This document summarizes an online oral pathology conference presentation. It discusses the process of specimen examination from biopsy to diagnosis. Key steps include gross examination of the biopsy, fixation, processing, embedding, sectioning, staining, and examination under a microscope. The presentation provides examples of an oral pathology case that was diagnosed as Epithelial-myoepithelial carcinoma. It also includes links to videos and an interview that further explain oral pathology in practice.

4. First : Questions

5. Second (introduction) : Pathology is the study of the
nature and causes of diseases it underpins every
aspect of medicine , from diagnosis to monitoring , and
vital for research .

6. Third : The process
picture that summarize process
• First The biopsy was taken by the surgeon .

7. • After taking the specimen these are the steps
done in lab.

8. 1- Gross specimen examination:
the pathologist will examine the specimen , measuring
its size , describing its color and texture and determining
if any masses are present .

9. 2- Fixation : the process where tissues are treated with agents
that retard the alteration of tissues , meanwhile normal
anatomical structures is maintained

10. 3-Processing: remove the water from the tissues and replace
with a medium that soldufies to allow thin sections to be cut

11. 3-Tissue embedding: the processed tissue is then embedded
in hot wax to form a tissue block . When the block hardens , it
is stable at room temp. indefinitely

12. 4-Sectioning : is cutting the specimen in sections using a
microtome ( so the sections are very thin) depending on the type
of microscope that we will use the instrument used to cut the
specimen will be different

13. 5- Mounting: is placing the specimen on microscope slides (glass
slides )

14. 6- Staining the section :provides visual contrast
and may help identifying specific tissue
components

15. So the final diagnosis of this case was ( Epithlial-
myoepithlial carcinoma)

16. This is a video that summaries every thing:

17. An interview done with Dr. Manal Al-Sheddi Associate Professor

18. In summary :If Pathologists didn't exist ,
where would the answers come from ?
So, without pathologists , any answers
found would be questionable .
