LESSON 1 Flashcards
preparation, processing and staining of tissue sections for
microscopic study to be interpreted by the pathologist
HISTOTECHNIQUES
study of disease at the tissue level
HISTOPATHOLOGY
examined to determine the cause of death
Autopsy Materials
otherwise referred to as surgical or biopsy materials; examined to provide
a diagnosis
Surgical Materials
removal of cells from the area of abnormality
➢ considered as the simplest and least invasive method of collecting biopsy
specimens
➢ method of collection for fluid-containing tumors
FINE NEEDLE ASPIRATION
removal of cells and small amount of surrounding tissue
CORE NEEDLE BIOSY
removal of cells with more surrounding tissue
INCISIONAL BIOPSY
removal of the entire area in question
➢ Ensure complete removal of the lesion
➢ Confirm that the diagnosis is correct
EXCISIONAL BIOPSY
removal of 3 to 4 mm cylindrical core of tissue samples
➢ small: 2mm; large: 4mm
➢ lesion should be at the center
PUNCH BIOPSY
removal of small fragments of tissue from a surface
SHAVE BIOPSY
removal of tissue or growths from body cavities
CURETTINGS
Storage of Specimen
1 month to 1 year
Storage of Tissue Blocks
3 to 10 years
Storage of Slides
Indefinite
Storage of Records (request and result forms)
Permanent
- Structural and chemical components to be studied
- Nature and amount of sample to be evaluated
- The need to provide an immediate diagnosis
