Biopsy Tissue Categories: Introduction, Types, and Keynotes

Introduction of Biopsy Tissue Categories

As you know, histopathological reporting is really a hard service since pathologists are playing with the specimens who are suspected of malignancy and false-negative reporting may cause serious conditions in a patient. They have also to manage biopsy tissue blocks for a certain duration. If the clinicians/ oncologists are not clinically satisfied with the report in such a scenario they may advise visitors of the patient to bring the block for cross-checking from other pathologists. Biopsy tissue categorization is not only beneficial for proper logging of the above issue-resolving but also for managing the price of biopsy tests and report dispatching time. It is categorized into the following types on the basis of size-

Keynotes

  • Fine needle aspiration cytology (FNAC) is intervention cytology and is useful in conditions like cysts and nodules or masses under the skin, enlarged lymph nodes, and pleural and pericardial fluid analysis.
  • Exfoliative cytology is a branch of cytology in which the cells that a pathologist examines are either “shed” by the body naturally (e.g. sputum, urine, vaginal or nipple discharge) or are manually scraped or brushed (exfoliated) from the surface of the body tissue (Pap smear, gastrointestinal tract specimens during an endoscopy).
  • Common specimens for cytology are cervix (mention last menstrual period-LMP), sputum, bone marrow, and FNAC.
