The Nugget
- Histopathology is the study of tissue diseases, emphasizing the importance of recognizing normal tissue structure to identify changes indicative of disease. Understanding histopathology involves processing specimens from surgeries or biopsies to diagnose various conditions.
Make it stick
- 🏥 Histopathology studies disease through tissue examination.
- 🔬 Histo technology involves microscopic detection of abnormalities.
- 🧪 Fixation preserves tissue integrity and structure.
- 💉 Biopsy techniques include fine needle aspiration, excision, and core needle biopsies.
Key insights
Introduction to Histopathology
- Histopathology builds on knowledge from histology and focuses on the structure of tissues altered by disease.
- Key changes in tissues can be identified through histopathological studies which help diagnose conditions like cancer.
Specimen Collection and Processing
- Surgical Specimens: Collected from surgeries for analysis.
- Autopsy Materials: Used to determine causes of death from mysterious diseases.
- Biopsy Techniques:
- Fine Needle Aspiration: Uses a needle to extract tissue.
- Core Needle Biopsy: Larger samples taken for detailed analysis.
- Excisional and Incisional Biopsies: Total or partial lesions examined.
Techniques in Histopathology
- Histotechnologist Responsibilities:
- Prepare specimens for microscopic evaluation.
- Perform various techniques such as fixation, dehydration, and staining.
- Specimen Preparation Steps:
- Fixation: Preserves tissue structure.
- Dehydration: Removes water through graded alcohol solutions.
- Clearing: Prepares tissues for embedding in paraffin.
- Embedding: Paraffin wax is used to create a solid block for cutting.
Advancements and Opportunities
- Emerging technologies include digital pathology and molecular pathology to assess diseases at the genetic level.
- Career paths in histopathology include positions in clinical labs, research settings, and veterinary sciences.
