?

disease

What are the 4 main aspects of disease

• cause(etiology)

• pathogenesis

• morphologic changes

• functional consequences

What are the two types of etiology known in diseases

• intrinsic

• extrinsic

What are primary intrinsic etiologies of disease

• genetic mutations

• breed predispositions

What are secondary intrinsic etiologies of disease

• age

• sex

• species

a patient specific etiology is an intrinsic etiology known as what

idiosyncratic

what are extrinsic etiologies of disease

• pathogens/animate agents

• inanimate causes

The sequence of events from start to end of a disease is known as what?

pathogenesis

A visible manifestation of disease is known as a _________?

lesion

when visualizing a lesion from macroscopic to microscopic what types of pathology would you use

• gross pathology

• histopathology

• ultrastructural pathology

knowing the type or pattern of a lesion allows for the clinicians to do what?

• identify a cause

• define a pathogenesis

• establish a diagnosis

• make a prognosis

if a lesion is larger than normal it generally means what?

something added

if a lesion is smaller than normal it generally means what

something removed

A lesion that is so unique that it can only be caused by one etiologic agent is known as ____________

pathognomic

What are the different types of biopsy

• punch biopsy

• wedge biopsy

• excision biopsy

a prediction of future outcomes is known as a what

prognosis

to make a morphologic diagnosis what parts are necessary to include

• affected structures(organ)

• process(nature of lesion)

• distribution

• severity

• time course

What type of diagnosis is this:

encephalitis, severe, chronic, diffuse

morphologic diagnosis

A diagnosis that names the cause or agent of the disease is known as a __________ diagnosis

etiologic

what type of diagnosis is this:

mycotic gastroenteritis

etiologic diagnosis

simply seeing the name of a disease you can conclude that a doctor gave you what type of diagnosis?

disease diagnosis

name the distributions of disease provided by the picture

1. locally extensive

2. multifocal

3. diffuse

4. focal

what are the 4 levels of lesion severity

1. minimal

2. slight

3. moderate

4. marked

5. severe

what are the non inflammatory natures of lesions

• degeneration

• pigmentation

• mineralization

• disturbances of growth

• neoplasms

• displacement of viscera

generally inflammatory processes will end with what suffix

itis
