Core Needle Biopsy
The lesion will be sliced ans a portion will be removed
Incisional biopsy
Removal f the entire area in question
Excisional biopsy
This is a primary technique for obtaining diagnostic full-thickness skin sample of 3-4 mm of cylindrical core of tissue sample is collected
Punch biopsy
Small fragments of tissues are shaved from a surface
Shave biopsy
Tissue samples are scooped or spooned from a cavity
Curettings
Tissues are immersed in isotonic salt solution in a petri dish or watch glass and the tissues is dissected with a needle
Teasing or Dissociation
At WHAT DIRECTION IS THE TISSUE SEPARATED IN TEASING OR DISSOCIATION?
Direct or zigzag
The selected tissue is wet mounted on amicroscopic slide. Slides are viewed either supravital stain or unstained
Teasing or Dissociation
The sample is place between two glass slides and prociby compressed
Squash preparation
How thick should be a sample in squash preparation?
<1mm
This is used mainly in cytological smear preparations, Cancer diagnosis, thick preparations. It can also be made permanents by fixing while wet.
Smear preparations
Application stick or platinum loopis used to rapidly and gently apply direct or zigzag the secretion onto a glass slide.
Streaking
Moderate thick film is created in a slide by teasing the mucus membrane strands
Spreading
