Pathology studies three main aspects of the disease process:
• Etiology
• Pathogenesis
• morphology
Etiology.. The “why” question
• = the origin of disease= the underlying cause.
![Page 12: PATHOLOGY - JU Medicine€¦ · LECTURE 1 Introduction to pathology. Today’s lecture • Introduction aiming at: 1.Introducing you to the course. 2. What is pathology ? 3. What](https://reader030.fdocuments.in/reader030/viewer/2022040305/5ead3dd576fb1f193005f402/html5/thumbnails/12.jpg)
Pathogenesis.. “HOW”
• Steps in the development of disease.
• Describes how etiologic factors trigger cellular and molecular changes that give rise to functional and structural abnormalities.
• Disease occur in a multistep organized fashion..
pathogenesis
• Message: as a doctor you need critical thinking, splitting things into precise steps and stages

morphology
• The changes seen on tissues and organs that help diagnosing the disease
• Gross= macroscopic morphology: changes seen by naked eye
• Microscopic morphology: changes seen under the microscope.
Gross morphology .. Can you describe ?

Ready to be read by the pathologist
The pathology report
• We convey what we see under the microscope in a written report.
• The report includes macroscopic ( gross) and microscopic description.
• It gives you information about: the diagnosis, the prognosis and probably the underlying cause.
