2. What is pathology ?
3. What do pathologists do?
The course
• Two credit hours course
• Three main subjects will be covered:

Course design!
topic instructor No of lectures Book chapter
Cell injury Dr Heyam Awad 5 1
Inflammation and repair Dr Mousa Abbadi 10 2

My lectures
• Two sets of slides:
• 1.A detailed one which you need to study from
This will be on my web page and on the e learning site before the lecture day .
2. A FUN version that includes mainly pictures.. This will aid us discussing the subject
Do we need sheets?.. How to study?
assessment
*Mid term.. 40 marks ..Around week 7material: cell injury and inflammation
*Final exam.. 50 marksmaterial: repair and neoplasia
*Attendance marks.. 10please note: school of medicine is strict
about attendance..
The best way to deal with my lectures!
• 1. attend the lectures and try to understand
• 2. read the slides carefully.. They are detailed.. I put everything you need for the exam there

What is pathology?
• Patho = disease
• Logy = study
• So pathology is the study of disease =علم االمراض
Pathology studies three main aspects of the disease process:
• Etiology
• Pathogenesis
• morphology
Etiology.. The “why” question
• = the origin of disease= the underlying cause.
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 ?
morphology
Histopathology is fun..
What do pathologists do?
Sample obtained.. how
Sample received in lab
HOW DOES THESE SAMPLES CHANGE INTO GLASS SLIDES???
Grossing = cutting the sample
Processing to a paraffin block
Cutting.. By a microtome
Staining the slide
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.
