DISSECTION/EVISCERATION TECHNIQUES
GHON ROKITANSKY LETULLE VIRCHOW
34
One by one removal of organs Most widely used
VIRCHOW
35
"In situ" (in place) dissection, followed by en bloc removal
Rokitansky
36
"En bloc" removal Organs of same group/activity/region are removed at the same time
Ghon
37
"En masse" removal of organs All organs are removed at the same, then dissected by blocks
Letulle
38
Prerequisites:
•Written or informed consent from the legal next-of-kin • Medical abstract or clinical data • Autopsy Request (suspicious evidence of foul play)
39
Personnel
CPD Coroner Prosector Diener
40
A public official who is empowered to order an inquest into the manner or cause of death
Coroner
41
• Pathologist who performs the dissection
Prosector
42
Comes from the German word "leichendiener" meaning "servant of the dead"
Diener
43
Diener Comes from the German word "_____" meaning "servant of the dead"
leichendiener
44
Assists during an autopsy, and assumes many and varied responsibilities in the autopsy laboratory
Diener
45
(____= before;____ = death)
ante mortem
46
TYPES OF BIOPSY
Fine needle aspiration Core needle Incisional Excisional Punch Shave Curettage
47
• Simplest, least invasive Minor type of getting tissue sections • Uses very thin needle attached to a syringe to take out a small amount of fluid and tissue from area
Fine needle aspiration
48
• Uses slightly larger needle
Core needle
49
Remove small column of tissue (1/16 inch in diameter, (½ inch long)
Core needle
50
• Surgical • Small part of a large lesion or tumor is taken
Incisional
51
• Surgical • Entire affected area is taken
Excisional
52
• For skin Uses circular blade to obtain deeper skin sample that removes a short cylindrical core of tissue ("apple core")
Punch
53
• For skin • Small fragments of outer layers of skin are "shaved" or scraped
Shave
54
• Tissues are removed from body cavity (or canals) using a currette
Curettage
55
Methods of Examination
Fresh Fixed
56
What are the processes which are performed in histopathologic techniques
Tissue processing Cytology Frozen biopsy Immunohistochemistry Special staining
57
What phase is the tissue processing
Pre analytic
58
Autopsy comes from the GREEK word
Autopsia Cadaverum

Yuh
68
Requested during intra-operative procedures to help the surgeon in choosing his next plan of action

(-10 to -30 degree Celsius)
70
Which has better quality slides? Fresh or Fixed?
Fixed
71
Which histopathologic examination is faster? Fixed or Fresh?
Fresh
