Used for different processes that we are performing
instruments
differentiate autopsy from biopsy
autopsy is the tissue examination of the dead, while biopsy is the tissue examination of the living
post mortem examination

“In situ” – in place dissection
rokitansky
“En block” – removal, removal of organs in same group/activity/region

types of biopsy
- Fine needle aspiration
- Core needle
- Incisional
- Excisional
- Punch
- Shave
- Curettage
Simplest, least invasive
fine needle aspiration
Uses slightly larger needle, 1/16 inch in diameter, ½ inch long
core needle
Surgical, small part of a large lesion or tumor is taken
incisional
Surgical, entire affected area is taken
excisional
For skin, uses circular blade to obtain deeper skin sample that removes a short cylindrical core of tissue, apple core
punch
For skin, small fragments of outer layers of skin are “shaved” or scraped
shave
Tissues are removed from body cavity (or canals) using a currette
curettage
methods of examination
fresh
fixed
