What is Histopathology?
Histopathology is the study of diseased tissues at the microscopic level. It involves examining tissue samples that are obtained from biopsies or surgical procedures, and identifying the changes that occur in the cells and tissues due to various diseases or injuries. Histopathology is a vital tool for diagnosis, prognosis, and treatment of many medical conditions, such as cancer, infections, inflammation, degeneration, and malformations.
What are Histopathologic Techniques?
Histopathologic techniques are the methods and procedures that are used to prepare and examine tissue samples for histopathology. They include fixation, processing, embedding, sectioning, staining, and microscopy. These techniques aim to preserve the structure and function of the tissues as much as possible, while enhancing their visibility and contrast under the microscope. Histopathologic techniques can be classified into two main categories: routine techniques and special techniques. Routine techniques are the basic steps that are applied to most tissue samples, such as fixation with formalin, processing with alcohol and xylene, embedding in paraffin wax, sectioning with a microtome, staining with hematoxylin and eosin (H&E), and viewing with a light microscope. Special techniques are the additional steps that are applied to specific tissue samples or for specific purposes, such as freezing for rapid diagnosis, immunohistochemistry for detecting antigens or antibodies, electron microscopy for ultrastructural details, or molecular techniques for genetic analysis.
Fixation is the first step in histopathologic techniques. It involves immersing the tissue sample in a chemical solution that stabilizes the proteins and prevents autolysis (self-digestion) and putrefaction (decomposition) by enzymes and bacteria. Fixation also hardens the tissue sample and makes it easier to handle. The most common fixative used in histopathology is formalin (10% buffered formaldehyde), which preserves the general morphology and architecture of the tissues. Other fixatives that are used for special purposes include alcohol (for glycogen), Bouin's fluid (for trichrome stains), Zenker's fluid (for nuclear details), or glutaraldehyde (for electron microscopy).
Processing is the second step in histopathologic techniques. It involves removing the water and other substances from the tissue sample and replacing them with a medium that is suitable for embedding. Processing usually consists of three stages: dehydration, clearing, and infiltration. Dehydration is the removal of water from the tissue sample by passing it through a series of increasing concentrations of alcohol (usually ethanol or isopropanol). Clearing is the removal of alcohol from the tissue sample by passing it through a solvent that is miscible with both alcohol and the embedding medium (usually xylene or toluene). Infiltration is the impregnation of the tissue sample with the embedding medium (usually paraffin wax or plastic resin) by placing it in a heated chamber or a vacuum oven.
Embedding is the third step in histopathologic techniques. It involves enclosing the tissue sample in a solid block of the embedding medium, which provides support and protection for the tissue sample. Embedding can be done in two ways: paraffin embedding or frozen section embedding. Paraffin embedding is the most common method, which involves pouring molten paraffin wax over the tissue sample in a metal mold and allowing it to cool and solidify. Frozen section embedding is a rapid method, which involves freezing the tissue sample in liquid nitrogen or carbon dioxide and cutting it with a cryostat (a device that combines a freezer and a microtome).
Sectioning is the fourth step in histopathologic techniques. It involves cutting thin slices of the tissue sample from the embedded block, which are then mounted on glass slides for staining and microscopy. Sectioning can be done with two types of instruments: microtome or cryostat. Microtome is a device that uses a sharp blade to cut sections from paraffin-embedded blocks, which are usually 4 to 10 micrometers thick. Cryostat is a device that uses a cold blade to cut sections from frozen-embedded blocks, which are usually 5 to 20 micrometers thick.
Staining is the fifth step in histopathologic techniques. It involves applying dyes or other substances to the tissue sections, which enhance their visibility and contrast under the microscope. Staining can be classified into two main types: routine stains and special stains. Routine stains are the basic stains that are applied to most tissue sections, such as hematoxylin and eosin (H&E), which stain the nuclei blue and the cytoplasm pink, respectively. Special stains are the additional stains that are applied to specific tissue sections or for specific purposes, such as Gram stain (for bacteria), Ziehl-Neelsen stain (for acid-fast bacilli), Periodic acid-Schiff stain (for carbohydrates), Masson's trichrome stain (for collagen), or immunohistochemistry (for antigens or antibodies).
Who is Bruce Gregorios?
Bruce Gregorios is a Filipino pathologist who is widely recognized as an authority on histopathology. He was born on June 8, 1930 in Manila, Philippines. He obtained his medical degree from the University of Santo Tomas in 1954, and his master's degree in pathology from McGill University in 1959. He became a professor of pathology at the University of Santo Tomas in 1961, and served as the dean of its Faculty of Medicine and Surgery from 1971 to 1977. He also held various positions in national and international organizations, such as president of the Philippine Society of Pathologists, vice-president of the International Academy of Pathology, and consultant of the World Health Organization. He has authored or co-authored over 200 publications, including several textbooks on histopathology, such as Histopathologic Techniques (first published in 1974) and Textbook of Neuropathology (first published in 1989). He has received numerous awards and honors for his contributions to pathology, such as the Outstanding Thomasian Alumni Award, the National Research Council Achievement Award, and the Order of Lakandula.
