Study Notes
Tissue Specimens and Biopsy Techniques
- The primary technique for obtaining full-thickness skin specimens is punch biopsy.
Autolysis
- Autolysis is the self-digestion of tissues by enzymes that leads to tissue degradation and distortion, making it challenging for histologic examination.
Accessioning Tissue Specimens
- The purpose of accessioning tissue specimens is to assign a unique identifier to each specimen, ensuring proper tracking, labeling, and documentation.
Biopsy Techniques
- Fine needle aspiration (FNA) biopsy is NOT a type of biopsy used to obtain tissue for histologic examination, as it is used to collect cells for cytologic examination.
Examining Fresh Tissues
- The advantage of examining fresh tissues is that it allows for immediate evaluation and triage, enabling rapid diagnosis and treatment.
Fixative in Histologic Techniques
- The primary purpose of fixative in histologic or histopathologic techniques is to preserve tissue morphology by preventing autolysis and decomposition.
- Fixative helps to maintain tissue structure and prevent degradation, ensuring optimal tissue preservation for histologic examination.
Invasive Biopsy Techniques
- Surgical biopsy is the most invasive biopsy technique, involving the removal of a larger tissue sample or entire lesion.
Histology and Histopathology
- The difference between histology and histopathology lies in their focus: histology studies the normal structure and function of tissues, whereas histopathology focuses on the study of diseased tissues.
